TT system is normally used for consumer power supply.No earthing system provided by power distributor.The owner must install the earthing protection by their own connection to the earth.They must installing a suitable electrode and safe arrangement for which they are responsibility to their installation.
Impedance earthing, also known as impedance grounding, is a method of grounding electrical systems that involves using a resistance or reactance to limit the fault current during a fault condition. This technique helps to maintain system stability and safety by reducing the potential voltage rise on exposed conductive parts and minimizing the risk of electric shock. It is commonly used in industrial and utility applications to improve the reliability of power systems and to protect equipment. By controlling the fault current, impedance earthing can also mitigate the effects of transient overvoltages.

In countries that are governed by electrical codes, electrical contractors abide by the rules set out in their areas code books. Within these publications there is information for the electricians that are doing the work. Conductor selections and calculations are used for proper sizing of wire. Pre calculated tables and rules tell the sizes and the method to install the equipment so that at the end of the project when the job gets its safety inspection, it will pass.

Wagner's earthing device, often referred to in the context of electrical engineering, is a system used to establish a reliable ground connection for electrical equipment. It ensures safety by preventing electrical shocks and reducing the risk of equipment damage from surges or faults. The device typically involves grounding electrodes and conductors that facilitate the dissipation of electrical currents into the earth. This grounding method is crucial for maintaining the stability and safety of electrical systems.
An earthing system can be defined as the electrical potential of the conductors relative to the EarthÍs conductive system. The choice of earthing method can influence the safety and electromagnetic compatibility of the power supply, and regulations can vary considerably among countries.
A slip ring is a method of making an electrical connection through a rotating assembly. Slip rings, are also called rotary electrical interfaces.,
