    Wiring Diagram

    High voltage tester wiring diagram


    Q1: What is the high voltage tester used for?
    A1: A high voltage tester is widely used in substations, power plants, fire departments, industrial and mining enterprises, electrician maintenance departments for power detection and field electrician work, etc.

    Q2: What is a high-voltage electroscope?
    A2: High-voltage electroscope is a tool used to check whether high-voltage lines and power equipment are live, and is a basic safety tool commonly used in 
    substations. The high-voltage electroscope is used to check whether the line or equipment is charged, the purpose is to ensure personal safety.

    Q3: How to divide the high voltage tester level?
    A3: According to the applied voltage level, a high voltage tester can be divided into: 0.1-10KV detector, 6KV, 10KV detector, 35KV, 66KV detector, 110KV, 220KV detector, and 500KV detector.

    Tips: How to detect high voltage with a wireless high voltage detector?

    When the bare conductor voltage exceeds 60kV, non-contact power testing, the detector gradually closes to the wire, without touching the wire to complete the power test. For the bare wire below 60kV, the detector can be hung on the line contact test. Whether it is zero line, fire line, ground, high-voltage transmission line, or metal conductor, as long as there is electricity, maybe direct transmission of electricity, may also be insulation damage caused by leakage, the full intelligent detector can sense its electric field, and emit a beeping sound, the stronger the electric field near the wire, the beeping sound more urgent, warning of electricity.
