Protection monitor
The transient recorder is mostly used for monitoring protection operations. The VT & CT
waveforms and auxiliary protection contacts are recorded before, during, and after the fault
clearance. Expert System software can be used to analyze this data and report on any
abnormalities. Other information can be extracted for Power Quality and system
maintenance.
•
Disturbance recorder
Longer term events are monitored by the Disturbance recorder. RMS and phasor information
is stored twice per cycle per channel, and these are used to compute a variety of power
system quantities. A wide range of trigger options is available for the Disturbance recorder
including a flexible oscillatory power trigger.
This function is used for recording re-closer sequences and system stability events. It can
also be used to extend the pre- and post-fault times of a Transient record. A continuous
Disturbance logger can be added as an option that allows up to 2 weeks of recording time.
This records the RMS, phasor and frequency information at half the cycle rate. The
disturbance recorder is independent of the other recording modes.
•
Long term logger
The input and computed quantities are logged as maximum, minimum and average
quantities every minute. A 52-week log of data is saved by the system. This data can be
retrieved at reduced sampling rates for trending and power quality analysis.
•
Power Quality monitor
The parameters that define Power Quality are recorded by the TR-2100, and then processed
and viewed by applications running on a PC. These include:
Voltage & frequency profiles
Voltage dips & surges
Loss of supply
Harmonic content
Flicker
Imbalance
Flexible display options allow this information to be shown in a wide range of styles. Refer
to the Display Station manual for setup information.
