It is recommended that two points of the MV Station should be connected to the ground
system of the PV plant.
The MV Station needs to be grounded on site. The following operations should
also be conducted on site:
Measure the electrical conductivity between the device ground terminals and the
total equipotential connection copper bar to ensure the effectiveness of the
internal ground connection.
Perform the external grounding according to on-site situation and instructions of
the plant staff.
The grounding resistance should be no more than 4Ω.
The grounding resistance should be determined according to local standards
and regulations.
The country-specific regulations and standards must be observed at all times!
