(9) Is lightning protection necessary?
You should ground your wind turbine. Proper grounding (illustrated
below) provides protection to individuals and equipment by eliminating
the possibility of dangerous voltage. Remember a steel tower is a
conduit for lightning. Every wind turbine and turbine tower needs to be
grounded at the tower base even though the system may be grounded
at the battery bank. Grounding the tower at its base may help prevent
shocks to persons touching the tower due to lightning or electrical faults.
Please take the time to review the National Electrical Code (NEC) and
local building and zoning regulations for complete requirements. Even in
“Off Grid Systems” there are multiple ways for tower grounding, the most
common method is a copper clad steel electrode(s) driven into the soil.
