Product Description
Features
- Display of leakage current
- Wide range of settings
- Low burden
- Communication through USB & RS485(MODBUS)
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 atier the operating time. The relay output contacts are self reset type. TEST bution facilitates verification of relay contacts.
