HIGH-VOLTAGE CABLE GROUNDING CIRCUIT AC/DC IMPEDANCE LIVE DETECTION EQUIPMENT

New Products / New Technology

"The AC/DC impedance live-line testing equipment for high-voltage cable grounding loops is suitable for live-line diagnosis of high-voltage cable grounding states and precise defect location. The equipment adopts two testing methodsAC and DCwhich can be flexibly switched according to the induced voltage conditions of the sheath grounding system, ensuring convenient and safe operation. Compared to traditional passive methods such as infrared thermometry and circulating current detection, the AC/DC impedance live-line testing technology can test the grounding system impedance under live conditions, effectively screening for latent defects such as lead sheath cracking, copper busbar corrosion in grounding boxes, and outer cable sheath damage.
