An electrical accident is an undesired, unexpected event that has been caused by an electrical current and has resulted in either injury or property damage. Electrical accidents are more common than you expect. In order to remain safe when using electrical equipment and appliances, it’s worthwhile to familiarise yourself with basic electrical safety knowledge. This will help to minimise the risk of incidents and prevent accidents. Main causes of electrical accidents In a world where we use electrical devices, appliances and equipment in almost all aspects of everyday life, electrical accidents are understandably common. Yet most can be prevented by understanding the dangers. Typically, electrical accidents are caused by contact with water, faulty wiring, attempting to fix electrical devices yourself, naked cords and damaged plugs. So, let’s take a closer look at each of these causes. Water is a conductor of electricity and can, therefore, be extremely dangerous when put into contact w...

Earthing or grounding It is the process of transferring the immediate discharge of electrical energy directly to the Earth with the help of the low-resistance wire. The electrical earthing is carried out by connecting the non-current-carrying part of the equipment or the neutral part of the supply system to the ground. A safety measure devised to prevent people from getting shocked if the insulation inside electrical devices fails is called Earthing. The third pin in the plug is actually the “Earth” or “Ground” connection of the electrical appliance. The Earth, being a good conductor of electricity, acts as a convenient path for the flow of electrons that escape the insulation. Furthermore, the gigantic size of the Earth paves a path for the safe discharge of the electric charge. Why is Earthing/Grounding necessary? There are 3 mains reasons why all electric devices need to be connected to the Earth. Human Safety -  A properly earthed device doesn’t leak out any current. This preve...

Reasons for using Stones in Electrical Switchyard & Transformer Yard: Stones in the substation is provided to reduce the step potential and touch potential when operators work on switch yard. Step and touch potential occurs due to the short circuit current flows on the conductor. All the substation is provided with the good grounding system or low resistance path to the fault current. Therefore to provide the high resistance for foot and ground, the stones are provided. Stones eliminate the growth of small weeds and plants inside the switchyard or transformer yard. It protects the moisture content evaporation and keeps the ground wet. Most in switchyard Power Transformers insulated with the insulation oil. The insulating oil spillages catches fire easily. So Stones/Gravel is provided to protect from fire when oil spillage takes place. Moisture on the floor level get minimised. Compensate the vibration in transformer which has been caused due to magnetostriction in core Improves yar...
