Fault Recording Function
Triggered Slow Scan Function
Continuous Slow Scan Function
DFR Fault Recording
High speed recording, monitoring the transient response of the
power system and equipment during and just after a system fault
or transient disturbance.
TSS Triggered Slow Scan
Slow speed recording monitoring specified calculated power
quantities for up to 30 minutes before, during and after a
transient fault or disturbance at scan rates up to once per cycle.
Calculated quantities available include rms voltage and current,
real and reactive power, sequence components and frequency.
CSS Continuous Slow Scan
A slow scan function providing recorded calculated quantities
for up to 15 days for long term power stability monitoring. This
function requires a Local Storage Unit (LSU), an industrial PC
based storage device with a hard disk drive providing the long
term data storage facility. Quantities available for recording are
the same as those available for TSS recording.
Harmonics Recording
The power quality recording function in the IDM provides a
comprehensive harmonic recording function in compliance with
IEC 61000-4-7 class B. Harmonics can be recorded on two three
phase groups of analog channels - two groups of voltage
channels or one group of voltage channels and one group of
current channels. Up to 40 user selectable harmonic quantities
can be selected for each three-phase group of analog channels to
be recorded at a sample interval of one minute or 10 minutes.
Data is stored in substation memory as a contiguous block of
data and blocks of data of up to 365 days in size can be
retrieved for display and analysis using Replay
™
Plus Master
Station software.
