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. 2.1.2 METERED QUANTITIES METERED QUANTITY UNITS OPTION Phase Currents and Current Demand Amps Motor Load × FLA Unbalance Current % Ground Current Amps Input Switch Status Open / Closed Relay Output Status (De) Energized RTD Temperature °C or °F R Backspin Frequency Hz B Phase/Line Voltages Volts M Frequency Hz M Power Factor lead / lag M Real Power and Real Power Demand Watts M Reactive Power and Reactive Power Demand Vars M Apparent Power and Apparent Power Demand VA M Real Power Consumption kWhrs M Reactive Power Consumption/Generation ±kvarhrs M 2-2 369 Motor Management Relay GE Power Management 2.1 OVERVIEW 2 PRODUCT DESCRIPTION 2 2.1.3 PROTECTION FEATURES ANSI/IEEE DEVICE PROTECTION FEATURES OPTION TRIP ALARM BLOCK START 14 Speed Switch • 27 Undervoltage M ••• 37 Undercurrent / Underpower /M • • 38 Bearing RTD R or RRTD • • 46 Current Unbalance • • 47 Voltage Phase Reversal M • 49 Stator RTD R or RRTD • • 50 Short Circuit & Backup • 50G/51G Ground Fault & Ground Fault Backup • • 51 Overload ••• 55 Power Factor M • • 59 Overvoltage M • • 66 Starts per Hour/Time Between Starts • 74 Alarm • 81 Over/Under Frequency M • • 86 Lockout • 87 Differential Switch • General Switch • • Reactive Power M • • Thermal Capacity • Start Inhibit (thermal capacity available) • Restart Block (Backspin Timer) • Mechanical Jam • • Acceleration Timer • Ambient RTD R or RRTD • • Short/Low temp RTD R or RRTD • Broken/Open RTD R or RRTD • Loss of RRTD Communications RRTD • Trip Counter • Self Test/Service • Backspin Detection B • Current Demand • kW Demand M • kvar Demand M • kVA Demand M • Starter Failure • Reverse Power
