Lightning Disturbances on Distribution Lines
Lightning Disturbances on Distribution Lines
(OP)
Hie Guys
Good work, feels good to come onboard.
Please help. we are experiencing lots of disturbances on our 33kv and 6.6kv overhead distribution lines due to lightning. We have surge arrestors installed on strain poles and all the major equipment, transformers etc. It’s an open pit mining set up in Southern Africa and the rains have just begun. I was wondering whether there is something that can be done, protection wise, to reduce the number of trips. Also I have head somewhere about ZnO Surge arrestors please shed more light

Which of these measures do you want information on?

RE: Lightning Disturbances on Distribution Lines
Please shed more light on the triggered spark gaps, and duplex gaps. Also how much difference do arrestors on the line make and do we really need them like after every 10 poles looking from a cost point of view or should we limit them to sensitive equipment only?
