Product Overview
Precision Fault Location
This Cable Fault Location Bridge is a specialized instrument designed for accurate fault pre-location in high, medium, and low voltage power cables ranging from 380V to 220KV. Utilizing the bridge balance method, it offers a blind-zone-free testing experience, making it highly effective for short cables and difficult-to-locate high-resistance breakdown points. Its robust design ensures reliability for industrial maintenance and utility applications.
