This equipment is mainly used for partial discharge measurement of the 36 kV
sytem voltage level for power products such as CT&PT ,transformers, surge
arrester, high voltage circuit breakers, cables accessories, products for power
frequency voltage withstand test and partial discharge test and research pilot.
Technical specification conform to IEC 60270 .
