ETCR2800C Earth Resistance On - line Detector is high-tech product that our company has devoted to "grounding resistance detection technology research" for more than ten years, specially design and manufacture for online monitoring grounding down lead connection status, circuit grounding resistance and metal circuit connection resistance. ETCR2800B is closed loop structure, convenient and efficient. On-line testing, non-contact measurement, grounding wire pass through the perforation of the detector, definitely not influence grounding for lightening effect and normal operation, real time on-line testing. Use by RS485 wire communication or GPRS wireless communication data transmission, realize remote online monitoring .Detector built-in sensor and circuit board, completely sealed, ensure high-accuracy, high stability and high reliability of long time on-line monitoring at field and indoors.
ETCR2800C Earth Resistance On - line Detector suitable for transmission line tower grounding; Meteorological lightning protection grounding; Petrochemical grounding; Communication grounding; Substation grounding; Railway facilities grounding; Construction warehouse grounding; Metal circuit resistance; Electrical equipment grounding etc.
ETCR2800C Earth Resistance On - line Detector could set up wired and wireless network system. Wired network system through RS485 communication protocol to transmit data, build up by the detector, 【communicator, monitoring software, power adapter, computer(above equipment need the user provide and secondary development) 】and other components; Suitable for short-distance ground resistance monitoring. Wireless network system through GPRS communication protocol to transmit data , build up by the detector(built-in GPRS transceiver module), 【SIM communication card, monitoring software, power adapter, computer(above equipment need the user provide and secondary development)】 and other components for long-distance ground resistance monitoring. Wired network system is suitable for monitoring within 1,500 meters distance, wireless network system is not subject to distance restrictions.
