DAC-HIT-3

DAC-HIT-3 is for insulation resistance and DC absorption current tests of coils with high-voltage Motors and Generators.
The measurable voltage range is from DC 500V to max 10kV.
DAC-HIT-3 automatically performs Polarization Index (PI) tests or Leak Index (LI) tests at setting voltages according to the mode selection, and the test result is stored into the memory.

DAC-LAS-2

DAC-LAS-2 is for measuring the resistive leak current of a zinc oxide surge arrestor (gapless) at the ground wire.
In general, the leak current of a surge arrestor is the combination of a resistive current, in phase with the applied voltage, and a capacitive current, in 90-degree lead. Especially the resistive current is said to be an important factor for detecting the deterioration of surge arrestors.. By simply clamping around the ground wire of the arrestor with the jaw of the current clamp CT, the set detects the leak current and can measure only the resistive current separated from the leak current.
