Comprehensive Power Cabling Fault Detection System

Comprehensive Power Cabling Fault Detection System

MOEORW-WLG310 is a professional-grade comprehensive power cable fault detection system that provides one-stop coverage of the entire process of fault diagnosis, ranging, location positioning, and path detection. It integrates multi-method ranging, acoustic-magnetic synchronous location positioning, and active/passive path detection functions, supports waveform storage, online communication, and can be equipped with GNSS positioning.

With core advantages such as 400MHz high-speed sampling and 0.1m high precision, dual operation modes make it easy to use, long battery life and high protection, stable operation in complex outdoor scenarios, and it is widely applicable to cable fault diagnosis, daily inspection and project acceptance in fields such as power, municipal, mining, and communications.

The MOEORW-WLG310 Power Cable Fault Comprehensive Detection System is a complete solution covering cable fault diagnosis, distance measurement, precise location, path detection, and cable identification. It is compatible with all fault types of power cables of various voltage levels, including low resistance, short circuit, open circuit, high resistance, and flashover.

The system consists of core equipment such as a fault rangefinder, a pinpointing device, a high-voltage signal generator, a path detector, and a multi-pulse coupler. These components work together to achieve a closed-loop detection process from fault diagnosis to precise location. It incorporates three ranging methods: low-voltage pulse, pulse current, and multi-pulse, with real-time sampling up to 400MHz and ultra-high ranging accuracy of 0.1m. Combined with acoustic-magnetic synchronous pinpointing and active/passive path detection technologies, along with practical functions such as background noise reduction, an electronic compass, automatic calibration, and intelligent gain adjustment, it can achieve accurate detection even in complex environments.

The equipment features a high-brightness, sunlight-readable color screen, supports both touch and mechanical button operation, has a built-in high-capacity lithium battery that can work continuously for over 10 hours, and also features waveform storage, computer connectivity, and IP65 protection. It is easy to operate, highly portable, and widely applicable to cable fault diagnosis in the power, municipal, and communications industries, significantly improving fault handling efficiency.
