GLOSSARY
It is the maximum value that the wave takes and that we know as Amplitude, in principle, there would be two values: positive peak value and negative peak value. The peak value is related to the effective value as follows: Vpp= Veff x 1´4142
It is normally twice the peak value; is the maximum excursion that the amplitude of the signal can take. It can also be expressed as the difference between its positive peak or maximum and its negative peak. Vpp= Vp X2
The periodic waveform repeats continuously after a defined time interval.
The AC input cable of the AVR or the UPS, there are three integrated cables (line-neutral-ground)
Power factor is a measure of the efficiency or performance of our electrical system. The power factor is the relationship between the apparent power (VA) and the active power (W), always trying to ensure that the active power is as close as possible to the apparent power.
There are three conditions that determine the power factor according to the load connected to an electrical system.
1.- Resistive load, current and voltage in phase power factor equal to 1.
2.- Inductive load: this delays the current with respect to the voltage, therefore it decreases the power proportionally to the percentage of phase shift that it has.
3.- Capacitive load: it delays the voltage with respect to the current, therefore, it decreases the power proportionally to the percentage of phase shift that it has.
The displacement of current with the voltage produces waste of electrical energy and generates harmonics that are corrected by connecting proportional inductive or capacitive loads that compensate each other.
A power inverter is a device that changes or transforms a direct current input voltage to a symmetrical alternating current output voltage, with the magnitude and frequency desired by the user or the designer.
It is defined as the current that flows through one of the loads connected to a single-phase or multi-phase system
When capacitors or inductances are installed in an alternating current (AC) circuit, peaks in voltage and current do not occur at the same time. The fraction of the period difference between these peaks expressed is said to be the phase difference.
The physical earth is a cable or conductor grounded to a rod of 2 to 3 meters buried in the earth, it can be made of aluminum or copper so that it is sufficiently conductive. which becomes part of the electrical installation and serves to prevent electrical shocks and also to discharge the static electricity generated in the cabinets and components of electrical appliances.
A circuit used in switching regulated power supplies where the switching frecuency is held constant and the width of the power pulse is varied, controlling both lines and load charges with minimal dissipation possible.
