Soken DAC-HIT-3 - High Voltage Insulating Tester

DAC-HIT-3 is a tester that has been developed to make automatic measurements of direct current tests of appliances such as high voltage rotating machines and stator coils. The measurement voltage is output between DC 0-10kV, and after selecting polarization index (PI) mode or leakage index (LI) mode, measurement is conducted automatically for the designated duration at the configured voltage. In addition, using the memory function, data can be stored at each time, and data can be checked by using the MEM keys in front of the tester.

Furthermore, the GP-IB interface that allows easy integration of automatic test systems is equipped so it can be used in insulation diagnostic systems.

Application

PI (polarization index) test: Measurement for 10 minutes at the designated voltage.

• Data memory points: 24 points
• Memory data intervals: 10-second intervals from 10 seconds to 1 minute, 30-second intervals from 1
• minute to 10 minutes
• PI = value at 1 minute after applying voltage/value at 10 minutes after applying the voltage

LI (leakage index) test: After the PI test (10 minutes), the leakage current is measured for 10 minutes in
discharging condition.

• Data memory points: 48 points (including 24 points in the PI test)
• Memory data intervals: 10-second intervals from 10 seconds to 1 minute, 30-second intervals from 1 minute to 10 minutes, 10-second intervals from 10 minutes to 11 minutes, 30-second intervals from 11 minutes to 20 minutes
• LI = value at 10 minutes after applying voltage/value at 10 minutes after starting discharge
