About the G60-G03-HCH-F8L-H6C-M8N-P6C-U6C-W6C

Offering versatile protection elements for total generator management and protection, General Electric Multilin’s G60-G03-HCH-F8L-H6C-M8N-P6C-U6C-W6C is a Generator Control System. It can serve medium to large generators driven by steam, gas, or hydraulics in addition to automated substation control systems and pumped storage generators operating as pumping motors.

In addition to its various metering and monitoring capabilities, some of the aforementioned protection elements include:

• Generator Stator Differential: This feature offers sub-cycle detection and clears stator phase faults at an accelerated rate. The relay employs complex algorithms to provide invulnerability to low current DC and high current AC saturation conditions.

• Field Ground Protection: This technology detects ground faults in the generator field winding, safeguarding the generator against major impairments caused by these faults. This function is associated with an internal module that works with the relay to identify these faults as they transpire.

• Out-of-Step/Power Swing: This feature ensures the blocking of the backup distant element during power swing conditions (in addition to other protections). This element can also be used to trip the generator if an unstable power swing is identified.

• Restricted Ground Fault: This element provides shielded coverage to the stator winding’s neutral point, a location in which the fault currents can fall below the pickup of the main stator differential element. 

These features reduce overall system downtime and prolong the life of the generator system, lowering long-term costs for users employing the G60-G03-HCH-F8L-H6C-M8N-P6C-U6C-W6C relay.
