Voltage unbalance
Select between disabled, predefined low, high and manually adjusted
unbalance on voltage.
Current unbalance
Selection between disabled, predefined low, high and manually
adjusted unbalance on current.
Frequency Selection between predefined system frequencies.
Event type
Select various network events: dip, swell, interrupt, inrush, signalling,
transient and adjust its parameters.
Event occurrence
Selection of event trigger (keys, time delay between selected events):
Keys only, 10 s, random, manual.
Sequence Redefine output voltage and current sequence.
Factory reset Resets system settings to factory defaults.
By using function keys, user can access scope and phase diagram screens or edit
menu, that allows modifying detailed parameters for each generated signal.
4.3.2 Fundamental voltage
By using left and right cursor keys user can select system fundamental
(nominal) voltage in 10 V steps within 50 V to 300 V range. Enter key
ENTER
allows user
to enter desired nominal voltage directly. Selected voltage is immediately applied on all
phases. If it’s necessary different voltage can be applied on different voltage outputs.
See section
4.9 Edit menu for details. If all other voltage options (harmonics, flicker,
events) are disabled then output voltage will be equal to fundamental voltage.
4.3.3 Fundamental current
Power Simulator current clamp output simulate A 1033 current clamps with voltage
output (ratio: 1 V = 1000 A). In order to get valuable results on the measurement
instrument, it is necessary to select A 1033 (1000 A/V) current clamps in configuration
menu. Please check measuring instrument Instruction manual for details.
By using left and right cursor user can select system fundamental (nominal)
current in 100 A steps within 100 A to 1000 A range. Enter key
ENTER
allows user to
enter desired nominal current directly. Selected current is immediately applied on all
phases. If it’s necessary different current can be applied on different current outputs.
See section
4.9 Edit menu for details. If all other current options (harmonics, inrush,
unbalance) are disabled them current output will be equal to fundamental current.
4.3.4 Network character
By using left and right cursor, user can switch between and set three network
characters:

Resistive network character
– where voltage and current are in phase

Inductive network character
– where current is lagging behind voltage
Phase shift can be adjusted, by entering the submenu
ENTER
and setting the
phase angle, by which the current lags the voltage. Current lag can be set
in 1°
