      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.

      Improve Grid Operation

      Metering Solutions-improve

      Improve reliability and enhance the integration of variable resources into the bulk power system. Meters installed at renewable energy generation points can provide fast streams of accurate synchrophasor data to the system operator. The SEL-735 includes the latest version of the synchrophasor standard, IEEE C37.118.1a-2014, which makes it ideal for applications requiring fast response times under dynamic conditions.

      Communicate Intertie Data Securely

      Metering Solutions-communicate

      Share intertie data and limit privileges to read-only access using the SEL-3620 Ethernet Security Gateway. Alternately, you can choose the SEL Remote Intelligent Gateway (RIG) solution for read and control access. The SEL-3530 Real-Time Automation Controller (RTAC) allows the independent system operator (ISO) to access plant information for generation control.

      Automate Data Collection

      Metering Solutions-Automate

      Meter Reports software provides charts and reports to visualize the consumption of energy. With this information, operators can avoid peak demands and optimize a schedule that moves overlapping electric processes to off-peak hours. Automated data collection improves efficiency by eliminating the need to manually collect data from field devices. To streamline the process, acSELerator Team SEL-5045 Software identifies new reports, downloads them, and stores the information.

      Reduce System Downtime

      Metering Solutions-reduce

      The ITI (CBEMA) curves and detailed voltage event graphs can help both plant operators and power producers resolve issues before they affect consumers. The ITI curve classifies voltage events to indicate disturbance severities that cause malfunctions, such as insulation failure, overvoltage trips, or load dropout. Critical information is directly accessible at the control center with SCADA-ready SEL meters. Up to ten simultaneous communications sessions provide real-time data, enabling operators to respond quickly to disturbances, reclosing events, alarms, and device failures.
