This set is suitable to calibrate High voltage measurements. It consists of -
i. High Voltage PT
ii. Measurement unit

High Voltage PT
One end of PT winding is grounded.
Max. Measurement Voltage: Depending on PT, spread over different range upto 100KV i.e. 10KV, 40KV & 100KV. Secondary Voltage: Depends on Primary High Voltage but restricted to 1000V.

Measurement unit: Digital voltmeter.
Accuracy of measurement: + 1%.
Interconnecting cable between the PT secondary and voltmeter is of at least 3 meters length.
