A) FIELD OF TECHNOLOGY
1. The present invention relates generally to electric powered trip units, such as circuit breakers and more particularly sensing and recording the status of the circuit breaker. This involves electrical monitoring through converting control voltage to current in order to monitor the status of the breaker and the communication to the master communicator is done through Modbus protocol.
B) DESCRIPTION OF PRIOR ART:
2. This invention relates to a method and apparatus for sensing the status of the circuit breakers and recording the status information for future analysis and debugging purpose. The invention claimed by the applicants describes a circuit breaker status indicator that incorporates a lighted visual display with memory unit for storing the stams information provides a common master communicator for the parallel monitoring
3. Evaluation of relevant patents in this field has revealed that All previously issued patents describe a circuit that uses a single indicator to indicate either the "OPEN/TRIPPED" or the "CLOSED" position, or uses multiple indicators (usually separate LEDs) for displaying the status alone. Some of the issued patents require that a parallel circuit or set of contacts be implemented together with the circuit breaker, switch, or fuse in order to activate the indicator Ught. Some patents in this area require active elements to monitor the status of the circuit breaker or

switch. Such circuits are less reliable and more expensive than circuits that use only passive elements.
4. None of the technologies in existing patents incorporates memory unit that can store the status information for future use. Finally, all circuits described in related patents are designed to be used with specific supply voltages and will not function correctly outside that supply range. The invention claimed by the applicant's addresses the above-mentioned problems. It describes a circuit breaker status indicator that incorporates a lighted visual display with memory unit for storing the status information provides a common master communicator for the parallel monitoring. The Breaker Stams Module uses an inexpensive, passive electronic circuit and intelligent method that takes advantage of memory unit that can store history information for future use.
5. The Breaker Status Module uses an inexpensive, passive electronic circuit and intelligent method that takes advantage of memory unit that can store history information for future use.
C) OBJECT OF THE INVENTION:
6. It is the primary object of the invention to invent a sensing method and apparams that can able to record the stams and changes in the stams of the circuit breakers.
7. It is another object of the invention to invent a precise method by recording the Date and Time stamps.
8. It is another object of the invention to invent a system that can sense and record the multiple circuit breakers at a time with single integrated master.

9. It is another object of the invention to invent a system that can able to detect the status of three different isolated inputs from different parts of the breaker.
10. It is another object of invention to invent a system that stores up to ten previous status history of each input that is stored in the BSM module for future reference.
11. It is another object of invention that provides thirty two such BSM modules with different node addresses that are connected in parallel for communicating with master communicator.
12. It is another object of the invention to invent a status monitoring system, which is easy to implement and interpret the results for analysis.
D) PROPOSED SOLUTION:
13. We propose a novel design in the field of sensing and recording the status and change in the status of circuit breakers. The novelty of this design provides an intelligent module that stores the date and time stamps for the precise monitoring of breakers. The unit houses an LED to indicate the Power-ON status & an LED to indicate the communication status and LEDs to indicate the tripped status of the circuit breaker. The stored status information can be accessed by any master communicator through Modbus communication protocol using RS485 interface. In addition this system has the capability of keeping history of status information up to 10 records. The system also has the capability of accessing to the maximum of thirty-two modules. Multiple modules are accessed through node address dip switch on a single master communicator.
14. The block diagram of the system is shown in figure 1. The system consists of a master communicator with RS 485 interface for the communication and BSM (Breaker Status Modules) units. The BSM consists of a power supply unit, Micro

controller, memory unit, a voltage to current converter, an isolator and with communication circuit. A single system can hold up to 32 BSM units for parallel monitoring.
15, The module operates with and external 24VDC power supply. The contacts of the breaker that are to be monitored are connected to the input terminals of the BSM module. The voltage across the contacts can be from 24V DC/AC to 265V AC/DC. The circuit inside the BSM module converts the voltage across the input terminals of the BSM module to a constant current with isolation. This current is again converted to voltage, which is used by the micro-controller inside to detect the change in the status of the inputs. Any change in the status of the inputs will be recorded by the BSM module with DATE and TIME stamp. Up to 10 records of the each input will be stored in the BSM module. The status information contains whether the system is ON/ OFF/ TRIPPED. The advantage of the time stamping information provides to let the user know when the breaker serviced, ON, OFF and TRIPED. All the stored records of status information can be accessed by any master communicator using Modbus protocol. The BSM modules are in communication with the master through RS 485 communication interface.
E) BEST METHOD OF PERFORMANCE
16. To summarize, the system presented here is implemented by designing a BSM module for the status detection as well storing those informations for the future use. The entire system houses a Master communicator and a maximum of 32 BSM modules with RS 485 interface for the connecting with the master. The communications between master communicator and BSM modules are done by employing Modbus protocol.
• Lighted status indicators are used for displaying the status of the breaker such as ON/ OFF and TRIPPED.

• A memory module with each BSM unit are used for storing the status informations.
• A master communicator is connected with a single BSM unit or with a maximum of 32 BSM units for parallel status monitoring.
• Three inputs are taken from the circuit breaker from different parts of it.
