What protective equipment is used in electrical installations up to 1000 volts?
To make the information more accessible, we will immediately provide a list of electrical protective devices used in installations up to 1 kV and tell you why each device is used. So, the main set includes:
- Rubber dielectric gloves. Protect hands from electric shock. An important requirement - before use, be sure to check the tightness of the gloves.
- Insulating rods. They are used to install and remove fuses, as well as to mount portable ground in electrical installations (EU) and release the victim in case of electric shock.
- Voltage indicators. Used to determine if there is voltage on live parts or not.
- Hand tools with plastic coated handles. It is used directly for connecting and repairing electrical installations with voltage up to 380 Volts. About, what tool kit should an electrician have, we told in the corresponding article.
- Insulating ticks. With their help, tubular fuses are installed, as well as remove insulating linings, guard panels, etc.
- Electrical clamp meters allow you to measure current, voltage and resistance in a circuit. About, how to use current clamps, we told in the corresponding article.
We draw your attention to the fact that these devices are designed for use in indoor and outdoor installations if the weather is dry. To work in wet weather, it is necessary to use tools specially designed for this.
These are all the main electrical protective equipment used in electrical installations with voltage up to 1000 V. As you can see, the list of primary devices is small. Now consider what is included in the set of additional security features.
When working in electrical installations up to 1 kV, it is sufficient to use at least one additional protective device. The list includes the following items:
- Dielectric boots, galoshes and bots. The first two tools can only be used when working in electrical installations up to 1000 Volts, in bots it is allowed to work at any voltage.These electrical protective equipment is needed in order to isolate the worker from the base on which he stands.
- Dielectric rugs and paths. The purpose is similar to the previous version; it can be used in closed power supplies of any voltage.
- Insulating stands. Prevent direct human contact with the floor. At voltages less than 1 kV, the use of electrical protection stands without porcelain insulators is allowed.
- Insulating caps, covers and linings. They provide protection against electric shock and prevent short-circuiting. An example of use is shown in the picture:
- Booms for leveling and transferring potential. They are used accordingly in order to transfer the potential of the overhead line to the workplace of the electrician, as well as to equalize the potential between the individual shielding kit and large-sized devices for which the potential value is not constant.
- Dielectric stepladders and ladders. They protect a person from electric shock when working in electrical installations. Stairs are made of fiberglass, which isolates the worker from the base on which the staircase itself stands.
Finally, we recommend watching a useful video on the topic:
All of the listed electrical protective equipment in electrical installations up to 1000 V (both basic and additional), must be checked, as well as periodically conduct tests of dielectric properties. We will definitely tell about this in the following articles!
