Cable Distance Measurer

Power cables are often buried underground, unseen and untouchable. In the event of a fault, locating it is extremely difficult, often taking several days, even up to two weeks. This not only wastes a great deal of manpower and resources but also results in unquantifiable losses due to power outages. With the help of modern, innovative power cable fault testing equipment, fault points can be quickly located and the fault rectified promptly, restoring power supply.

 1.1 Product Introduction

The Distance Measuring Instrument for Power Cable Faults (hereinafter referred to as the Measuring Instrument) utilizes advanced electronic testing technology and single-chip microcomputer technology, integrating both low-voltage pulse reflection and pulse current testing methods, suitable for precise detection of various types of faults in power cables, such as high resistance, corona discharge, broken conductors, and low resistance..Accurate Distance Measurement.

  The low-voltage pulse reflection method is used for measuring the distance to low-resistance and open-circuit faults in cables, as well as for measuring the lengths or wave velocities of various cables. The pulse current method is divided into two testing methods: the impulse high-voltage flashover method and the direct current high-voltage flashover method, which are respectively used for measuring the distance to high-resistance and flashover-type faults in cables.

1.2 Product Features

● Combining low-voltage pulse reflection and pulse current testing methods, the system can detect faults such as open circuits, low resistance, high resistance, and flashovers.

Highly intelligent. Capable of automatically identifying whether a fault point is discharging and calculating the fault distance automatically.

● Utilizing current sensors to measure pulse current signals passing through the ground wire, compared to the traditional flash tester's method of measuring pulse voltage signals using resistive-capacitive voltage dividers, this approach offers simpler and more convenient wiring. Additionally, isolating the instrument from the high-voltage circuit electrically enhances safety.

● High testing accuracy, with a range less than1KmAt present, the testing accuracy is less than ±1mIn a range larger than1KmAt the moment, the test accuracy is less than.0.5％。

● Utilizing Chinese menu technology, easy to master and use.

● Featuring large screen LCDs with backlighting functionality.

● Utilizes rechargeable lithium-ion batteries with automatic charging management.

● Compact and lightweight, easy to carry.
