Earthing for generators
The electrical networks installed in our facilities is of the francophone type. The neutral and earths are not connected anywhere. Most of our installations are supplied with generator power (3 phase 5Kva - 25Kva). There are earths installed (now) in all our facilities.
Should we connect the neutral and earths at the distribution board or at the generator supply?
Do we measure the earth resistance at all earths separately?
What would constitute a satisfactory reading?
Is bonding of pipework recommended?
Should we install separate lightning earths and if so what would constitute a satisfactory measurement of earth resistance for such an earth?
