MMLB / MMLG
Designed as part of the Midos range, these test blocks offer facilities for monitoring and secondary injection testing of any power system protection scheme when used with the multi-fingered test plug type MMLB 01.
​
The MMLG test block carries 14 circuits, each of which is brought out to separate pairs of terminals at the rear of the case.
​
Each circuit comprises a pair of internal contacts which are normally sprung together to complete the circuit link through the block when the associated protective equipment is in normal service.
​
Insertion of the test plug type MMLB 01 open circuits the contacts which connect terminal pairs, allowing testing to proceed.
Key benefits :
​
-
Test block can be mounted adjacent to Midos modular relays and systems
-
Test block removes the need to disturb protective system wiring for testing
-
Monitoring, isolation and secondary injection testing are simplified and quickly performed
