      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 load centers.

      With optional continuous waveform streaming, the SEL-735 precisely samples and sends waveform data from the power system at 3 kilosamples per second (ksps). The SEL-735 displays this oscillography in real time on the optional 5-inch color touchscreen or via SEL Synchrowave software.

      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. Load profile history is available to view, retrieve, and analyze for years, thanks to the available 1 GB of onboard storage.

      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 SEL-5705 Synchrowave Reports software. This combination of hardware and software simplifies ordering and license management, eliminates large up-front base license fees, and allows utilities to incrementally purchase the software device license for that meter.

      Details

      Accurate Metering
      The SEL-735 exceeds the requirements of ANSI and IEC accuracy standards over a wide current range. Capable of reliable and precise metering even in the presence of harmonics, the SEL-735 exceeds the 0.1 accuracy class requirements of ANSI C12.20 and 0.1 S accuracy class for IEC 62053-22. Quality-focused manufacturing ensures that the meter will meet these accuracy requirements throughout its service life.

      Load Profile Data Collection
      You can collect billing data with a simple-to-use load profile recorder that captures years of data.

      Advanced Integration
      The SEL-735 integrates seamlessly into Itron MV-90 billing software, IEC 61850, DNP3, IEEE C37.118, Modbus, or SEL communications architectures. Multiple communications ports and protocols enable the SEL-735 to simultaneously communicate with up to ten devices.

      IEEE C37.118.1a-2014 Synchrophasors—Collect real-time measurements of electrical quantities, then use these data to perform wide-area control, validate system models, determine stability margins, maximize stable system loading, detect islanding, record system-wide disturbances, and visualize dynamic system responses. The synchrophasors in the SEL-735 adhere to IEEE C37.118.1a-2014, making them ideal for applications requiring fast response times under dynamic conditions.

      Instrument Transformer Compensation
      The SEL-735 is the only SEL product to provide both angular and magnitude compensation for instrument transformer errors. Correct delays and errors on each phase to achieve high-performance system accuracy, even when using protection-grade transformers. The SEL-735 is equipped with the powerful combination of IEEE C37.118 and Instrument Transformer Compensation (ITC), so you can choose to apply correction at either the synchrophasor interface or all metering interfaces, providing flexibility for many applications.

      IEC 61850 GOOSE and MMS
      Using IEC 61850 GOOSE, the SEL-735 can communicate peer to peer with another device to exchange metering, power quality, or control data in real time over Ethernet. Or, it can use MMS to report to an MMS client, such as a SCADA master.

      Transformer and Line-Loss Compensation
      By entering transformer nameplate and line impedance information directly into the meter, you can automatically compensate for transformer or line losses and move the billing point.

      Time-of-Use (TOU) Metering
      You can report flexible, time-differentiated energy and demand registers with multiple day types, rates, and seasons as well as a 20-year programmable calendar.

      Predictive Demand
      With the predictive demand function, you can monitor accumulated demand and alarm when the demand exceeds a user-defined limit. The SEL-735 can then shut down loads or peak-shave with generation to avoid demand charges. The predictive demand alarm is available through IEC 61850, Modbus, DNP3, Mirrored Bits communications, and the front-panel LEDs.
