The role of relay protection in generator sets is crucial for the proper and safe operation of the equipment, such as safeguarding the generator set, preventing equipment damage, maintaining a reliable and safe electrical supply. Generator sets typically include various types of protective relays that monitor different parameters and respond to abnormal conditions.
Key roles of relay protection in generator sets
Overcurrent protection: A relay monitors the output current of the generator set, and if the current exceeds the set limit, a circuit breaker trips to prevent damage to the generator set due to overheating and excessive current.
