BACKGROUND
[0002] 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] Conventionally, switchgear is used for regulating and switching on
or off the electrical circuit in the electrical power system. The switchgear is a factory assembled, metal enclosed panel used at the various transmission and distribution level of an electrical power system. The measurement and inspection of the critical aspects of the switchgear is important. One of the critical aspects is the minimum distance between the phases carried by busbars. The busbars refer to metal bars that are used to carry large amount of current. As the switchgear latest trend is to make as compact switchgear as possible. So, in some situations we cannot measure the distance between busbars as they are in accessible. For that we have developed a gauge for measuring the minimum busbar distance of inaccessible busbars.
[0004] There is, therefore, a need of a device or method for measuring and
verifying minimum required distance between adjacent busbars.

[0035] As illustrated, a device 100 for checking and measuring relative
distance between adjacent busbars and busbar to earthed components in a switch gear can include a first longitudinal member 102 (also referred as longitudinal first member or first member, herein) can include but not limiting to a rod, a stick, a flexible rod of either metal or non-metal, and like. The first member 102 can have a pre-defined length. A second member 104 can be selected from a group of or plurality of second members 104-1, 104-2, 104-3... 104-n (collectively referred as second members 104 and individually referred as second member 104). The second member 104 can be removably coupled with a first end of the first member 102. The second member 104 can be removably coupled with the first end using but not limited to thread arrangement in the second member 104 and the first end. The first member 102 can be used to hold the device 100 and can be used to facilitate moving or dragging the second member 104 between the adjacent busbars 108 or between the busbar and earthed components (not shown) in the switchgear. The second member 104 can be moved between the adjacent busbars 108 along a length or longitudinal axis of the busbars 108. The first pre-defined length can be selected such that the first member can easily facilitate moving the second member 108 along the length of busbars 108.
[0036] In an embodiment, each of the plurality of the second members 104
can be of a pre-defined dimension. The second member 104 can be of a cross-section shape from circular, spherical, and polygon. The pre-defined dimensions can include but not limiting to a diameter, length, and width. The second member 104 can be selected from the plurality of second members 104 based on a requirement of minimum distance between the adjacent busbars 108 in the switchgear. There can be multiple busbars in a switchgear which can have different minimum distance requirements between the adjacent busbars, one of the (also referred as second member, herein) plurality of second member 104 can be selected accordingly. In an embodiment, the first member 102 and the plurality of

second members 104 can be made of non-conductive material such as but not limiting to wood, rubber, and fibre.
[0037] The device can facilitate measuring and verifying if the minimum
distance requirements between the adjacent busbar are met. If the second member
can easily move between the adjacent busbars without any obstruction, that
verifies that the requirement of having minimum distance between the adjacent
busbar are met. Otherwise, necessary actions can be taken to comply with the
requirements prior to any mishappening or failure. This checking or measurement
process can start with the electrical shut down of the Ring Main Unit. The gas
present in the RMU tank can be evacuated. The inspector can check or measure
the gap between busbars or busbar to earthed components gap using the device.
The inspectors are required to use the protective gears while doing the inspection.
[0038] In an embodiment, the first member can be either a stiff rod or
flexible in nature to reach inaccessible areas. Relative distance between two phases or busbar and earthed component (for example switchgear tank sheet) can be measured using the proposed device. Relative distance between adjacent busbars in a switchgear that are not parallel with each other can also be measured using the proposed device and the proposed device can guide placement of busbar in the switchgear.
[0039] Moreover, in interpreting the specification, 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 refer 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.
