SEL SEL-735 Power Quality and Revenue Meter
SEL-735
Power Quality and Revenue Meter
The SEL-735 offers high-accuracy metering combined with detailed power quality analysis. With data available at their fingertips, operators can easily identify power system anomalies and mitigate their impact.
For high-accuracy revenue metering applications, the SEL-735 exceeds ANSI C12.20 0.1 and IEC 62053-22 0.1 S accuracy class requirements over a wide current range.
The SEL-735 maintains this accuracy through its entire service life, eliminating costs associated with field calibration.
This makes the SEL-735 the premier choice for points of common coupling, interchanges, and critical loads.With optional continuous waveform streaming,
the SEL-735 precisely samples and sends waveform data from the power system at 3 kilosamples per second (ksps).
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 Accuracy Class 0.1 requirements of ANSI C12.20 and 0.1 S accuracy class for IEC 62053-22.
Quality-focused manufacturing ensures that the meter will meet these accuracy requirements throughout its service life.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.IEEE C37.118.1a-2014 Synchrophasors
