Field Data Historian project builds upon communications infrastructure to produce cost-effective condition-based solutions

摘要

Over the past 10 to 15 years, utilities have seen tremendous growth in the number of smart relays and other smart substation devices. In addition, there have been significant advancements in communications to these field devices. The devices include microprocessor-based relays, meters, fault and event recorders, transformer dissolved gas analysis (DGA) monitors, battery monitors, bushing monitors, breaker monitors and transformer temperature monitors. While some of these devices provide traditional supervisory control and data acquisition (SCADA) data, they also offer data that can be used by various departments to improve the planning, operations and maintenance of power system assets.
