Product Description
Features
- Bar graph indication of leakage current
- Remote reset and test facility
- Wide range of setings
- Low burden
Application
The relay provides time graded earth leakage protection for generators, transformers, capacitors, feeder etc
Principle of Operation
The relay provides earth leakage protection for power systems. The relay operating time is determined by a programmable definite time delay. The relay measures the earth leakage current from the CBCT and if it exceeds the set threshold, the relay extends a trip signal after the operating
time. The relay output contacts are self reset type. TEST bution facilitates verification of relay
contacts.
