Schneider MiCOM P721 High Impedance Differential Protection Relays

Schneider Micom P721 Relay high impedance differential protection series provides high impedance differential protection for generators, reactors, motor and busbar applications. Models available: MiCOM P721, MiCOM P723
Features
MiCOM P721 also offers the same application benefits as traditional high impedance electromechanical protection schemes, it combines the added benefits of numerical technology to provide advanced communications, event records, fault records, disturbance records and ancillary protection features.
Combined with the MiCOM P79x, a standalone metrosil and resistor unit, it provides simplified scheme engineering for single or three-phase differential applications.

Standard Manufacturers Warranty: 2 years

Schneider Micom P721 Relay Benefits:

Numerical High Impedance Relay

• Simple scheme engineering
• Reliable algorithm – stable for through fault and fast trip for internal fault
• Supervision functions included in the same protection box
• Set by current or voltage
• Numerical relay features

Applications
P721 offers reliable protection for busbars, transformers windings, generators, reactors and motors. P721 is suitable for restricted earth fault (REF) or balanced earth fault (BER) applications. P723 is suitable for busbar and machine phase differential protection.
