SEL-735
Power Quality and Revenue Meter
The SEL-735 offers high-accuracy metering combined with detailed power quality analysis. With data available at their fingertips, operators can easily identify power system anomalies and mitigate their impact.For high-accuracy revenue metering applications, the SEL-735 exceeds ANSI C12.20 0.1 and IEC 62053-22 0.1 S accuracy class requirements over a wide current range. The SEL-735 maintains this accuracy through its entire service life, eliminating costs associated with field calibration. This makes the SEL-735 the premier choice for points of common coupling, interchanges, and critical loads.With optional continuous waveform streaming, the SEL-735 precisely samples and sends waveform data from the power system at 3 kilosamples per second (ksps).Accessories and Mounting Options

Ensure Accurate Revenue Metering
Exceed ANSI C12.20 0.1 and IEC 62053-22 0.1 S accuracy class requirements with bidirectional, full four-quadrant energy metering. 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. The SEL-735 will meet Class 0.1 accuracy requirements for its entire service life.Compensate for Errors in Instrument Transformers
Increase metering accuracy by compensating for instrument transformer errors. The SEL-735 interpolates six user-defined calibration points and corrects ratio and phase errors over the entire measurement range. You can decrease replacement and maintenance costs by compensating for each instrument transformer individually.Measure and Report Reliable Power Quality Indicators
Ensure precise and reliable measurements with IEC 61000-4-30 Class A power quality compliance. You can size feeders appropriately, safeguard equipment, and plan upgrades using power quality indicators for predictive maintenance. The SEL-735 measures harmonics, interharmonics, flicker, power factor, voltage disturbances, K-factor, and other key power quality indicators.Load 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. The SEL-735 can trend averages, minimums, maximums, changes, and snapshots at a rate as often as every three seconds.Stream and Record Waveform Data
The SEL-735 captures every disturbance in your power system. Optional continuous waveform streaming precisely samples voltage and current signals at 3 ksps and sends the data to SEL Synchrowave software for visualization.Record Voltage Sag, Swell, and Interruption (VSSI) Data
Enabled from the factory, the VSSI recorder time-stamps voltage excursions with up to 4 ms resolution and records indefinitely using an adaptive sampling rate. Settings include trigger thresholds from ±3 percent to ±100 percent of the actual value and an automatic recording duration dependent on the length of the voltage excursion.Streamline Commissioning, Testing, and Daily Use
View real-time metered quantities, phasor diagrams, voltage and current waveforms, and more with the intuitive always-on touchscreen 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.Bundle Hardware and Software
Automate data retrieval, quickly visualize data, and create custom reports with the enterprise data collection and reporting software bundle, which includes Synchrowave Reports software. This combination of hardware and software simplifies ordering and license management, eliminates base license fees, and allows utilities to incrementally purchase the software device license for that meter.

Minimize the cost of harmonic mitigation with continuous waveform recording
David Renfro from Infiniti Integration Services describes SEL continuous waveform recording as the arbiter of truth and as a method for capturing all disturbances without custom event trigger logic. Learn how he optimizes filter designs for harmonics caused by variable-speed motor drives.
