489-P5-HI-A20-E-H 发电机管理继电器

489-P5-HI-A20-E-H is a generator management relay manufactured by GE Multilin for the 489 series. This relay has 5 A phase CT secondary. HI control power supply is 90-300 VDC, 70265 VAC, 48-62 Hz. The analog output on this relay is 4 to 20 mA. The relay has a larger LCD enhanced display than the base display. Conformal coatings for harsh environments protect the unit from chemicals. Output status LED indicators include :1 Trip, 2 Auxiliary, 3 Auxiliary, 4 Auxiliary, 5 Alarm, and 6 Service. Generator status LED indicator including circuit breaker off, circuit breaker closed, stator heat, negative. Sequence, ground, loss of field, VT failure, circuit breaker failure. 489 Status LED indicators include 489 In Service, Setpoint Access, Computer RS232, Computer RS485 / Auxiliary RS485, and Alt "Setpoints", "Reset Possible" and "Message".

Accessories for the generator management relay include EnerVista 489 setup software, SR 19-1 panel, SR 19-2 panel, SCI module, Phase CT, HGF3, HGF8, HGF8, 489 1/8-inch collar and 489 3-inch collar. Metering features include user programmable analog inputs, speed (RPM) vs. critical phase inputs, RTD, power factor, frequency, MW, Mvar, ±MVarh requirements, apparent power and MVA requirements, actual power, MW requirements, MWh, current (phasor), amperage requirements, and voltage (phasor). Additional features of the relay include flash memory for easy firmware upgrades, simulation, VT fuse failure, trip coil supervision, circuit breaker failure, and an outlet box for maintenance and testing.
