Relay Test Block : ERMLG01 & Test Plug : ERMLB01
ERMLG01 Test Block provides facilities for monitoring and secondary injection testing of Power system protection schemes in conjunction with the multi fingered test plug ERMLB01. The ERMLG01 Test block eliminates the need to disturb protective system wiring during secondary injection testing. These were developed in record time, initiated on a fast track schedule and completed within a span of just two months.
The ERMLG01 Test block has 14 contacts and is housed in an Epsilon enclosure of E2 size.
The ERMLB01 Test Plug has 28 test sockets, each socket accepts 4mm test lead plugs, for testing of protection schemes. The ERMLG test block and ERMLB Test plug have been validated and successfully typed at Electronic Testing & Development Centre (ETDC), Bangalore. They have Undergone the Following tests:
- Impulse test - 5kV (IEC 60255-5)
- Dielectric test and Insulation Resistance (IEC 60255 - 5)
- Current withstand test - 20A continuously and 400A 1s.
- Vibration test - IEC 60255-21-1
- Humidity test - IEC 60068-2-3
- Atmospheric test - IEC 60068 -2-1 and IEC 60068-2-2
- Enclosure Protection test - IP 50 test - (IEC 60259)
