What protective equipment is used in electrical installations with voltages over 1000 V?

When working with high-voltage equipment and installations, it is imperative to protect against electric shock, especially if the voltage at the facility exceeds 1 kV. For protection, basic means are used that can be used under load, and additional ones, whose main purpose is to protect against touching dangerous live parts, as well as from exposure. Now we will talk about the main and additional electrical protective equipment used in electrical installations above 1000 V. Information is provided on the basis of the regulatory document RD 34.03.603.

The main

The set of the most important protective devices includes:

As you can see, the list of electrical protective devices is small, but all of them must be unconditionally present when personnel work in electrical installations above 1000 V.

Additional

Additional devices and means of protection include:

1. ... Protect workers' hands from electric shock. We draw your attention to the fact that in the list, gloves belong to the main set of protective devices, and not an additional one (according to the same RD 34.03.603).
   
2. Dielectric bots. They are used in order to completely protect the electrician from the base underneath.
   
3. Rubber mat. Like bots, it isolates workers from the base.
   
4. Insulating stand. When operating under voltages above 1000 V, it must be equipped with porcelain insulators.
5. Insulating pads and caps. They prevent the occurrence of a short circuit and are also an electrical protective device.
   
6. Extension ladders and stepladders made of fiberglass.
   
7. Potential leveling and transfer rods. They are used to transfer the dangerous potential of the overhead line to the place where the electrician works.
