Electrical energy is the energy newly derived from electric potential energy or kinetic energy. When loosely used to describe energy absorbed or delivered by an electrical circuit (for example, one provided by an electric power utility) "electrical energy" talks about energy which has been converted from electric potential energy. This energy is supplied by the combination of electric current and electric potential that is delivered by the circuit. At the point that this electric potential energy has been converted to another type of energy, it ceases to be electric potential energy. Thus, all electrical energy is potential energy before it is delivered to the end-use. Once converted from potential energy, electrical energy can always be called another type of energy (heat, light, motion, etc.).
Safety work with the flow
Basic safety rules during contact with electricity are well known. However, in the case of a work such as electrical work daily contact with dangerous voltages may cause the vigilance of the employee is asleep. When an employee falls into a rut during the execution of orders, its security is threatened, and much easier for the accident. First of all, it is important to adequately protect the body from exposure to electricity. In addition, when touching the cables should always be touching the outer side of the hand, where possible, of course, since the shock hand grips on a same line and this may lead to disaster. It is worth remembering these basic principles.
Electrician as controller
In areas such as electricity even the smallest mistake can lead to enormous complications and even tragedies involving people. Therefore, one of the most commonly taken by the electrical service is to check the stability of the electrical conductivity and the installation and control of the measuring equipment. This is important not only for electric lines, which can be a source of electricity for homes and other buildings, but also in the case, for example, typically industrial facilities such as factories. The larger the scale of the electrical installation, including control electrical services must be carried out more accurately, since any failure threatens serious consequences.
