Fault Locator cable tester DC System Grounding Fault Locator

  Overview

Nowdays, the core problem of electric power system DC power supply's ground-fault trouble shooting is that the interference is big on the site. The measure result under different DC power supply and different working condition is poor anti-jamming which leads to misdetect and misjudgement. This is the biggest drawback and the most common phenomenon of this series of product. However our product successfully resolved the interference problem so that we can have a foothold on the market. HZGZ-IV portable DC ground-fault locator (split type) adopts thetechnology of sine signal phase advance and data transfer algorithm. It’s portable and it offers an online performance. The instrument has a characteristic of high detection sensitivity, strong anti-jamming capability, small volume, light weight and it’s easy to use. When seeking DC system ground-fault, you don't need to break the power to locate the grounding point. The instrument can detect DC system's grounding resistance and its grounding direction, which makes it a reliable and high accuracy instrument for electric power system's ground-fault searching and locating.

 Main features of the instrument

1. The instrument is consist of analyzer and ground-fault locator, the analyzer (which can be used to detect bus-bar grounding resistance) can access to the power from bus-bar directly andit doesn't have to access AC power system or battery, so it’s more convenient.

2. 110V/ 220V DC system share the same DC grounding detector.

3. It can completely locate DC system's ground-fault and get rid of the interference of the large distributed capacitance from the site and also accurately lock the grounding area in a small range.

4. It applies to grounding caused by the string of AC or DC, ring network power supply grounding, diode isolated power supply grounding and high grounding resistance.

5. You can fast and accurately find single point or multipoint of grounding positions without installment, power break or shake the insulation, the result can be 100 percent accurate.

6. You can realize automatic detection by just open and close the current clamp’s jaw opening, the instrument can also prevent misinformation.

7. Luxury outer packing; Easy to carry.
