CONTROL FUNCTION
Amplitude Selector
(Current) Sets the current amplitude. This value is set as a
percentage of the full scale current range. If the current
selector is set to 6000A output then 100% = 6000AAC
and 80% = 4800AAC.
Phase Angle Selector
(Voltage)
Sets the voltage phase angles. Phase A is used as the
reference.
Phase Angle Selector
(Current) Sets the current phase angles. The Phase A Voltage is
used as the reference.
Harmonics Switch Turns ON and OFF the voltage and / or current
harmonics.
Flicker Selector Sets the level and rate of voltage variation which causes
flicker in incandescent lighting.
Power Direction Switch Sets the power flow. The power flow can either be from
the source or the load.
Line Frequency Switch Sets the fundamental line frequency. The line frequency
can be at either 50Hz or 60Hz.
Power Switch Turns the MPQSIM ON and OFF.
Initial Settings
Connect the Power Quality Simulator to the Megger MPQ Analyzer as described in
Section 6.
