Fault Recorder Panel

Fault Recorder Panel

In power plants or substations, a variety of events may occur, including the following: device operation or control for electrical power facilities and the operation of circuit breakers by protection devices in case of failure in power plants or substations.

Accurate analysis for those various events plays a crucial role not only in stable and reliable operation of the power system facilities but also in measures to prevent potential accidents in the future.

Fault recorder panel provides a function to record, store and analyze a wide range of power system data.
