Description:FIELD OF INVENTION
The present invention relates to an electrical safety system, particularly to an isolator mechanism integrated with insulators to enhance safety and reliability while operating the Gang Operated switch in high-voltage power distribution systems.
BACKGROUND OF THE INVENTION
Electric Gang Operated switch carrying high-voltage electricity (11 kV and above) pose serious safety risks during operations. Typically, the handle operated Gang Operated switch is used to make and break the electrical circuits by operating the Gang Operated switch from handle. The structure of Gang Operated switch is made of MS channels and angles. The moving and fix contacts which make and break the circuit are fixed on insulators. The insulators with moving and fix contacts are then fixed on Mild Steel channels and angles. The handle is also made of MS iron material. The Gang Operated switch moving structure is fixed at top of the pole at height of 5mtr from ground and handle at 1.5mtr from ground. The MS pipe connects the Gang Operated switch and handle so that Gang Operated switch operates by handle from ground. The Gang Operated switch is operated by hand while taking safety measure of HT gloves and safety shoes only. The HT gloves used in operation of Gang Operated switch is not full proof safe from 11KV voltage. The distance between the live parts caring high voltage and MS structure or fitting is 12-15inch. The distance between live wires to RCC or Metal pole is 15-18inch. The distance between live wires to MS pipe which is directly connected to handle is also 10-12inch. This distance is easily overcome if any live wire breaks and fall on MS structure, pole or MS pipe which leads severe damage to operator operating handle. Although the MS structure is completely earth but still operator get shock as the earth resistance of earth pits increase with age factor so these pits do not able to flow the high voltage into earth. Even if the earth resistance is low and earth pit is in healthy condition still there is heavy chance to get operator a heavy electric shock as voltage is very high in line. Having a healthy earth pit is not a full proof safety from 11KV high voltage faulty conditions.
While operating the Gang Operated switch there are many risks condition occur which lead to the generation of high voltage in handle. Some of the situations are mentioned below
1. When operator operates the Gang Operated switch the electric flash arc occurs between moving and fix contacts, this flash may jump the insulators and come in contact with MS structure of Gang Operated switch. Although the MS structure is completely earth but still operator get shock as the earthing resistance increase with age factor.
2. While operation the insulators caring fix and moving contacts may get punctured due to heavy load stress while breaking the circuit and old age of insulators. Due to which the high voltage come in contact of MS structure.
3. While operating the Gang Operated switch on Distribution transformer H-Pole. When the fault occurs in transformer the fuse gets blown and many times it happens that fuse of all three phase doesn’t blow, if any of the one phase remains connected and other two-phase fuse gets blown so due to the delta connection of windings the high voltage remains in all three phases of faulty transformer. Now due to the fault, the coil windings of transformer may get in touch with transformer body and 11KV comes directly in MS structure of complete H-Pole and in handle also. Now in this condition, if operator operates the handle to disconnect the transformer from HT line for fuse work the operator receive severe shock.
4. While operating the Gang Operated switch to open or close the high-tension line, many times the situation occurs that the jumpers (live wires caring high voltage) of line break from the fix contacts and get in touch with MS structure of H-Pole fitting as a result high voltage come in handle, where the handle is control by operator receive severe shock.
However, the conventional Gang Operated switch operating systems is prone to failures, and even a millisecond of high-voltage exposure can be fatal or cause severe burns, despite the use of protective gear like rubber gloves.
From above it is concluded that the basic solution previously proposed involved a lever-based disconnection mechanism. The lever-based disconnecting system included a shaft-mounted lever arm that physically disconnected the moving contacts. It prevents the jumped flash arc caring high voltage that flow in MS structure during faulty situation of operation to reach the handle where operator touch the handle.
