This device can test insulation resistance (such as transformer, switchgear, lead, motor) of different modules in one system, to insulate and repair failure components.
Before power on the system, using insulation test to verify if it is good to improve system performance. Insulation test is to find manufacturing process problems and equipment fault which can not be found before failure happened.In EU,this test is compulsory,even to civil system.
- Voltage output GD2000D(250V/500V/1000V/2500V/5000V).Resistance range 0-200GΩ.
- Two modes display insulation resistance.
- Auto-calculating absorptance and polarization index.
- Friendly operation, continuous saving 19times measurement results.
- Auto-discharge residual high voltage after test is over.
- AC/DC power supply, with rechargeable battery or AC adapter.
- Strong anti-interference ability, stable and reliable reading.
- Portable design, suitable for wild work.
- Short-circuit current ≥3mA, ideal equipment for testing insulation resistance of Large transformer, inductor, generator, HV motors, electric capacitor, cables and surge arrester.
