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
