TECHNICAL FIELD
[0001] The present disclosure generally relates to the field of electrical safety devices.
In particular, the present disclosure relates to electrical shock prevention. More particularly,
the present disclosure relates to electrical safety device that prevents any user from receiving
an electric shock upon coming in contact with electric circuit or component/unit thereof and
hazard of short circuit is also eliminated.
BACKGROUND
[0002] The background description includes information that may be useful in
understanding the present invention. It is not an admission that any of the information
provided herein is prior art or relevant to the presently claimed invention, or that any
publication specifically or implicitly referenced is prior art.
[0003] Life today seems unimaginable without electricity and different
appliance/devices/equipment (also known as and therefore hereinafter referred to as electrical
units) run on electric power. Electricity along with its utility also has health and safety
hazards. Prominent among these hazards are electric shocks that can severely affect a person
such as in case of contact (mostly inadvertent) with an electrical unit, more particularly with a
live wire (having a high potential) of the same, while the person is also in contact with
ground or a neutral wire, causing current to flow through his/her body. Such flow can be
extremely dangerous, and even fatal.
[0004] Technically speaking, an electrical unit usually has three wires- live, neutral
and ground (alternatively, earth) - of which the neutral and ground have zero potential while
the live wire has a high potential as also mentioned before. So, whenever a person without
proper insulation comes in contact, almost simultaneously, with live wire and ground, a high
current of the order of 240V/120V (depending upon power supply in the region) manages to
flow through the person’s body into the ground. There have been efforts in the past to address
the instant issue but with low or minimum gains. Further, efforts to obtain shock-free
functioning of an electrical unit/circuitry lead to undesired stepping down of output voltage
thereof.
[0005] Electrical circuits are designed to allow only a limited amount of current to
flow through. The limitation on the current is largely due to the resistance or impedance of
the load to which it is connected. If the resistance or impedance of the load is bypassed,
2
or shorted, then, according to Ohm’s law, an abnormally high current will flow through the
circuit. This situation is called a short circuit. Depending on the remaining resistance or
impedance of the circuit, the short-circuit current could be up to 30 times as high as the
normal current. At this abnormally high level, most equipment and wiring will be ruined by
the excessive amount of heat generated. Furthermore, there will most likely be fire of
combustible components in the vicinity.
[0006] There is a need in the art to provide an electrical safety device that can obviate
instances of shock from live wires to a user of an electrical circuit and also assist in
eliminating the hazards caused due to short circuit, while checking undesired change in
output power of the electric circuit. Notably, it would be a desirable feature in case the
proposed safety device could deliver aforementioned benefits without requiring use of any
relay to provide insulation for different applications, most commonly for households.

[0032] As used in the description herein and throughout the claims that follow, the
meaning of “a,” “an,” and “the” includes plural reference unless the context clearly dictates
otherwise. Also, as used in the description herein, the meaning of “in” includes “in” and “on”
unless the context clearly dictates otherwise.
[0033] Exemplary embodiments will now be described more fully hereinafter with
reference to the accompanying drawings, in which exemplary embodiments are shown. These
exemplary embodiments are provided only for illustrative purposes and so that this disclosure
6
will be thorough and complete and will fully convey the scope of the invention to those of
ordinary skill in the art. The invention disclosed may, however, be embodied in many
different forms and should not be construed as limited to the embodiments set forth herein.
Various modifications will be readily apparent to persons skilled in the art. The general
principles defined herein may be applied to other embodiments and applications without
departing from the spirit and scope of the invention. Moreover, all statements herein reciting
embodiments of the invention, as well as specific examples thereof, are intended to
encompass both structural and functional equivalents thereof. Additionally, it is intended that
such equivalents include both currently known equivalents as well as equivalents developed
in the future (i.e., any elements developed that perform the same function, regardless of
structure). Also, the terminology and phraseology used is for the purpose of describing
exemplary embodiments and should not be considered limiting. Thus, the present invention is
to be accorded the widest scope encompassing numerous alternatives, modifications and
equivalents consistent with the principles and features disclosed. For purpose of clarity,
details relating to technical material that is known in the technical fields related to the
invention have not been described in detail so as not to unnecessarily obscure the present
invention.
[0034] All methods described herein can be performed in any suitable order unless
otherwise indicated herein or otherwise clearly contradicted by context. The use of any and
all examples, or exemplary language (e.g., “such as”) provided with respect to certain
embodiments herein is intended merely to better illuminate the invention and does not pose a
limitation on the scope of the invention otherwise claimed. No language in the specification
should be construed as indicating any non-claimed element essential to the practice of the
invention.
[0035] Various terms as used herein are shown below. To the extent a term used in a
claim is not defined below, it should be given the broadest definition persons in the pertinent
art have given that term as reflected in printed publications and issued patents at the time of
filing.
[0036] According to an aspect of the present disclosure an electric shock protection
device (EPSD) is disclosed. The EPSD can be installed in parallel to a live or a phase wire. In
case when the live or the phase wire is carrying current and any person or a thing comes in
contact with the live or the phase wire carrying a current. In such a case, the EPSD provides a
low resistance path to the flow of current such that the circuit for flow of current to the load is
7
not broken and an electric shock is also prevented. Further the EPSD helps elimination of
short circuit as well under any given circumstance.
