What is the grounding system?
The grounding system, a commonly called earthing system, is used in the electrical connection to set the ground connection. This connection serves as a safety measure to drain the flow of electricity in case of short -circuit or overvoltage. This is achieved by providing a direct connection with the Earth. The grounding systems are designed in two varieties: a protective country and a functional country. This system provides a ground conductor between all electrically conductive surfaces and the earth or ground conductor of the circuit. In this way, the electrical potential of these surfaces is adapted to the Earth's potential. It is almost impossible to be an electrical current in the layman because the unusual flow of electricity activates the circuit protection device. This is called a protective country.
Another type of earthing system system system. This system is designed to protect electrical wiring and components from damage caused by a sudden increase in power. A common example used to describe the function of this design of this grounding system is BLESK. The functional country works in the same way as the lightning rod, while direct surge Power and safely towards the ground. Functional countries are commonly used in overvoltage protection devices. These devices are used to protect electrical devices such as computers and TVs, from flash and overvoltage.
The low resistance of the protective ground is designed to create a short explosion of high current to activate the circuit protection device and switch off the power to the circuit. However, a functional country may allow the circuit to continue operation. Due to the high resistance of the functional country, the perimeter protection device may not be reached. To avoid this problem, a residual current detector is installed to reduce the flow of leaking to the ground. When the electric current leak is detected, the device closes the perimeter down.
In most modern buildings, the grounding system is incorporated into the power lines by one -onethe country's return of the country. The single -water return of the Earth is simply a metal electrode that is powered by the ground. It is connected to the main earthing wire in the electric service meter. This single -supply country return can provide a basic form of protection of the grounding system and electrical safety for the entire building. When it is correctly assembled, a single -water country returns as a protective country and a functional country for the entire electrical system.
