India: Switchgear engineering division of BHEL has developed a compact and cost-effective bus potential transformer module for a 33 kV gas insulated switchgear.
The removes obviates the need for a separate PT panel in the GIS switchboard. In the existing design, a separate PT panel was provided, having size, weight and cost same as a regular feeder panel. The new top-mounted bus PT module has been developed for the first time by the Indian GIS manufacturer. The new PT module was successfully developed, installed and commissioned at a substation site (HVPNL, Sector – 107 Gurugram, Haryana).
The new development has ensured a cost saving of 57 %. In addition, the size and weight of the panel has been reduced by 80 % in comparison with the conventional PT panel. This is also an environmentally friendly design, consuming less sulphur hexafluoride (SF6) gas, thus reducing the carbon footprint.
The cost of the PT panel is furthermore reduced by its development under Make in India and Aatmanirbar Bharat initiatives of the Government of India. A patent has been awarded to BHEL for this innovative design.
