IEC 61850 Now Available for SEL Power Quality and Revenue Meter

IEC 61850 Now Available for SEL Power Quality and Revenue Meter

Schweitzer Engineering Laboratories, Inc. has added IEC functionality as well as several other new features to the SEL-735 Power Quality and Revenue Meter. IEC 61850 is an international standard for communication and integration that supports systems built from multivendor intelligent electronic devices (IEDs) networked to perform protection, monitoring, automation, metering, and control.

The new IEC 61850 features include:

  • Up to 6 manufacturing message specification (MMS) client sessions for logging and reporting data
  • The ability to publish and subscribe to Generic Object-Oriented Substation Event (GOOSE) messages for applications requiring fast peer-to-peer transfer of metering, power quality, or event data
  • Support for device configuration using Substation Configuration Language (SCL) and Configured IED Description (CID) files for easy device setup

The SEL-735 also now includes support for instrument transformer compensation (ITC), which increases metering accuracy. Other enhancements include the addition of compensated and uncompensated registers to the transformer line-loss compensation (TLLC) feature, which simplifies site verification.

The SEL-735 provides metering accuracy, exceeding IEC and ANSI accuracy class 0.2 requirements, which ensures precise revenue metering measurements. The SEL-735 Meter is also IEC 61000-4-30 power quality compliant, providing accurate measurements—even in the presence of harmonics, out to the 63rd harmonic—to deliver a comprehensive power quality solution. SEL advanced metering systems meet or exceed the strictest ANSI, UL, and IEC requirements of utilities and industrial companies worldwide, offer a broad set of communications interfaces and protocols, operate from –40° to +85° C, and come with a ten-year, worldwide warranty.
