Major Features and Benefits: –

The SEL-710-5 Motor Protection Relay provides an exceptional combination of protection, monitoring, control, and communication in an industrial package.

Standard Motor Protection and Control Features. Protect low- or medium-voltage three-phase motors, and variable frequency drive (VFD) fed motors, with an enhanced thermal model that includes locked rotor starts, time-between-starts, starts-per-hour, antibackspin timer, load loss, current unbalance, load jam/stalled rotor, phase reversal, breaker/contactor failure, positive temperature coefficient (PTC) thermistor over temperature, phase, negative-sequence, residual ground instantaneous, and inverse-time overcurrent elements. Implement load control, star-delta starting, two-speed control, and forward/reverse start control. Other standard features include broken rotor bar detection, rotor slip calculation, virtual speed switch, motor coast time, undervoltage, overvoltage, inverse-time over- and undervoltage elements, underpower, reactive power, phase reversal, power factor correction, frequency, loss of potential, breaker failure protection, incipient cable fault detection, asset monitoring capabilities, and RTD-based protection. As many as 10 RTDs can be monitored using an internal RTD card or as many as 12 RTDs using an SEL-2600 RTD Module with the ST® option.

Optional Synchronous Motor Protection and Control. Use the SEL-710-5 with an optional synchronous motor/differential card (SYNCH/3 DIFF ACI) that provides starting control, power factor or reactive power closed loop regulation control, and loss-of-field, out-of-step, loss-of-synchronism (pull-out), field resistance, field voltage, and field current protection elements.

Optional Differential Protection. Use the SEL-710-5 with optional current differential protection available with fourchannel arc-flash card (4 AFDI/3 DIFF ACI) or synchronous motor protection and control card (SYNCH/3 DIFF ACI).

Optional Arc-Flash Protection. Use the SEL-710-5 with optional four-channel fiber-optic arc-flash detector inputs and differential protection elements (4 AFDI/3 DIFF ACI) or the eight-channel fiber-optic arc-flash detector inputs (8 AFDI). Settable arc-flash phase and neutral overcurrent elements combined with arc-flash light detection elements provide secure, reliable, and fast-acting arc-flash event protection. ➤ Operator Controls. Start and stop the motor easily with eight programmable front-panel pushbuttons, each with two tricolored LEDs. Also, the SEL-710-5 provides 32 local and 32 remote control bits to help manage relay operations.

Integrated Web Server. Log in to the built-in web server to view metering and monitoring data and download events, Sequential Events Recorder (SER), etc. Also, use the server to view relay settings and to perform relay firmware upgrades.

Relay and Logic Settings Software. Reduce engineering costs for relay settings and logic programming with ACSELERATOR QuickSet® SEL-5030 Software. Tools in QuickSet make it easy to develop SELOGIC® control equations. Use the built-in phasor display to verify proper CT polarity and phasing.

Metering and Asset Monitoring. Eliminate separately mounted metering devices with built-in metering functions. Analyze Sequential Events Recorder (SER) reports and oscillographic event reports for rapid commissioning, testing, and post-fault diagnostics. Monitor the health of your asset and accompanying devices using these asset monitoring capabilities:

  • Vibration Monitoring
  • Motor Monitoring Using Fourier Analysis
  • Broken Rotor Bar Detection
  • Motor Start Report
  • Motor Maintenance Report
  • Motor Operating Statistics
  • Motor Start Trending
  • Load Profiling
  • Incipient Cable Fault Detection
  • Molded Case Circuit Breaker Health
  • Breaker Monitoring

 

Front Panel HMI. Navigate the relay HMI through the use of a 2 x 16-character LCD or optional 5-inch, color, 800 x 480-pixel touchscreen display.

Additional Standard Features. Use other standard features, including Modbus® RTU, MIRRORED BITS® communications, built-in web server, load profile, breaker wear monitoring, 128 remote analogs, support for 12 external RTDs (SEL-2600), IRIG-B input, advanced SELOGIC control equations, configurable labels, and an SEL-2812 compatible ST fiber-optic serial port.

Optional Features. Select from a wide offering of optional features, including IEC 61850 Edition 2, Modbus TCP/IP, DNP3 serial and LAN/WAN, EtherNet/IP, Simple Network Time Protocol (SNTP), IEEE 1588-2008 firmware-based Precision Time Protocol (PTP), IEC 60870-5-103, PRP with dual Ethernet ports, 10 internal RTDs, additional EIA-232 or EIA-485 communications ports, and single or dual, copper-wire or fiber-optic Ethernet ports. Several analog and digital options are available. These include 4 AI/4 AO, 8 AI, 4 DI/4 DO, 8 DI, 8 DO, 3 DI/4 DO/1 AO, 4 DI/3 DO, and 14 DI. Conformal coating for chemically harsh and/or high-moisture environments is available as an option.

Language Support. Choose English or Spanish for your serial ports, including the front-panel serial port. The standard relay front-panel overlay is in English; a Spanish overlay is available as an ordering option
