Metering Solutions

SEL metering solutions offer leading power quality capabilities with exceptional revenue metering accuracy at an economical price. Combining SEL-735 Power Quality and Revenue Meters with SEL-5705 Synchrowave Reports helps you support system optimization by trending energy usage, identifying peak demands, and helping locate power quality disturbances. Industry standard communications deliver critical and historical information to virtually any communications system in substations, industries, or power plants.

We provide best-in-class solutions backed by a standard ten-year warranty, including hardware, reporting software, and mounting solutions. Our prewired solutions reduce shop and field time and provide a secure housing with plenty of room for accessories. And if you need assistance putting together a metering system, the SEL Engineering Services Metering Services team is ready to help.

Ensure Accurate Revenue Metering 

Exceed ANSI C12.20 0.1 accuracy class and IEC 62053-22 0.1 S accuracy class requirements with bidirectional, full four-quadrant energy metering for generation, interchange, transmission, distribution, or industrial applications. Many new metering installations, such as distributed generation, operate over a wide current range. The SEL-735 accurately reports energy even in the presence of harmonics and distorted waveforms and provides high accuracy over an extended operating range.

Log Profile Data

Collect billing data with a simple-to-use load profile recorder that captures years of data. Independent load profile recorders in the SEL-735 allow simultaneous meter and power quality logging of up to 512 analog channels for up to 20 years. SEL meters trend averages, minimums, maximums, changes, and snapshots at a rate as often as every three seconds.

Measure and Report Reliable Power Quality Indicators 

Ensure precise and reliable measurements with IEC 61000-4-30 Class A power quality compliance. The SEL-735 measures harmonics, interharmonics, flicker, power factor, voltage disturbances, K-factor, and other key power quality indicators. It can record 10,000 oscillography events with programmable trigger conditions, such as a voltage interruption. Enabled from the factory, the voltage, sag, swell, and interruption (VSSI) recorder time-stamps voltage excursions with up to 1 ms resolution and records indefinitely using an adaptive sampling rate.

Streamline Commissioning, Testing, and Daily Use 

View real-time metered quantities, phasor diagrams, voltage and current waveforms, and more with the SEL-735 touchscreen meter’s intuitive interface and always-on display. Quickly navigate between applications and folders, set complex passwords, and configure settings without connecting a laptop. Speed up accuracy testing by visualizing test pulses, accumulated energy, and instantaneous signals.

Organize, Optimize, and Visualize Site-Wide Data 

Meter Reports retrieves site-wide data and displays it for analysis. The software generates charts and reports and can help you manage data to drive planning, operations, and billing decisions. SEL services or other third-party services can use SEL-5230 acSELerator Database API software to provide integration for customized reporting, sending data to third-party software, or exporting data into third-party databases.

Retrofit Installations Easily

Reduce wiring and connections by replacing socket meters with the SEL-735. Standard connector blocks make interconnections simple. We also offer prewired solutions that save time and provide a secure housing, including room for accessories. You can mount an SEL meter on a wall, in an indoor enclosure, outdoors, or on a swing bracket, panel, cabinet, or rack. For a novel draw-out solution, we also offer an Easily Extractable Meter (EXM) option.
