SEL-735

Power Quality and Revenue Meter

The SEL-735 Power Quality and Revenue Meter is fully Class A-compliant to the IEC 61000-4-30 power quality standard. With reliable Class A measurement, operators can identify power system anomalies and isolate their source with confidence.

For high-accuracy revenue metering applications, the SEL-735 exceeds ANSI C12.20-2015 0.1 and IEC 62053-22:2003 0.1 S accuracy class requirements over a wide current range. This makes the SEL-735 the premiere choice for generation, interchange, transmission, distribution, or industrial applications.

The 5-inch, 800 × 480 color touchscreen available on the advanced meter displays high-resolution metering and power quality information without the need for a PC. With it, you can view metered quantities, phasor diagrams, voltage and current waveforms, and more.

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.

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.

With the powerful combination of instrumentation transformer compensation and IEEE C37.118 synchrophasors, you can choose to correct delays and errors on each phase to achieve greater system accuracy.

Automate Data Reading (Time-of-Use)—Capture rate-based demand and energy consumption, configured with a user-defined calendar. A user-defined schedule instructs the meter to perform a particular action at a specified time, such as a self-read or demand reset. You can apply time-of-use metering to bill consumption at different rates based on season, day type, and time of day.

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.

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. The SEL-735 can trend averages, minimums, maximums, changes, and snapshots at a rate as often as every three seconds.

Capture Waveforms and Trigger Records—Record up to 10,000 oscillography events associated with programmable trigger conditions, such as a voltage interruption. You can also capture real-time voltage and current signals in both the time and frequency domains with the Wave View oscillography functionality.

Voltage Sag, Swell, and Interruption Logging (VSSI)—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.

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 C12.20-2015.

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.

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.

Optional Touchscreen Display
With the advanced meter’s easy-to-use touchscreen interface, you can:

  • View a real-time phasor diagram to verify wiring.
  • Verify energy accuracy in Test Mode while confirming real-time power flow.
  • Read billing data, including energy consumption and peak demand.
  • Monitor voltage, current, power factor, frequency, and power.
  • Analyze system waveforms with built-in oscillography.
  • Configure settings with just a few touches.
  • Create complex passwords using the QWERTY keypad.
  • Commission the meter without a laptop.
