UHV-500 Cable Fault Location Detector-Catalog

Product catalog summary

Product Overview
The UHV-500 Cable Fault Detector by Wuhan UHV Power Technology Co., Ltd. is designed to ensure the smooth operation of wired communication and power transmission by detecting and rectifying cable line faults promptly. It is a high-tech, intelligent instrument that combines advanced electronic technologies with computer technology for comprehensive cable fault detection.

Part 1: Cable Fault Distance Testing

Features: The device offers safe, rapid, and accurate fault testing using low-voltage pulse and high-voltage flashover methods. It provides high testing accuracy with a 100MHz A/D sampling rate and a reading resolution of 1m. The instrument is highly intelligent, displaying results on a large LCD screen with a full Chinese menu. It includes waveform storage, dual-trace display, and waveform expansion functions.
Parameters: Suitable for testing various power cables (1KV～35KV), telephone cables, and more. It has a maximum testing distance of 15Km, a detection blind zone of 1m, and operates under specific temperature and humidity conditions.

Part Two: Cable Route Locator
The locator consists of a transmitter, receiver, audio probe, and headphones. It features high receiver sensitivity, low static drift, and strong anti-interference capability. The transmitter power is >15W with a signal frequency of 16KHz.

Part Three: Locating the Fault Point
The principle involves using high voltage to discharge the fault point, converting the vibration sound into an electrical signal for detection. The process includes measuring the distance to the fault point and using a locator for precise location.

Pulse Capacitor
Features a fully sealed metal casing, suitable for various applications like inrush current generators. It operates within a temperature range of -40°C to 55°C and has specific electrical parameters such as rated voltage and capacitance tolerance.

YDJ(Z)-3kVA/50kV Oil Type AC Test Transformer
This product is characterized by reliable quality, good stability, and the use of new insulation materials. It is compact and lightweight, with specific voltage and current parameters detailed in Table 1.

Wuhan UHV Power Technology Co.,Ltd. The instrument consists of four parts: a transmitter, a receiver, an audio probe, and headphones, as shown in the figure. • High receiver sensitivity • Easy operation • Strong anti-interference capability • Built-in lithium battery powered and comes with a charger Test Principle We know that when a cable fault point is broken down by high voltage, the discharge will produce a loud vibration sound. Since the cable is buried very deep, it is not easy for the human ear to hear. At this time, the weak vibration signal is converted into an electrical signal by a...
