Protective earthing (grounding) inside the MVS
The protective earth (PE) terminals or frames of all the main components in the MVS are
connected to two main PE busbars located inside the station.
At the installation site:
•
measure the continuity of all internal PE connections by measuring the conductivity
between each protective earth terminal and the main PE busbar.
•
earth the shields, armors and protective conductors of all incoming cables to the
appropriate earthing terminals of the station.
For more information, see drawing 3AES-PVS-175-MVS-02-DW02
Measuring the insulation resistance of the cabling
Make sure that the insulation resistance of the external power cables are measured according
to manufacturer recommendations and local regulations.
