What protective equipment should be equipped with electrical installations

Each electrical installation must be equipped with protective equipment, while the entire set must be attorney and accompanied by certificates of conformity. Moreover, the concept of "electrical installation" includes such objects as switchgears, transformer stations, substations, workshops of a power plant, etc. A set of protective equipment can be an inventory of mechanized repair stations (hereinafter referred to as RMS), mobile laboratories, field teams and, of course, centralized repair teams.

Kit Overview


So, the following products are included in the KSZ-1 protective equipment kit:

  1. An insulating or universal bar (SHO-1 or SHOU-1, respectively) in the amount of two pieces.
  2. Insulating pincers KVP-2 or KI-1000 in the amount of two pieces.
  3. Two low voltage indicators (UNNO-1M or UNNU-25-1000).
  4. One portable substation grounding ZPP-1/3 with a cross section of 16 mm.kv.
  5. One dielectric mat.
  6. Two pairs of dielectric gloves.
  7. Two pairs of dielectric bot.
  8. Some safety glasses.
  9. Electrical safety posters (set may consist of 7 or 13 pcs.)




The complete set of KSZ-2 kit includes the following protective equipment for electrical installations with voltage above 1000V:

  1. Two insulating or universal rods (SHO-15 / SHOU-15).
  2. One single-pole high voltage indicator (UVNSZ 6-10).
  3. Two multimeters with clamp meter function.
  4. One portable substation grounding ZPP-15-3 / 1 with a cross section of 25 mm.kv.
  5. Dielectric mat measuring 75 * 75 cm.
  6. Two pairs of dielectric gloves.
  7. Two pairs of dielectric bot.
  8. Some safety glasses.
  9. Electrical Safety Posters (7/13 pcs.)

As well as the previous kit, KC3-2 comes already tested and attorney. The photo shows all of the listed items:


What else is important to know

When purchasing a ready-made kit, you should know about the timing of the test of protective equipment. According to current standards, we have compiled a table in which we indicated the name of the protective equipment and the frequency of verification.

PPE Frequency of verification (1 time per)
Insulating rod 2 years
Insulating ticks 2 years
Current clamp 2 years
Voltage indicators (low and high) 1 year
Dielectric gloves 6 months
Dielectric galoshes 1 year
Dielectric bots 3 years
Insulating Hand Tools 1 year
Safety belt 6 months
Claws and Claws 1 year

It is equally important to know about the following nuances:

  1. Workers responsible for the electrical industry, as well as technical managers of the enterprise, can increase the set of protective equipment for electrical installations, focusing on working conditions. However, making the kit smaller is prohibited.
  2. If the switchgear equipment is located on different floors, the number of protective equipment should relate to the entire switchgear.The same rule applies if the equipment is in different rooms, separated by other rooms or doors.
  3. Complete transformer substations, outdoor complete switchgears, and mast substations should be equipped with PPE based on local conditions.
  4. If the distribution devices in an amount of no more than four are located in the same building and at the same time they are of the same voltage and are serviced by the same personnel, it is enough to equip them with one set of protective equipment. However, this rule does not apply to portable grounding and protective fences, they must be equipped for each switchgear separately.

This is where we end the review of KSZ-1 and KSZ-2. We hope that now you know what means of protection are used to complete electrical installations with voltages up to 1000 V and above this value. Once again we repeat - it is more convenient to purchase ready-made kits, especially if they have already been tested and verified!
