Power Quality and Revenue Meter
SEL-735
-
Schweitzer Engineering Laboratories, Inc.
The SEL-735 Power Quality and Revenue Meter passes accuracy requirements three times more stringent as the ANSI C12.20 Accuracy Class 0.2 standard. Advanced load profile trending, compatible with Itron® MV-90, DNP3, and Modbus protocols, ensures integration with practically any billing system. In addition to a full set of revenue metering features, advanced power quality monitoring will report costly system disturbances.

Product
Control Center
-
Schweitzer Engineering Laboratories, Inc.
The essential elements in the reliable operation of the bulk electric system (BES) are control centers that continuously monitor and control generation and transmission power flows. Visualization, situational awareness, and analytic software help ensure that control center personnel always know what is happening with the BES.
