Testing the arrestor upper parts V50, V25, V20
and V10
The ISOLAB testing unit allows the checking the ar-
restor upper parts V50, V25, V20 and V10. The SPDs for the power supply usually have a
visual status display and can thus checked very
easily.
Besides arrestor testing, the ISOLAB also offers insu-
lation testing according VDE 0100-610.