Further, insufficient insulation and contact risks in traditional isolators allow flashovers and leakage currents, especially at the lever-wire and pole-lever interface. Many existing systems rely on metallic rods or conductive tools for manual operation, increasing the operator’s exposure to live components. Corrosion of metallic hinges and joints due to humidity, dust, and environmental factors leads to frequent failures and high maintenance costs. Insufficient insulation and fault conditions further add to the risk, as inadequate insulation between the isolator and conductive parts can expose operators to high-voltage arcing or leakage currents. Physical contact with live components, particularly if safety barriers are inadequate, further increases the risk of direct electrocution.
Additionally, the basic solution previously proposed involved a lever-based disconnection mechanism. The lever-based disconnecting system included a shaft-mounted lever arm that physically disconnected the live wire when operated, preventing current flow during maintenance. However, this approach proved unsafe and unreliable due to multiple inherent flaws in conventional isolators. One major drawback is the risk of residual charge and induced voltage, where high-voltage equipment retains electrical charge even after isolation. Additionally, induced voltage from nearby live conductors can unexpectedly re-energize the system, exposing workers to electric shocks. Another critical issue is the failure of the isolator mechanism, as incomplete disengagement may leave partial contact, allowing leakage currents that pose fatal risks. Mechanical faults or improper switching operations can also result in incomplete isolation, leading to hazardous conditions. Similarly, unintentional re-energization due to switching errors or accidental remote activation can suddenly restore power while maintenance is in progress. The absence of proper lockout-tagout (LOTO) procedures increases the risk of accidental power restoration, further compromising operator safety.

Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention.

The system (100) comprises a mild steel (MS) pipe (101), a fulcrum shaft (102), a first insulator (103), a second insulator (104), a lever arm (105), an upper bolt (106) and a lower bolt (107) and a holding clamp (110). The mild steel (MS) pipe (101) mounted vertically on an electric pole (300), where the MS pipe (101) is connected at its top end to a transformer (301) and connected at its bottom end to a top pipe rod (108) of first insulator (103). The first insulator (103) is strategically positioned at the upper end of the mild steel (MS) pipe (101), establishing an electrical barrier between the (MS) pipe (101) and the lever arm (105). The lever arm (105) mounted to the MS pipe (101) downstream of the transformer (301), the lever arm (105) is manually rotatable to disconnect the electrical connection between the MS pipe (101) and a supply line from an electric pole (300). The fulcrum shaft (102) connected to the lever arm (105), the fulcrum shaft (102) allowing the lever arm (105) to rotate manually to connect or disconnect the MS pipe (101) from an electrical supply line of a electric pole (300). The second insulator (104) is configured to electrically isolate the lever arm (105) from the fulcrum shaft (102) by forming a non-conductive barrier that prevents electrical current flow between the lever arm (105) and the fulcrum shaft (102). The first insulator assembly (200), can be fitted in the MS pipe (101) by cutting MS pipe (101) and inserting the insulation assembly (200) and fastening the insulation using screws (106 and 107), wherein the first insulator (103) is installed to prevent flow of electric current. The first insulator (103) is made of a high-dielectric material and includes plurality of external, annular ribs spaced along the length of the body and projecting outwardly from a smooth cylindrical portion, a top pipe rod (108) at an upper end of the first insulator (103) comprising a reduced-diameter, configured to engage and seal against the MS pipe (101) and a bottom pipe rod (109) at a lower end of the first insulator (103), comprising a reduced-diameter, configured to engage and seal against the downstream MS pipe (101). Both rods (108, 109) are embedded within a ribbed dielectric body to ensure electrical isolation and mechanical stability. The first insulator is made of epoxy by molding and the rods (108 and 109) are fixed during the molding process. The upper bolt (106) and a lower bolt (107) configured to mechanically secure the first insulator (103) to the mild steel (MS) pipe (101) at its respective upper and lower ends, ensuring stable electrical isolation and structural integrity. The holding clamp (110) configured to securely mount the fulcrum shaft (102) and lever arm (105) assembly to an electric pole (300), providing structural support and enabling controlled rotational movement of the lever arm while maintaining positional stability.
