EATON Generator Relays
Eaton generator relays offer superior protection to generators against various faults and abnormal operating conditions. These multifunctional relays provide control and backup protection for medium to large-sized generators.
AWorking Mechanism
- When these Eaton relays detect an overvoltage condition, they activate the protection element designed to limit the voltage to a safe level.
- If these relays detect a loss of excitation, they initiate an automatic voltage regulator (AVR) response to restore the generator's field excitation.
Features
- Eaton generator relays provide complete metering, protection and control in a single compact case to reduce panel space.
- Their integral test function reduces maintenance time and expense.
- These relays have removable terminals to install wires easily.
- Their zone-selective interlocking function improves coordination and tripping time compared to a traditional bus differential scheme.
Frequently Asked Questions
What are some common challenges associated with generator protection?
Common challenges associated with generator protection include the complexity of the protection system, the need for coordination with other protection systems and the potential for false trips or nuisance alarms. Proper commissioning, testing and maintenance can help mitigate these challenges.
Can generator protection relays be integrated with other protection systems?
Yes, they can be integrated with other protection systems, like feeder protection & substation automation systems, to provide a comprehensive and coordinated protection scheme.
How to maintain these relays?
Generator protection relays can be maintained by periodic inspection, functional testing and calibration.
