Operation Manual

MI 2092 Power Harmonics Analyser Section III Operation manual
23
In Auto mode, START and STOP occur at user preset dates and times.
Recording can be stopped manually at any time.
Use SELECT key to toggle between MANUAL and AUTO mode.
In AUTO start/stop, use LEFT or RIGHT keys to select between Date and Time
and the UP & DOWN keys to set a new date or time.
Only valid date/time values will be accepted.
STAT. and PER.
STAT. Statistical Analysis
PER. Periodic Analysis
Use the SELECT key to enable (ON) or disable (OFF) the selected function.
ANOM.WINDOW
Recording of Voltage Anomalies
Use the SELECT key to toggle between Disable (OFF), FIXED Window or
VARIABLE Window recording.
In FIXED window mode, the window (and the Upper & Lower Limits) is set around
the nominal voltage and remains fixed during recording session.
In VARIABLE window mode, the window (and the Upper & Lower Limits) is set
around an average voltage dynamically calculated. Use the LEFT and
RIGHT keys to adjust the averaging period for calculating new values of
average voltage
(1 to 900 sec).
Voltage Anomaly recording is only available for those voltages selected for
recording (see 3.2.4 SIGNALS) even if Periodic Analysis is disabled. If
no voltage is selected, there will be no logging of Voltage Anomalies.
MAIN INTEGR.PER.
Integration (time) period for Periodic Analysis.
Use the LEFT and RIGHT keys to set the integration period
(between 1 second and 30 minutes).
POWER SUB.I.P.
Averaging sub period for power measurement. (Power sub IP)
Used in Periodic Analysis to average readings (see PERIODIC ANALYSIS and the
accompanying figure). Settable between
1 and 20 mains cycles.
Use the LEFT and RIGHT keys to set the required value.
NOMINAL VOLTAGE
The nominal voltage used as a reference in Voltage Anomaly recording.
In FIXED window mode, this is the actual voltage used.
In VARIABLE window mode, this is the start value of voltage, later modified to the
average value of voltage during the previous Integration Period while recording.
Use the LEFT and RIGHT keys to set the required nominal voltage (from 58.0 V to
450.0 V).
