The entire complex of electrical installation works is divided into four stages.
For cables with voltage of 0.4 kV experience padded and shifted the cables before switching on and after maintenance. Test cables for voltage up to 1 kV for the balance sheet not regulated. Therefore, tests are carried out in accordance with the EMP and pteep once in 1-2 years.
For cables with voltage of 6-10kV:
Line up to 60 m in length, which is the conclusions from transformer substations to overhead lines, may not to experience.
