Check of the Anti-Condensation
Heating
Check the proper function of the anti-condensation
heating within
the cubicle
(see figure 84).
3.3,'
Functi ona 1 Check o![ the Electri ca 1 Control
Circui ts
Perform one CL.05E- and one OPEN-operation.

Measurement of theJlP.erating
Times
Take the operating times on one CLOSE-
and one OPEN-operation
at
rated supply voltage.
The values have to correspond
to those given in the routine test-
cert ificate.
The opening time is the time from energizing the opening release to
contact separation.
The closing time is the time from energizing the closing release to
contact touch.

Check of the SF6
GIS
Quality
Check the gas qual il:ywith respect to the water content, SF6 content
and acidity. Use tre devices mentioned
in chapter 6.3, pos. 9, 11
and 18.
.
Nominal value (dew point):
Nominal value (SF6 content):
Nominal ·value (acidity):
-10°C
at nominal pressure.

~ 10 ppm
Measure at the hv-t:~rminals directly. The values have to correspond
to those given in the routine test-certificate.
