Introduction
德國SCHLODER 突發發生器
The clearly adjustable simulator VIS 1700 can simulate the voltage dips and voltage variations that can be
found on supply nets (AC and DC). Different modes of operation are possible:
Short interruptions : The supply network of the EUT can be interrupted in any phase position for
a defined time (0,1 ms – 9980 ms).
Voltage dips: The switching between the rated voltage U1 and the variable voltage U2 (U2
always <= U1) is always erratic. It can be set at each phase angle of the mains
begin or end. The standard test is defined at 40%, 70% and 80%. This test requires
the injection of the same phase voltage U2 at the rear of the device. A
step transformer (VIS 740) fulfilled the standard requirement. Fig. 1
Voltage fluctuation: Fluctuation to an adjustable voltage (0 95 % of U1). The parameters for release
time (0,1 – 70 sec.), test time (0,01 – 70 sec.) and recovery time (0,1 –
70 sec.) can be set individually. This is not an additional supply voltage required.
Fig. 2
Inrush current: For each EUT up to max. 16 A rated current (AC) can be measured the inrush
current on any phase position (0 – 360°).
For oscilloscope analysis there are three BNC jacks on the back side of the unit to examine the parameters
voltage, current and trigger.
