  • How to test for short circuits in high-voltage distribution boxes

    How to test for short circuits in high-voltage distribution boxes

    The most common method for detecting shorts involves measuring the resistance between two points using the multimeter's ohmmeter function. A low resistance reading indicates a short circuit. At the high-power testing laboratory Berlin, the switching capacity of high and medium-voltage equipment is tested in terms of thermal stress and dynamic short-circuit performance, opening, breaking, and insulation capacity after short-circuit breaking, and operational behavior. Every opportunity presents a chance for an accident to. The ABB Testing Laboratories in Ratingen (Germany) are PEHLA-accredited and have over 60 years of type testing experience of low and medium voltage switchgear and controlgear. They conduct high-power, high-current, high-voltage, mechanical or en-vironmental testing for customers either in the lab.
