FB28 Cable Fault Tester

    FB28 cable fault tester includes cable fault ranging unit, pathfinding and identification unit, high-voltage signal unit, fault location unit, a total of four units, can be applied to a variety of scenarios, such as farmland watering cable fault checking and repairing, highways, community property and landscaping green belts, street lamp cable maintenance, field power cables, factories, mines and enterprises and other scenarios.

• Ranging Unit:

1. Can be measured below 35KV level of all cables with high and low resistance faults, widely adapted. 

2. With high-voltage equipment with the traditional impact of high-voltage flashover method and low-voltage pulse method. 

3. Any high-resistance faults are presented in the simplest similar low-voltage pulse short-circuit fault waveform characteristics, very easy to read.

4. With user-friendly software and full Chinese menu. Key definition is simple and clear. Measurement method is simple and fast. 

5. The success rate of detecting faults, testing accuracy and testing convenience is better than any domestic testing equipment. 

6. Large LCD screen as a display terminal, the instrument has a powerful data processing capabilities and friendly display interface. 

7. With a very safe sampling of high-pressure protection measures. The test instrument will not die and be damaged in the impact high-pressure environment.

8. Built-in power supply, can be in the absence of power environment test cable open circuit and low resistance short circuit fault.

• Path Unit:

    Path unit is divided into transmitter and receiver, is based on the principle of reflection of electromagnetic waves in the transmission process and the principle of electromagnetic induction, combined with digital filtering, wireless reception, software control and design of high-tech products. The signal of the transmitter is directly applied to the target cable (blackout cable) by a direct line, i.e. the direct connection method. Detecting the path is one of the main roles of this instrument, different sites can choose a different way of applying the signal, the choice of priority is: direct connection. The reception and detection of the signal is not affected by the method of signal application, and the operation is the same.

• High Voltage Unit:

    Adopts single-chip computer to control the boosting voltage. Light weight, high output voltage, high power is its biggest feature, the whole instrument is about 15 kilograms, which greatly improves the portability of the field use, and say goodbye to the site of the heavy mobile. It can be used to do 35KV and below cable fault test high-voltage source, DC withstand voltage test high-voltage source, and can be used for energy storage impact discharge test after adding capacitor. Voltage regulation and automatic voltage stabilization function, with open-circuit, short-circuit automatic protection function. The output voltage value is high voltage direct-reading display, which can ensure that the voltage on the high voltage side can still be correctly displayed after the control switch is disconnected. High-voltage zero start, to ensure that the output high voltage from 0 start to 36kv. function perfect and reliable, the box using insulating materials, the operation is absolutely safe. Small size (43cm×38cm×23cm), light weight (15Kg), can work continuously for 4 hours.

• Fixed-point Unit:

    The PTR30 fixed-point instrument is equipped with first-class integrated circuits and amplifiers. Filters on the instrument's sound channel maximize the removal of interfering noise, while enhancing the sound generated by the arc. The LCD display shows both acoustic and magnetic pulses and the distance of the fault point from the probe test point. The instrument is composed of five parts: electromagnetic wave sensor, acoustic vibration sensor, CPU data processor, liquid crystal display and audio amplifier.
