Non-conductive spaces

The protective measure protection through non-conductive rooms is used when working in the field of electrical energy technology in high voltage technology. The measure allows work to be carried out under voltage and is comparable to the method with insulating platforms, as used when working outdoors.

An electrical voltage is a potential difference between two electrically conductive bodies. Man usually moves on the earth's potential , which he sets equal to 0. A protective measure usually prevents man from touching a potential that deviates so much from that of the earth that it becomes dangerous for him. The isolated space prevents the person from reaching the earth potential and always raises the person to the potential that endangers him without giving him the opportunity to touch another potential. Without another potential, there is no dangerous voltage (potential difference). The rooms are isolated accordingly and the distances are set so large (min. 2.5 m) that you can only touch one potential at a time. This includes areas under floors and up to the ceiling.