Fig. 2: Illustrate first insulator assembly with upper and lower rods, in accordance with an embodiment of the present invention. The first insulator assembly (200), which is a key component designed to electrically isolate two segments of a conductive mild steel (MS) pipe (101) while maintaining mechanical continuity. The assembly consists of a molded epoxy resin body with two embedded metal rods — an upper rod (108) and a lower rod (109). The top pipe rod (108) is positioned at the upper end of the insulator. It is designed to insert securely into the upstream section of the MS pipe (101) and provide a conductive path from the transformer (301) side while being electrically insulated from the downstream components. Similarly, the bottom pipe rod (109) is located at the lower end of the insulator and connects to the downstream MS pipe (101) section. Both rods are firmly embedded during the epoxy molding process, which ensures strong adhesion and alignment within the insulating body. The insulating body itself is made from high-dielectric epoxy resin, molded into a ribbed profile. These external ribs are strategically designed to increase the creepage distance, which enhances the dielectric performance, especially in high-voltage and outdoor environments. The ribs also serve to minimize the risk of surface tracking and flashover, making the assembly suitable for use in areas subject to moisture, dust, and pollution. The first insulator assembly (200) plays a critical role in breaking the electrical path between two conductive sections of the MS pipe while retaining structural stability. It is typically installed by cutting the pipe and inserting the insulator assembly, which is then mechanically fastened using bolts to ensure a secure fit and reliable insulation.
Fig. 3 illustrates an on-site installation of an electrical safety system mounted on an electric pole, in accordance with an embodiment of the present invention. The system is mounted on an electric utility pole (300) and comprises The Transformer (301) supplies electrical power, which is transmitted through a mild steel (MS) Pipe (101), a vertical pipe that conducts electricity down the system. The first insulator (103), a high-dielectric epoxy component, is inserted into the MS pipe to interrupt electrical continuity and ensure proper isolation. It is connected at both ends to the MS pipe by the top pipe rod (108) and the bottom pipe rod (109), which embed into the insulator, sealing it to the upper and lower sections of the pipe.
The Upper Bolt (106) and Lower Bolt (107) are used to securely fasten the first insulator within the MS pipe, preventing any disconnection. For manual control of the system, a lever arm (105) is used to connect or disconnect the electrical flow by pivoting around the fulcrum shaft (102), which serves as the pivot point. The second insulator (104) electrically isolates the lever arm from the fulcrum shaft, preventing current transfer through the mechanism. Finally, the holding clamp (110) secures the fulcrum shaft and lever arm assembly to the utility pole, providing the necessary structural stability for the entire system.
In accordance with an exemplary embodiment of the present invention, the system (100) is designed to ensure safe disconnection of an electrical line from a support structure while minimizing the risk of electrical hazards to the operator. The system (100) incorporates a combination of mechanical and insulating components to provide a fail-safe isolation mechanism, ensuring that no electrical continuity exists between the high.
In accordance with an exemplary embodiment of the present invention, the system (100) of present invention overcomes the limitations of traditional isolation mechanisms, which often fail due to mechanical wear, operational errors, or environmental factors. In conventional isolators, metallic components used for manual operation expose the operator to electric shock risks. Additionally, isolators that lack dual insulation can allow leakage high voltage/ main supply current to pass through and leading to hazardous conditions. By incorporating a dual-insulator safety mechanism, the present invention eliminates any possible conductive path between the live circuit, the operator, and the support pole. Unlike traditional isolation systems, which are prone to sensor failures, relay malfunctions, or power dependency, the system (100) of present invention is purely mechanical and passive, ensuring long-term reliability and safety.. Furthermore, the design of the present invention allow the system (100) to be retrofitted onto existing utility poles without requiring major modifications which makes system (100) of the present invention a cost-effective and scalable solution for improving high-voltage maintenance safety across urban, rural & Sub Stations power distribution networks.
