SEL-734 Revenue Metering System
The SEL-734 Meter combines exceptional revenue metering with advanced power quality monitoring and
analysis. |
 |
| Accurate Metering | |
| Exceeds ANSI C12.20 0.2 Accuracy Class with 0.06 percent accuracy at unity power factor with bidirectional, full four-quadrant energy metering for generation, interchange,
transmission, distribution, or industrial applications. |
|
| Load Profile Data Collection | |
 Use the 12-channel load profile recorder to sample from 385 available values such as VARS, watts, power factor, and harmonics. |
|
| ACSELERATOR® QuickSet® SEL-5030 Software | |
| Save engineering time while retaining flexibility. Communicate with the SEL-734 through any ASCII terminal, or use the ACSELERATOR software graphical user interface. The optional Ethernet communications port offers simultaneous engineering, SCADA, and MV-90 access. |
|
| Power Quality Monitoring | |
 Improve customer service by recording the time and duration of voltage sags, swells, and interruptions. Take corrective actions on high harmonic distortion. |
|
| Secure Communications | |
Use the SEL-3021 Serial Encrypting Transceiver to secure meter communications. |
|
| 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 + 10ms. Measure instantaneous voltage and current angles in real time to improve system operation with synchrophasor information. Learn More > |
|
| 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 as shown below. The predictive demand alarm
is available through Modbus, DNP, MIRRORED BITS® communications, or the front-panel LEDs. |
