6.1.3 EUT - Power and EUT - Control
For running the interruption, voltage variation and DIPS, the EUT Power 1 Input on the rear side of the
TRA3000 F-S-D-V-C must be connected to the mains. The mains is correctly connected if the green LED in
the symbolic power plug on the front panel of the TRA3000 F-S-D-V-C is glowing. The green indication will
only be visible when the phase and the neutral are connected in the right sequence. If the power main is
connected and the green light is not on, the mains cable phase and neutral must be interchanged. This
ensures that L and N as written on the front panel correspond with the phase and neutral of the mains.
Input power N> 50V and L-N <N Generator malfunction
No synchronisation signal
Message when N and L are
interchanged. Please change L
and N
Message when no PWR1 is
connected and SURGE test is
selected
Different parameter of the EUT power can be selected:
Press "Main" - and once "Menu" - "POWER"
display when "Main" has been
pressed
display after pressing once Menu
and "Power."
Power Main The angle turning "on" the EUT power synchronised to the EUT power
input of the TRA3000 F-S-D-V-C in degrees. With this feature inrush
current of EUT can be checked. The measurement of the current can be
made via EUT-Power I-CRO on the front plate on an oscilloscope.
Power No: This setting must be selected when d.c is applied to the PWR input.
Power PS3: With this setting the PS3 power can be controlled from TRA3000.
The PS3 allows to supply the EUT via the TRA3000 with different power
voltage and frequecies.
display when "PS3" has been
selected
With voltage the power and
Frequency of the PS3 can be
selected.
Display when power2 “Edit” has
been pressed
Variac voltage: When the variac with button PWR2 is activated the output voltage can
be changed directly by editing the output voltage. Online the power
voltage is measured and indicated on top of the display.
Current Lim.: When the EUT supply current will reach the selected limit the test will be
stopped and the EUT power will be turned OFF. The current limiter can
be used for automated test during night etc. The reaction time of the
limiter is several 100 ms. During a variac regulation, or while printing a
report the current limiter is inactive.
