Product nickname

Loop grounding resistance online monitoring, metal loop connection resistance online monitoring, grounding status monitoring; grounding wire, metal cable anti-theft monitoring.

Product Introduction

Xtester-ETCR2800 non-contact grounding resistance online tester is specially designed and manufactured for online monitoring of the connection status of grounding down conductors, loop grounding resistance, and metal loop connection resistance. On-line test, non-contact measurement, grounding wire through the heart, no need for self-test, real-time detection. Provide RS485 (support MODBUS-RTU communication protocol). The detector is composed of sensors and circuit board modules, which is suitable for secondary development and integration by users. It is suitable for grounding of transmission line towers; underground mine equipment grounding; meteorological lightning protection grounding; petrochemical grounding; communication grounding; substation grounding; railway facilities grounding; building warehouse grounding; It can also be used for anti-theft monitoring of grounding wires and metal cables.

      Xtester-ETCR2800E is a small-diameter sensor with small size and light weight, suitable for installation in places with limited space. It can be installed and used individually, or it can be used as a wired network system or a wireless network system.
