Series:
The relay belongs to the 489 series of GE Multilin.
Features:
Protection function: It can monitor various operating parameters of the generator, such as voltage, current, frequency and power, etc., and trigger corresponding protective actions when these parameters exceed the safety range, such as disconnecting the power supply or starting the alarm to prevent damage to the generator.
Control function: In addition to the protection function, it can also be used to control the operation of the generator, such as starting, stopping and switching, according to the preset logic or external signals to control the operating state of the generator to ensure the stable operation of the power system.
Programmability: Usually has a programmable function, the user can set the parameters and logic of the relay according to the specific application needs, so that it can adapt to different generator systems and operating environments.
Functions:
It plays a key role in the generator management system to ensure the safe, stable and efficient operation of the generator by monitoring and controlling the operating parameters of the generator. It helps to detect potential problems in a timely manner and take appropriate measures to prevent damage or failure, thereby improving the reliability and service life of the generator.
