encoding schemes: Scheme or multithreaded functional circuit diagram, single-core scheme.

Multimeter: an instrument with which we can measure various electrical quantities.

Absolute error: the difference between the value read in the instrument and the actual value.

Surge: an excess of tension is affecting ka grid. The surge can be generated by direct discharges of lightning, lightning remote downloads that are transmitted to the mains, switching network and the same defects.

Overload: occurs if the intensity exceeds the maximum allowable that can move through a conductor, causing overheating it. The overhead is given by an excess of used electrical appliances simultaneously.

Short-circuit: direct contact between drivers who are at different voltage, which causes the circle to line a very high intensity.

Surge: The excess of intensity. Can be caused by an overload, short-circuit, atmospheric discharge rate and the default isolation.

Fuses: some devices that are connected in series with the installation, so that the current circulates around them. Protect the installation against sobreintensitats. Inside there is a driver of low melting point or lower section of the line and therefore the time that exceeds the maximum intensity is open source and the circuit.

Type fuses (as shape and size): cylindrical, knife, screw. Type fuses (depending on the time of fusion): slow, fast and extraràpids.

Breaker (magnetothermic) is an element that protects the installation constr short-circuits and overloads. It consists of two main parts: 1) Magnetic: consists of a coil, a core and a mobile switch. In the coil being connected in series with the installation, is crossed by power consumption. If the flow is normal, the switch remains closed, but if exceeds preset limits, the nucleus is attracted and caused the opening of the switch. This part protects against short-circuits. 2) Heat: The bimetal metallic foil, if an overload occurs (albeit weak but persistent) are hot and arched, causing the opening of the circuit.
