Energy meter: Meter provides wide-area visualization with synchrophasors

Energy meter Schweitzer Engineering Laboratories SEL

Utility testing: Schweitzer Engineering Laboratories Inc. (SEL) recently added synchrophasors to its SEL-735 Power Quality and Revenue Meter. With synchrophasors, users can now collect real-time measurements of electrical quantities from every SEL-735 Meter across their system. They can use synchrophasor data to perform wide-area control, validate system models, determine stability margins, maximize stable system loading, detect islanding, record system-wide disturbances and visualize dynamic system responses.

The SEL-735 supports the latest version of the synchrophasor standard, IEEE C37.118-2011 (as amended by IEEE C37.118.1a-2014) Class P, which makes it ideal for applications requiring fast response times under dynamic conditions. When used as a phasor measurement unit (PMU), this SEL meter provides synchrophasor data for frequency, phase, positive sequence components, four user-defined analog quantities and 14 digital status bits.

“The SEL-735 is designed as an economical yet high-performance meter,” said SEL R&D Manager Travis Mooney. “It passes accuracy requirements three times as stringent as the ANSI C12.20 Accuracy Class 0.2 standard. And, with three levels of power quality monitoring, it¹s easy to tailor the SEL-735 to virtually any application or budget.”

The SEL-735 features full IEC 61000-4-30 power quality compliance along with industry-leading accuracy, ease-of-use, reliability and price. In addition, the combination of instrumentation transformer compensation and IEEE C37.118 is unique to SEL and the SEL-735 Meter. Customers can choose to correct delays and errors on each phase to achieve high system accuracy, even when using protection-grade transformers.

SEL serves the power industry worldwide through the design, manufacture, supply and support of products and services for power system protection, monitoring, control, automation, communications and metering. For more than 30 years, SEL has provided industry-leading performance in products and services, local technical support, a 10-year worldwide warranty and a commitment to making electric power safer, more reliable and more economical.
