Quick and fast wiring operation with cable and busbars.
Dc earth leakage relay abb.
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.
Find out all of the information about the abb product.
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.
The signals from the sensors are processed by the detector unit and leakage is detected.
The new abb elr front panel residual current relays are tested for this purpose.
These relays work in conjunction with a separate external toroid.
