MFAC 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.
Providing high-speed differential protection, the MFAC relay is fast and reliable due to the simple electromechanical construction. It operates as a high impedance unit protection scheme and has a wide range of settings. Two versions for phase and earth fault protectionThe MFAC relay operates as a high impedance unit protection scheme, with settings determined by a series of resistors. The resistors are selected on a seven-way plug bridge.MFAC 14, a single element version, is applied only when earth fault protection is required. MFAC 34, comprised of three elements, provides both phase and earth fault protection. Wide setting range with a simple, robust designEnsuring high stability with through faults, MFAC relays benefit from a simple application technique. With tuned to rated frequency and a wide setting range, the MFAC has a robust and straightforward design. |