[0037] As used herein, a person having ordinary knowledge in the art would
appreciate that “live wire” (high voltage 120-240V as per power supply in the region) is
connected directly to generators of the electricity supplier, “neutral wire” (nearly zero
volts) is to return the electricity to the generator after it has passed through the appliance.
Further, the neutral wire completes the circuit. Moreover, “earth wire” usually does not carry
electricity and serves as a safety measure. Put another way, if the appliance malfunctions or is
inappropriately wired, then the earth wire may carry the same current as the live wire.
[0038] FIG.1 illustrates an exemplary representation of an electrical safety device in
accordance with an embodiment of the present disclosure.
[0039] In context of an exemplary circuit diagram 100, an alternating current (AC)
input from the AC input source can be provided to an electronic shock protection device
(EPSD) 102. The EPSD 102 can comprise an AC input terminal (not shown) to accept the
AC input from the AC input source. The EPSD 102 can further comprise various electronics
components (not shown) connected to the AC input terminal. The various electronics
components can be arranged in an arrangement. Now, the arrangement of the various
components can generate an output based on the received AC input. The generated output can
be supplied to an AC output terminal (not shown). The AC output terminal can further supply
the output to load 104. In an embodiment, the load 104 can include one or more loads.
[0040] In an embodiment, the output generated by the various components allows
uninterrupted supply of electric power to the load 104 if an event of short circuit occurs in the
circuit.
[0041] In an embodiment, the output generated by the various components enables
prevention of an electric shock to a user if the user comes in contact with electric wires
conducting electric power.
[0042] In an embodiment, the various components can include but not limited to a
resistance and a coil. In an embodiment, when the wires conducting electric power to the load
104 gets shorted or an event of a short circuit occurs, the conduction of the electric power to
the load 104 is not interrupted and further, the hazard caused due to short circuit could also be
avoided.
[0043] In an embodiment, the load can include an equipment, a device, household
components, electronic components and the like
8
[0044] FIG. 2 illustrates an exemplary representation of an electrical safety device in
accordance with an exemplary embodiment of the present disclosure.
[0045] In context of an exemplary circuit diagram 200, an alternating current (AC)
input can be connected to an isolation transformer 202. The isolation transformer can be used
to transfer electrical power from the AC input to main circuit of a load 208 while isolating the
powered device from the power source, usually for safety reasons. The load 208 can include
an equipment, a device and the like.
[0046] In an embodiment, a switch 204 can be configured across the load 208. The
switch 204 can be configured to trip or disconnect when imbalance or mismatch in electric
current of the circuit is detected.
[0047] Further, an electric shock prevention device (EPSD) 206 can be connected in
parallel to live/phase wire supplying current to the load 208. Now, when the switch 204
detects an imbalance in the current probably because of any person coming in contact with
the live/phase wire, a trigger can be generated and sent to the EPSD 206. Based on the
trigger, the EPSD can be turned ON and can generate a low obstruction path to the flow of
current. Further, since the path of current to the load 208 is not broken, the load remains ON
and the electric shock can thus be prevented.
[0048] Although the proposed system has been elaborated as above to include all the
main modules, it is completely possible that actual implementations may include only a part
of the proposed modules or a combination of those or a division of those into sub-modules in
various combinations across multiple devices that can be operatively coupled with each other,
including in the cloud. Further the modules can be configured in any sequence to achieve
objectives elaborated. Also, it can be appreciated that proposed system can be configured in a
computing device or across a plurality of computing devices operatively connected with each
other, wherein the computing devices can be any of a computer, a laptop, a smart phone, an
Internet enabled mobile device and the like. All such modifications and embodiments are
completely within the scope of the present disclosure.
[0049] As used herein, and unless the context dictates otherwise, the term “coupled
to” is intended to include both direct coupling (in which two elements that are coupled to
each other or in contact each other) and indirect coupling (in which at least one additional
element is located between the two elements). Therefore, the terms “coupled to” and
“coupled with” are used synonymously. Within the context of this document terms “coupled
to” and “coupled with” are also used euphemistically to mean “communicatively coupled
9
with” over a network, where two or more devices are able to exchange data with each other
over the network, possibly via one or more intermediary device.
[0050] Moreover, in interpreting both the specification and the claims, all terms
should be interpreted in the broadest possible manner consistent with the context. In
particular, the terms “comprises” and “comprising” should be interpreted as referring to
elements, components, or steps in a non-exclusive manner, indicating that the referenced
elements, components, or steps may be present, or utilized, or combined with other elements,
components, or steps that are not expressly referenced. Where the specification claims refers
to at least one of something selected from the group consisting of A, B, C ….and N, the text
should be interpreted as requiring only one element from the group, not A plus N, or B plus
N, etc.
[0051] While some embodiments of the present disclosure have been illustrated and
described, those are completely exemplary in nature. The disclosure is not limited to the
embodiments as elaborated herein only and it would be apparent to those skilled in the art
that numerous modifications besides those already described are possible without departing
from the inventive concepts herein. All such modifications, changes, variations, substitutions,
and equivalents are completely within the scope of the present disclosure. The inventive
subject matter, therefore, is not to be restricted except in the spirit of the appended claims.
