Guaranteed Revenue Accuracy
Exceed ANSI C12.20 0.2 class accuracy 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 Power Quality and Revenue Meter is three times as accurate as ANSI C12.20 accuracy class 0.2 requirements, over an extended operating range.

Advanced Data Logging
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 192 data channels for up to 5,000 days. 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. SEL-735 measures harmonics, interharmonics, flicker, power factor, voltage disturbances, K-factor, and other key power quality indicators. Record approximately 3,000 events associated 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.

Retrofit Installations Easily
Reduce wiring and connections by replacing socket meters with the SEL-735. Standard connector blocks make interconnections simple. Prewired solutions reduce shop and field time and provide a secure housing with plenty of room for accessories.

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, look at the Easily Extractable Meter (EXM) option from SEL.

Organize, Optimize, and Visualize Site-Wide Data
acSELerator Meter Reports retrieves site-wide data and displays it for analysis. Generate charts, reports, and manage data to drive planning, operations, and billing decisions.

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 C37.118-2011 Class P, 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. Alternatively, 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) access to plant information for generation control.

Automate Data Collection

Metering Solutions-Automate

acSELerator Meter Reports provides charts and reports to visualize the consumption of energy. With these data, operators can avoid peak demands and optimize a schedule that moves overlapping electric processes to off-peak hours. Automate data collection and improve efficiency by eliminating the need to collect data from field devices manually. 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 trip, or load dropout. Access critical information directly 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.
