Description

The GE 469-P5-HI-A20-E-H is a type of protective relay manufactured by General Electric (GE). Protective relays are devices that are used in electrical power systems to detect abnormal conditions, such as overcurrent or under/overvoltage, and to isolate the affected equipment from the rest of the system to prevent damage or failure. The GE 469-P5-HI-A20-E-H relay is a member of GE's Multilin 469 family of relays, which are designed to provide comprehensive protection and monitoring for power systems. This particular model is a high-impedance differential relay, which means it is primarily used to protect transformers and generators against internal faults. The "469" in the name refers to the family of relays, the "P5" indicates that it is a high-impedance differential relay, the "HI" refers to the high-impedance characteristics of the relay, and the "A20" indicates that it has 20 current inputs. The "E" indicates that it has an Enhanced Display, and the "H" indicates that it is conformally coated.
