Product description
Product parameters
Reference standard: DL/T849.1-2004.
Features:
● Applicable to the distribution network of small current grounding system, detecting single-phase metallic grounding of overhead lines, grounding through arc, grounding through transition resistance, etc.;
● Positioning after the line is out of service, especially suitable for faulty lines with cable branches;
● Apply high voltage signal to reproduce the fault, the current signal is stable and easy to detect;
● The ultra-low frequency signal avoids the influence of the distributed capacitance of the system and can locate the high resistance fault;
● Transmitter high voltage start blocking function, output allows direct short circuit;
● The sensor uses high-sensitivity sensor, the opening design, no need to close, convenient for hanging on the line;
● Wireless communication between sensor and receiver is safe and reliable.
