Multilin MCAG
High Impedance Bus Differential Relay
​
MCAG relays provide high-speed differential protection for various types of power system plants Including generators, reactors, busbars, motors and the individual windings of power transformers. The relays provide current-calibrated busbar differential and have an attracted armature design with simple and robust construction.
​
Key features :
​
-
High thermal withstand - improved when used with the stabilising resistor
-
Long service history, over 43,000 delivered since 1984
-
Design pedigree coming from over a million auxiliary relays in-service
Key benefits :
​
-
High stability during through faults Operation is fast and reliable (25ms at 5 x setting)
-
Easy integration into 4U height MIDOS rack schemes
-
Highly-tuned to the fundamental to prevent spurious operation
Main characteristics :
​
-
3 element relay supplied in a 30TE (size 6 inch) case
