Dc Dc System Ground Fault Tester/Ground Fault Locator
At present, the core problem of power system DC power supply grounding fault search is that the field interference is large, in different DC power supply and different working conditions measurement, most of the products will misdetect and misjudge, poor anti-interference. Sinusoidal signal phase processing technology and data transfer algorithm technology are used to develop and produce. This product is between the two types of fixed and mobile, the use method is mobile, the performance is online fixed, to find the DC system grounding fault, do not need to disconnect the power, can achieve ground location. The instrument can not only detect the grounding resistance value of DC system, but also detect the grounding capacitance capacity of DC system, which provides a suitable and reliable high accuracy detection instrument for the search and location of the grounding fault of power DC system.

Function and characteristics
1, 24V, 48V, 110V, 220V DC system share a set of DC ground detector.
2, can eliminate the DC system grounding fault, the field distribution of large capacitance interference, accurately lock the fault in a small range. 3, measurement accuracy :100%.
4, signal output power: < 0.15W, internal current limiting protection, no impact on relay protection, automatic, operating loop, safe use.
5, signal frequency stability: ±0.02HZ.
6, the use of "heart" design of the jaws, large and small line sharing, do not need to change the pliers.
7, can adapt to AC, DC series caused by grounding, ring network power supply grounding, diode isolation power supply grounding, high resistance grounding.
8, without installation, without power outage, without shaking insulation, you can quickly and accurately find a point or more ground position.
9, aluminum alloy packaging, easy to carry.
