Commissioning of UHV Indoor Double Shielded Laboratory for Radio Interference Voltage and Partial Discharge Measurement
Subscribe/Renew Journal
In recent years, due to advancement of technology, the transmission voltage levels are goes on increasing. Worldwide 800 kV systems is very common and in India experimental 1200 kV AC is successfully commissioned. Testing of vital equipment of such UHV transmission network is paramount importance to provide uninterrupted, reliable and quality power to the customers. Worldwide few testing laboratories having facility to test upto UHV class equipment, the Ultra High Voltage Research Laboratory (UHVRL) of Central Power Research Institute (CPRI), India is one among them. Recently, 2X600 kV, 2 A, 2400 kVA HVAC test system is commissioned in double shielded indoor laboratory at UHVRL, Hyderabad, India. This manuscript elaborates the experiences of commission of AC test system along with radio interference voltage and Partial Discharge (PD) measurement.
