2.1 High Voltage Laboratory

The reliability and safe operation of a high voltage system depends upon the integrity of its insulation. A high voltage test is essential to examine this integrity and to determine the ability of the insulation to meet its design specifications. In view of this a High Voltage Laboratory has been set up with following objectives:

  • To support the developmental activities of Accelerator Programme requiring high voltage dc and pulsed power converters.
  • To promote the high voltage and dielectric research activities.
  • To generate systematic practical training among the people working in high voltage fields.

To support its objectives, the High Voltage Laboratory is equipped with the following test and measuring equipments:
  • 100 KV, 5 KVA, 50 Hz, PD free testing transformer.
  • 400 KV, 7.5 mA DC voltage source.
  • 420 KV, 740 Joules impulse generator.
  • 500mm, motorized sphere gap assembly.
  • HAGNUK(German) make hand held partial discharge detector.
  • 500 MHZ, Digital Storage Oscilloscope with recorder.
  • 100 kVrms Transformer oil breakdown tester.