Functional Operation:
The system (100) operates as a mechanical isolator that safely breaks the electrical connection between a transformer (301) and the downstream power line, especially in outdoor or high-voltage environments. It achieves this by integrating conductive and non-conductive elements in a modular and field-installable design. The system (100) is anchored by a vertically mounted mild steel (MS) pipe (101), which acts as a primary current-carrying element. Positioned within this pipe is a first insulator (103) made of high-dielectric epoxy material. This insulator provides electrical isolation between the upper and lower segments of the MS pipe and is securely fastened using bolts (106, 107). Embedded within the epoxy body are two rods (108 and 109), which interface mechanically and electrically with the MS pipe sections. The lever arm (105) is attached below the insulator. It is manually operable and connected to a fulcrum shaft (102) that enables rotational motion. The fulcrum is fixed onto the pole using a holding clamp (110) and allows the lever to rotate along a defined arc — typically about 150 mm downward and 200 mm upward — for controlled switching operations.
The second insulator (104), installed between the lever arm and fulcrum shaft, serves as a non-conductive barrier, preventing any electrical current from traveling between these mechanical elements. This enhances operator safety during operation and protects the system against unintended short circuits or leakage currents. In a typical operation, when the lever arm is in the neutral or connected position, current flows from the transformer (301) through the upper MS pipe, across the embedded rods in the first insulator, and into the lower MS pipe, continuing to the power distribution network. To disconnect the line, the operator manually rotates the lever arm via the fulcrum shaft. This motion either breaks the physical connection between the MS pipe and the supply line or causes a misalignment that stops current conduction — effectively isolating the transformer (301).
In accordance with an exemplary embodiment of the present invention, the system (100) provides several technical and operational advancements over conventional isolator systems. Key enhancements over the prior art include:

Integrated high-dielectric insulation assembly (200)
The inclusion of a first insulator (103), formed via epoxy resin molding with embedded rods (108, 109), ensures superior dielectric performance up to 60 kV. Its ribbed profile increases creepage distance, enhancing reliability under high-voltage and outdoor conditions — an advancement over flat or non-integrated insulation units.
Field-replaceable modular design
The first insulator assembly (200) is modular and designed to be fitted directly into a cut section of the MS pipe (101). This allows for quick field installation or replacement without requiring complete disassembly, unlike rigid, fixed insulator systems found in earlier designs.
Double-layer second insulator (104) for enhanced protection
The second insulator (104) features a dual-material construction — an inner core of glass fiber-reinforced epoxy resin and an outer silicone elastomer coating — offering improved resistance to environmental stress, mechanical loads, and high-voltage arcing. This layered approach provides better performance than single-material bushings or sleeves.
Manual lever operation with safety enhancements
The lever arm (105) is manually operable and designed to move through a controlled arc, allowing safe disconnection without needing energized contact. The arm is either coated in insulating rubber sleeves or constructed from high-strength fiberglass to ensure user safety, even during high-voltage operations — an enhancement not typically available in bare-metal systems.
Improved mechanical fulcrum assembly
The fulcrum shaft (102) is made of galvanized iron, offering durability and corrosion resistance. Its configuration supports controlled manual movement and stability even under wind or vibration, which is more robust than prior assemblies with limited motion tolerance or unsealed pivot points.
Enhanced operator safety and accessibility
The system is designed for manual actuation from a safe distance (e.g., 2 meters), enabling maintenance crews to isolate circuits without the need for insulated tools or live-line procedures. Prior systems often required close proximity or hot-stick usage, increasing operational risk.
Simplified installation and maintenance
Use of bolts (106, 107) to secure the first insulator enables non-invasive mechanical fastening while maintaining electrical insulation. This simplifies periodic checks, testing, or part replacements — a significant usability advantage over prior fixed-joint or welded solutions.
These enhancements collectively provide a fail-safe, cost-effective, and retrofittable solution, making the system highly suitable for deployment across varied power distribution infrastructures, including urban, rural, and substation environments.
