- Accurate Metering
Exceeds ANSI C12.20 0.2 class accuracy at unity power factor with bidirectional, full four-quadrant energy metering for generation, interchange, transmission, distribution, or industrial applications.
- Load Profile Data Collection
Collect billing data with a simple-to-use load profile recorder that captures years of data.
- Synchronized Phasor Measurement
Combine the SEL-734 with an SEL IRIG-B time source to measure the system angle in real time with a timing accuracy of ±10 µs. Measure instantaneous voltage and current angles in real time to improve system operation with synchrophasor information.
- Transformer and Line-Loss Compensation
Enter transformer nameplate and line impedance information directly into the meter to automatically compensate for transformer or line losses and move the billing point.
- Time-of-Use (TOU) Metering
Provides flexible, time-differentiated energy and demand registers with multiple day types, rates, seasons, and a 20-year programmable calendar.
- Predictive Demand
The predictive demand function monitors accumulated demand and alarms when the demand exceeds a user-defined limit. The SEL-734 can then shut down loads or peak-shave with generation to avoid demand charges. The predictive demand alarm is available through Modbus, DNP3, Mirrored Bits communications, or the front-panel LEDs.
- Flexible Mounting Options
A variety of bezels, brackets, enclosures, and rack-mount kits are available for quick, easy, and clean-looking retrofit installations and mounting flexibility.
