  • Description

    The high voltage DC tester is an universal high voltage tester. It is extremely robust, but also lightweight, compact and easily portable. Thanks to an internal rechargeable battery the high voltage DC tester enables mains-independent testing. Capacitive loads, such as shielded power cables, will be properly and automatically discharged in case of an error or at the end of testing time by the integrated discharge device. Key switch, switch-on interlock and a protective ground circuit ensure maximum safety.
    Features:

    • Easy operation
    • Robust construction, low weight
    • Mains-independent by internal rechargeable battery
    • Integrated timer, 1 … 30 min
    • Integrated discharge device
    • Internal battery charger with deep discharge protection
    • Voltage measurement direct at HV output
    • Output short-circuit-proof
    • Protective ground circuit

    Fields of application:

    • Testing at re-commissioning of cable systems after maintenance and repair
    • Testing of newly installed cables an cable joints before commissioning
    • Voltage testing at cable sheath
    • Testing of electrical equipmen
