GIS Substation Testing Trolley

GIS Substation Testing Trolley is used to test the entire GIS substation with phantom loading. The trolley consists of a Primary current injection kit, a High Voltage kit, and a phase shifting transformer. The unit is divided into two parts one is the control area and the other is the power source area. In the control area sitting arrangements is there for two persons with air conditioning. Entry point in both the areas is separate. There is an access point from control area to power source area. The trolley is fitted with all the accessories for standard operation.

  • Up to 400kV of GIS substation can be tested.
  • Compact Design and technologically advanced design that helped make proper use of space and minimize the size of the equipment.
  • The equipment has been made in such a way so that it is very simple to operate, thus any person after learning once can operate it.
  • To ensure better life and for transformer winding, perfect working condition of the transformer, special insulating paper used.
  • Equipment is covered under one year warranty and is valid against manufacturing defects but not against normal wear and tear, breakage, burning, fusing, damages due to incoming power supply, improper handling, consequential and in-transit.
