Overview
Enviro Test Construct multiple portable DC grounding fault detector is developed and manufactured by using phase advance processing technology and data transfer algorithm technology. This product is between the two types of on-line and portable, the use method is portable, and the performance is on-line. The instrument has the characteristics of high detection sensitivity, strong anti-interference ability, small volume, light weight and easy to use. When finding the grounding fault of DC system, it is not necessary to disconnect the power supply, and the grounding point can be located. The instrument can detect the grounding resistance and grounding direction of DC system and provide a reliable and high accuracy detection instrument for the search and location of grounding fault in power DC system.
