JIGNESH PARMAR
SIR
PLEASE SHARE WITH ME THE DETAILS ABOUT GUARDING OF ELECTRICAL LINE (110 KV)
IF ANY ADOPTED ANYWARE !!!
very good
thanks
Good morning Mr.Parmar:
Could you please send me, the minimum clearance between a 138KV transmission line and a street lighting circuit (different structures), or some equation to calculate it, in order to attenuate the mutual coupling between them?
Thanks in advance
