Product Description

General Information

DC System Ground Fault Locator is to find the insulation fault of Voltage level 48V,110V,220V DC system such as indirect grounding,non-metal grounding,Loop grounding , positive and negative grounding, positive and negative balance grounding,AC into DC Fault, multi-point grounding.

Portable DC ground locator with High resolution sensor unit perform the acquisition of leakage current for grounding point of DC system . It can immediately measure and locate the grounding insulation impedance within 600KΩ at 220V voltage level to solve the insulation fault in DC system.
 

Features

1. Grounding voltage measurement, the instrument can measure the voltage of positive to grounding,voltage of negative to grounding and system voltage to realize the monitoring of 0-300V voltage .
2. System insulation impedance measurement function,the instrument can measure insulation impedance of positive to grounding , insulation impedance of negative to grounding , which can measure 0-999KΩ range .
3. Detection function of AC fleeing into DC,  the instrument can judge the fault of AC fleeing into DC in DC system and measure the voltage value fleed into AC in DC system. AC voltage measurement range is 0-280V.
4. Brand insulation impedance measurement Function. The instrument can measure the insulation impedance of positive and negative to the ground at each brand .
5. Fault Point Location function of brand grounding.
6. The instrument can be used as high accuracy current meter. The resolution of current measurement can be up 0.01mA
7. Grounding Detection function without signal , the instrument can locate the fault point unconnected the signal.
8. Direction Display Function . The instrument can indicate the grounding direction to user by a direction arrow.
9. Insulation Index Analysis Function, The instrument can indicate the insulation index of one detected brand route.
10. Waveform curve display function.  The screen can display the current change of detected brand route in waveform curve.
