The manual explains the functions, technical parameters, installation steps and fault‑detection principles of the PMF560 cable fault indicator.
The PMF560 cable fault indicator monitors cable lines in 6~35 kV power systems, providing rapid and accurate location of short‑circuit and ground faults. It consists of short‑circuit and ground‑fault detectors, a communication host, a power‑CT and an optional panel indicator, all capable of remote telemetry and communication.
The document details the system architecture, basic functions of each detector, technical specifications, communication methods (fiber, RS‑232, GPRS), and step‑by‑step installation guidelines for the detectors, communication host and power‑CT, including wiring, mounting and safety precautions. This manual is written in Chinese.
