Disturbance Monitoring Equipment

Devices capable of monitoring and recording system data pertaining to a Disturbance. Such devices include the following categories of recorders: Sequence of event recorders which record equipment response to the event., Fault recorders, which record actual waveform data replicating the system primary voltages and currents. This may include protective relays., Dynamic Disturbance Recorders (DDRs), which record incidents that portray power system behavior during dynamic events such as low-frequency (0.1 Hz - 3 Hz) oscillations and abnormal frequency or voltage excursions. Phasor Measurement Units and any other equipment that meets the functional requirements of DMEs may qualify as DMEs.[1]
