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.
Basic description:

• Current-calibrated busbar differential 
• Attracted armature design with simple and robust construction High impedance protection principle

Key customer 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
