Built With Experience

The easy-to-use touchscreen interface, which is already available in SEL-700 series protective relays, displays power system status at a glance without having to connect to a PC. It provides a one-line mimic display for control and monitoring and displays metered quantities, phasor diagrams, relay settings, event summaries, target statuses, and Sequential Events Recorder (SER) data.

What’s New

The SEL-735 with color touchscreen also includes:

  • A USB-C front communications port.
  • Real-time Wave View oscillography.
  • A default rotating display with voltage, current, power, energy, and more.
  • An accuracy test mode application and infrared test LED.

More Standard Features

Packaged features include:

  • Advanced power quality and recording.
  • Copper 10/100BASE-T Ethernet.
  • EIA-232 and EIA-485 serial ports.
  • IEC 61850 communications protocol.

Home Screen

Home View

With a simple tap, quickly access metered quantities, phasor diagrams, settings, and more.

Phasor Diagrams


Analyze the real-time voltages and currents in a power system during balanced and unbalanced conditions. This allows you to verify that the system wiring is correct during commissioning, see changes in system conditions as loads vary, and more.

Fundamental Metering

Fundamental Metering

Monitor the power and power factor in your system to measure system efficiency and the real-time load flow.

Energy Metering

Energy Metering

View the energy metering quantities imported and exported by the system. You can reset the energy values via the display and record the time and date of reset.

Test Mode

Test Mode

Speed up accuracy testing by visualizing test pulses, accumulated energy, and instantaneous signals. When in Test Mode, the SEL-735 freezes the billing quantities to isolate your test inputs from revenue billing.

Real-Time Oscilloscope

Wave View

Display cycle-by-cycle voltage and current waveforms in real time. The Wave View feature offers oscilloscope-like functionality, improving your awareness of system distortions and allowing you to troubleshoot power quality issues that can affect sensitive equipment.

Four-Quadrant Metering

Four Quad Metering

Monitor power and energy accumulation in each delivered/received, lagging/leading quadrant for bidirectional metering. Four-quadrant VAR metering allows you to verify system efficiency.

Large Three-Line Display

Three Line Display

Continuously monitor all three power system phases from a distance. Customizable screens provide useful defaults, large fonts, and numerous choices for analog quantities.
