The active conductors that. Thus leakage current if any will be dependent on the resistance value between respective terminals higher the resistance lower is the leakage. Carrying out the protection thanks to the residual current relays it is possible to measure the leakage current to earth. Earth leakage circuit breaker.

The new abb elr front panel residual current relays are tested for this purpose. The signals from the sensors are processed by the detector unit and leakage is detected. The dc earth leakage relay detects leakages from dc power systems by measuring differential current between the ve and ve current carrying conductors. Aa equals fn 50 hz and uaux 80 265 v ac dc.

Abb offers a comprehensive range of devices like rccbs rcbos rcd blocks earth leakage relays in order to cope with all the applications in residential commercial and industrial segments. Quick and fast wiring operation with cable and busbars. Quality international approvals available for each range. The relay senses the dc earth leakage current for any equipments like switch boards rectifiers battery chargers by sensing resistance between positive negative terminals of dc system earth.
