At present, the core problem of DC power supply ground fault search in power system is large field interference. Measured under different DC power supplies and different working conditions, poor anti-interference, leading to misdetection and misjudgment of many products, this is the biggest shortcoming of this series of products, but also the most common phenomenon.
The reason why our products can quickly gain a foothold in this market is because they successfully solved the interference problem. The portable DC ground fault finder is developed and produced with phase advance processing technology and data transfer algorithm technology. This product is between the online and portable types. The use method is portable and the performance is online. The instrument has the characteristics of high detection sensitivity, strong anti-interference ability, small size, light weight and convenient use. When looking for a ground fault in the DC system, there is no need to disconnect the power supply, and the grounding point can be located. The instrument can detect the grounding resistance and grounding direction of the DC system, providing a reliable and high accuracy detection instrument for the detection and location of the ground fault of the power DC system.
