Earthing of equipment
Earthing of equipment
(OP)
In electrical maintenance field there is a practise to measure Earth resistance of earth pit on periodic interval.
Is there any method to check/confirm the continuity of the earth conductor between earth pit (grid) to the equipments
Generally population of the electrical equipments are too large in industry,in that case what will be the pratical method.

of detecting faults in the ground system. Some one do it by means of parallel connected welding transformer in order to achieve 300-1000 A and a measuring accuracy.

Thanks for guidance but as you well aware the earthing grid acroos the plant (industry)passing thr several steel structure and if we adopt current injection method, practically it's not possible.
If any other way to test it, let us know.
Thanks

It is very easy to use, at least according to the web information.
I never used this and I could not recommend it.
