CP CU1
The
CP GB1
grounding box is a surge arrestor unit for connecting the
CP CU1
to the test object.
If high voltage appears for a short time on the test object’s terminals, an arc discharges the
voltage and extinguishes without destroying the grounding box. If the arc persists for a longer
time period, the surge arrestor insulator melts and the terminals are short-circuited to ground,
thereby protecting the operating staff,
CP CU1
and
CPC 100
.
To short the phases, connect the line studs of the
CP GB1
as shown below.
