These portable testers have been designed to be used in testing high voltage equipment in power engineering. Routine testing of the insulation and leakage is a necessary requirement for surge arresters, cable breakdown testing, capacitor charging and other laboratory use.

  • Machine Feature

    • Switched-mode technology utilizing pulse width modulation to control the output voltage accurately.
    • Voltage divider is an integral part of the tester with an surge limiting resistor.
    • Tester delivered in two sections: Control and HV unit. Each packed in a flight case for easy transportation.
    • Testers of over 200kV voltage, HV unit has adjustable legs to increase the equipment's stability.
    • Digital kilo voltmeter and µA/mA meters display the test voltage and leakage current.
    • Zero start up. Audible alarm and LEDs for breakdown and over voltage occurrences.
    • Small dimension. Low weight. Carried conveniently.
    • Discharge pole with limiting current impedance.
