Operation |
| |
The relay senses the Earth leakage
current for any equipment like L.T. Panels, Switch boards, Generators,
Transformers, Motors etc. These leakage current if continues
can cause insulation breakdown resulting Earth fault, which
results in to loss of damage to equipment. The PROTIME Earth
leakage relay senses leakage current through CBCT and energizes
relay when current goes out of the range selected on the dial.
The relays are provided with user settable (0-10sec) time delay.
The CBCt is connected externally with the Bus-bar or cable carrying
load current passed through it. |
