Resistor Tester

The Opening and Closing Type Ground Resistance Online Detector is the result of over a decade of our company's dedication to...Another high-tech product in the field of "Ground Resistance Testing Technology Research," meticulously designed and manufactured for online monitoring of grounding wire connections, loop grounding resistance, and metallic loop bonding resistance. The product features an open-close structure, allowing for easy and quick installation without the need to disconnect the grounding wire. Online testing, non-contact measurement, ground wire penetration, without affecting lightning protection grounding effects and facility normal operation, no need for self-inspection, real-time detection, and adoptionRS232、RS485Cable Communication orGSMWireless communication transmits data for remote online monitoring. The detector is equipped with built-in sensors and circuit boards, fully enclosed, featuring rainproof, dustproof, high and low temperature resistance, corrosion resistance, flame retardant, etc., ensuring high precision, stability, and reliability for long-term online monitoring in outdoor, underground mines, and indoor environments.

The Open/Close Type Ground Resistance Online Tester is suitable for grounding of transmission line poles and towers; underground mine equipment grounding; meteorological lightning protection grounding; petrochemical grounding; communication grounding; substation grounding; railway facility grounding; building warehouse grounding; metal loop resistance; and electrical equipment grounding, etc.

The Open/Close Type Ground Resistance Online Detector can be installed and used individually, or configured into a wired network system or a wireless network system. The wired network system operates through...RS232、RS485Data transmission via communication protocols, by the main communicator(Concentrator)The monitoring software, power adapters, computers, and other components are suitable for grounding resistance monitoring in close proximity or underground mines.
