Motor protection and management shall be provided by a digital relay. Protective functions shall include:

• phase overload standard curves (51)

• overload by custom programmable curve (51)

• I2t modeling (49)

• current unbalance / single phase detection (46)

• starts per hour and time between starts

• short circuit (50)

• ground fault (50G/50N 51G/51N)

• mechanical jam / stall

Optional functions shall include:

• under / overvoltage (27/59)

• phase reversal (47)

• underpower (37)

• power factor (55)

• stator / bearing overtemperature with twelve (12) independent RTD inputs (49/38)

• backspin detection

Management functions shall include:

• statistical data

• pre-trip data (last 40 events)

• ability to learn, display and integrate critical parameters to maximize motor protection

• a keypad with 40 character display

• flash memory

The relay shall be capable of displaying important metering functions, including phase voltages, kilowatts, kvars, power factor, frequency and MWhr. In addition, undervoltage and low power factor alarm and trip levels shall be field programmable.

The communications interface shall include one front RS232 port and three independent rear RS485 ports with supporting

PC software, thus allowing easy setpoint programming, local retrieval of information and flexibility in communication with

SCADA and engineering workstations.
