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.
Main functions
- Provision of high precision measurement data using high sampling frequency (7680Hz)
- Provision of various activation conditions for saving fault waveforms and events
- Triggering by upper/lower limits, by rate of change (of voltage, current, frequency and power) or by specified digital inputs
Triggering by power swing detection; manual or automatic triggering
- 48 analog channels (12 voltage and 36 current channels) and 96 digital channels available
- Fault waveform recording in IEEE C37.111 COMTRADE format
- Automatic and manual transmission of event data
- Fault location
- IRIG-B time synchronization
- Synchro-phasor transmission in accordance with IEEE C37.118
- Self-monitoring on a regular basis
