accidental touching of potentially live parts
Inspect the condition of the apparatus
Check for soiling, corrosion and moisture
Check for increased temperatures that have
occurred on the main circuits
Visual checks for traces of partial discharges on
the insulator parts

LV terminals for firm seating
Check the connector pins of the multiple plug

During operating voltage, no exterior discharges
may appear on the surfaces of the electrical
equipment. This can, for example, be determined
by characteristic sounds, a clearly perceptible
IMPORTANT!
Never put oil or grease in the guide of the

8.2.1. Cleaning
If during inspections, the need for cleaning
measures is determined, the procedure should be
be isolated according to the “Safety
Regulations” prescribed by DIN VDE/IEC and

Cleaning the surfaces of insulating parts and
conductive components
such as Rivolta BWR 210

8.2.2. Check the Pole Inside Gas Pressure
This check CAN be performed every 5 years
Indicator:
0.2 – 0.8bar (overpressure) at 20 °C = OK
If the pressure falls below the prescribed
value, the apparatus should be refilled in the
factory
defined and controlled dry atmosphere.
The initial factory pole filling is in the range of 0.5
to 0.8bar at approx. 20°C. To check this, a specific
part, must be used.
