High Voltage Insulating Tester


Provided with a built-in high voltage source of 0-10kVdc, DAC-HIT-3 is a designable insulation tester for high voltage rotation machines and stator coils. The tester allows knowing a polarity index (PI) to judge a condition of degradation or absorption as well as a leakage index (LI) to see a status of absorption and dryness.
A memory function can store data at each time, and GP-IB interface allows automatic measurement and data processing with a PC.
Costomized insulation diagnostic systems including DAC-HIT-3 are available upon request.


Direct current tests of high voltage rotating machines and stator coils.


Maximum output voltage
Polarization index (PI) and leakage index (LI) are automatically measured
GB-IB included suitable for optimization
