The rms value of an alternating current is defined as that value which, taken to direct current, produces the same caloric effects. It is a characteristic value, which on the other hand is the one provided by measuring instruments, whether analog or digital.

The electrical task is that aerial or underground connection that connects in the electrical installations the part of the distribution network of the supplying company with the protection box or boxes.

An electric generator is any device capable of maintaining a difference in electrical potential between two of its points, transforming mechanical energy into electrical energy. This transformation is achieved by the action of a magnetic field on the electric conductors arranged on an armature.

The system must be considered from the point where it is generated and this can be thermoelectric or hydroelectric, it is composed of the generator, the upstream transformers to the high voltage distribution network, the downstream transformers that feed us and the internal network of the house or building. In Mexico it is generally configured as follows: “127 / 220V, 3F, four wires, 60Hx.”, It can also be expressed as: “127-220V, 3e + N + TF, 60Hz.”, Where V corresponds to the voltage between phases and neutral and phases, “3F” correspond to the 3 phases of the system, “N” corresponds to the neutral generated in the transformer that feeds us and “TF” corresponds to the physical ground that we must provide to the system.

This term is also known as voltage and it is the amplitude that reveals the difference that exists in the electrical potential of two points. The unit of measurement for this voltage is called the volt. Another name that electric tension receives is potential difference and we can also define it as the work for each unit of charge exerted by an electric field on a charged particle, to move it from one determined position to another.

A power outage or blackout is the loss of electrical power supply in an area that can cause machine failures that can be harmful to equipment resulting in incalculable monetary losses.

Electromagnetic interference is the disturbance that occurs in any electronic circuit, component, or system caused by an external or internal source of electromagnetic radiation. This disturbance can disrupt, degrade, or limit the performance of a system. The source of the interference can be any object, whether man-made or natural, that has rapidly varying electrical currents, such as an electrical circuit.
