Small Volume Earth Insulation Tester , Ground Resistance Tester Without Installation

Earth Fault Earth Insulation Test DC System Ground Fault Detector

PDF-3000A DC System Ground Fault Detector

Features

1. It is composed of signal generator and signal receiver. Signal generator is used to test bus line earth resistance, it acquires electricity directly from bus line without external AC power source or battery
2. One ground detector in common use for 24V,48V,110V,220V DC system
3. can pinpoint the ground fault, eliminate the interference of large capacitance, lock the location in the smallest area
4. 100% accurate
5. It applies to AC& DC looping current grounding, ring network power supply grounding, diode isolation power supply grounding, high resistance grounding
6. Locate one or multiple ground positions without installation, electrical cutting, and insulated pumping.
7. small volume, light weight and portable
