Sealable protection cover for core balance transformers
|Description||Sealable protection cover for core balance transformers|
The installation of protection or signalling resources such as earth leakage protection relays involves the use of core balance transformers.
Active conductors pass through the aperture of the core balance transformer, the differential summation of vector currents which enables the detection of leakage currents.
