Steps to oversee the implementation of a Roads Lighting 2
|
Switching centers:
A) switching centers (air)
- Is checking the dimensions of the excavations and concrete rules for character columns (H).
- Review the implementation of the ground.
- Checking the installation of the converter is well on its base.
- Examination of the high voltage breakers and lightning arresters.
B) switching centers combined (terrestrial)
- Review the dimensions of excavations in accordance with the rules of concrete plans.
- Review the entry and exit holes cables.
- Checking the grounding system of the plant.
Electricity distribution boards:
- Review the dimensions of the concrete base of the distribution panels.
- Review the implementation of special ground panel.
- Examination of the ends of cables and test the quality of communication with the incisors.
The delivery of electricity:
- Instructions are issued to the contractor to connect to the electricity company to take actions necessary to deliver electricity at its current network connects with the high voltage transformers, and control the process of launching the electric current.
Electrical tests:
- Insulation resistance test cables are buried to the ground.
- Test the insulation resistance between the line and tie the three-phase and three phases on the exchange.
- A test to isolate the converter according to the test certificates converter.
- Test the intensity of dielectric transformers filled with oil and the level of the oil level according to the test certificates.
- Review the results of tests of resistance to ground.
- Measuring the intensity of lighting on the surface of the street in different places.
- Balance electrical loads on three phases in each panel distribution.
- Make sure the rate of voltage drop.
