Hello,
I am reviewing design of our facility. We have 6.6 KV power generators and transformers which step down the voltage to 415 V.
Can any one guide me whether there should be separate Earthing grids for LV and MV equipments or we can use the same? One thing which i read somewhere is that: if we separate the networks, a constant circulation current would be observed as the reference point for the equipments would be different.
