[0001] The present disclosure relates to the field of gas-insulated switchgear. More particularly the present disclosure relates to an arrangement for an electrically connecting potential transformer with a conductive path of gas-insulated switchgear.

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] Typical gas-insulated switchgear (GIS) consists of a cable chamber where incoming cable or outgoing cables are terminated, a VCB chamber, to switch ON & OFF the switchgear & Busbar chamber with or without disconnecting switch. The disconnecting switch is generally of 3 Positions, ON, OFF& EARTH. Disconnecting Switch or Disconnector plays a very important role in earthing the switchgear so that it can be taken under maintenance. To earth any switchgear, it is critical to ensure that the conductive path of the gas-insulated switchgear is not live. These inputs of whether the line is live or dead, are given by a potential transformer (PT). When the system is under maintenance, it is critical to ensure that PT is also earthed & it is achieved by switch arrangement.
[0004] There is, therefore, a need for an arrangement for an electrically connecting potential transformer with a conductive path of gas-insulated switchgear to check the electrical status of the conductive path of the gas-insulated switchgear.
