There was recently a fatal accident..In fact,one of our colleagues was working on the disconnecting switch in derivatin of 22 kv line feeding one client.The electrician had placed eartings before starting to work. This 22 kv line is in parallel with 60 kv line ( 20 m between the two parallel lines). The two lines were not under voltage when the electrician was working..
At the moment of powering the 60 kv line, the electrician had been electrocuted..

Please help us to explain these accident?

We are suspecting induced volatge in these accident..
We want to do some measurements to understand what happened ( to measure induced voltage or current)..What material can we used?

Thanks for help

It is unfortunate to hear of loss of life that resulted from working on or near electrical systems. Hopefully, others around him can learn specific procedures to reduce the liklihood that it does not happen to others doing similar work.

Lines and other conductive objects may acquire dangerous potential from
electrostatic [capacitive] and/or electromagnetic [Inductive] effects in proximity to lines or other gear, or may be affected by lightning or associated weather conditions related to storm activity.

Very specific, carefully studied forms of protective grounding can be applied to limit contact hazards, but nothing should be attempted without careful review and acceptance by your employer.

On the North American continent, there are mandatory rules such as those in OSHA 29 CFR 1910.269 that apply to electric-utility and non-utility workers that are in proximity to electrical transmission and distribution systems. There is no substitute for years of formal training and closely supervised experience that eventually make a person qualified to do work that elsewise can be very dangerous.

Due to the extreme hazards involved, you should in no way attempt to reproduce aspects of the accident nor conduct any sort of tests, but study and learn from others’ formal work and published data regarding the events that ended your associate’s life. The hazardous conditions that led to the accident may have been of a transient nature, and be very difficult to measure except under tightly controlled and well understood circumstances.

Appropriate action now may be to assist public occupational-safety officials that are responsible for investigating the incident.

Sorry for opening this up again, but I just can't help thinking that there is something wrong with this story.
Fatin, states that there is a 20m (metre?) seperation between the services, as in different Cross-arms.
Fatin, as a Practising Line Mechanic/Faultsman/Electrician, from NZ that uses 22, 33 and 66kV, sometimes on the same pole.
66kV is on a wooden pole at the top, depending on the area, 33 would be under that and if you were really unlucky, you would have the 400/230V MEN system below that.
But all spaced at 5 metre intervals vertically.
So that you can get an EWP somewhere near the thing, after Faults have happened.
