The purpose of grounding is to prevent step and touch voltages that will occur in case of a fault to be at a level that would endanger human life, or to completely eliminate these dangerous voltages.
There are several types of grounding. The main ones are; protection grounding, operating grounding and lightning grounding. Protection grounding: The inactive parts of the operating vehicles are connected to a grounding system that is properly installed in the ground, and protection grounding is obtained. What is important here is the grounding of a conductive part that is not in the operating circuit to protect people against dangerous touch voltages.
Operational grounding: It is the grounding of the operation current circuit for the normal operation of the facility. It is done by grounding the zero points of transformers in low voltage networks, a pole or middle conductor in direct current installations. Thus, the system tries to ensure that the voltage that will occur against the ground does not exceed certain values. Grounding of lightning protection facility: the grounding systems of these facilities must be independent from other grounding systems. The grounding system to be installed should be designed in accordance with the high current and magnetic field characteristics that will occur during lightning discharge. Thus, both other earthing systems in the environment and equipment and people should be protected.
Apart from these, grounding measures must be taken against static electricity charges. In this very critical issue, the necessary calculations and discoveries should be made in accordance with the grounding regulations in electrical facilities and the occupational health and safety law numbered 6331, and a special grounding system design should be made for each facility.
All works are carried out with the approval of an electrical engineer with SMM certificate and the relevant technical documents and proposals are submitted to you as approved.
