EPESOL’s generator protection devices provide most advanced and innovative solutions for the protection of generator assets. Generators are designed to run at a high load factor for a large number of years and permit certain incidences of abnormal working conditions so generator protection is critical in maintaining maximum uptime in the generating facility and providing vital protection of the generating unit. The generators must be provided with protective relays which, in case of a fault, quickly initiate a disconnection of the machine from the system and, if necessary, initiate a complete shutdown of the machine
