AMETEK introduces IEC61850 protocol on SERNET management system

AMETEK Power Instruments — a recognized leader in alarm management products — has added the IEC61850 protocol to its SERNET Alarm Management System. The new IEC61850 protocol has quickly gained acceptance for substation communications as a way to interconnect all intelligent electronic devices via a station bus, eliminating the need for discrete wiring and underperforming legacy protocols.

SERNET is an innovative Web browser-based alarm management system that records alarms with 1 millisecond precision for determining root cause and corrective actions. With IEC61850 protocol, the SERNET can receive alarms directly from other intelligent electronic devices using Generic Object Oriented Substation Events (GOOSE) messaging.

The alarm time stamp can come from the intelligent electronic device or via the SERNET, which is time synchronized with IRIG-B, NTP or IEEE1588 via GPS sources for 1millisecond sequence of events recording. These IEC61850 alarms can be re-transmitted using Modbus and DNP protocols for connection to legacy systems.

In addition to receiving alarms via IEC61850, the SERNET system can simultaneously receive digital alarm contacts that are time stamped and archived in the same database for one common Web browser-based display and analysis. The digital alarms can then be transmitted via IEC61850 for connection to other intelligent electronic devices.

IEC61850 also reduces installation time by eliminating the need for discrete wiring and by providing a standardized approach to system configuration using the open protocol.

AMETEK Power Instruments has long been recognized as a power and process industries leader with the industries’ most comprehensive line of alarm management and power measurement products, marketed under the Rochester Instruments and Panalarm brand names, and utility-hardened Pulsar communication products.

AMETEK Power Instruments is a unit of AMETEK, Inc., a leading global manufacturer of electronic instruments and electromechanical devices with annual sales of more than $3.0 billion.
