Test Equipment Description

Schloder VIS 740 Description:

With the Schloder combination voltage interruption simulator Schloder VIS 1700 Voltage Interruption Simulator and the step transformer VIS 740 voltage drop tests according the standard are possible – see chapter 5.1 of the standard.

The step transformer fulfilled the standard requirement regarding the high stability of the voltage. Other variable transformers or variacs are not useful usually. The switching of the voltages to 80%, 70%, 40% or 0% is performed by the position of the jumpers on the front panel.
