Special computer programs enable electricians much easier to plan where and how they will run the wire, where will be located branch and so on.
In this way, more and more electricians may remind us of specialists, because the design of electrical networks at the present time is done properly only through the computer.Special programs also allow control of parameters during operation of the installation.
Electric power is the product of two quantities: current and voltage.These two quantities can vary with respect to time (AC power) or can be kept at constant levels (DC power). Most refrigerators, air conditioners, pumps and industrial machinery use AC power whereas most computers and digital equipment use DC power (the digital devices you plug into the mains typically have an internal or external power adapter to convert from AC to DC power).
So in power systems where generation is distant from the load, it is desirable to step-up (increase) the voltage of power at the generation point and then step-down (decrease) the voltage near the load.
Secondly, it is often more economical to install turbines that produce higher voltages than would be used by most appliances, so the ability to easily transform voltages means this mismatch between voltages can be easily managed.14 Solid state devices, which are products of the semiconductor revolution, make it possible to transform DC power to different voltages, build brushless DC machines and convert between AC and DC power.Nevertheless devices utilising solid state technology are often more expensive than their traditional counterparts, so AC power remains in widespread use.Źródło: https://en.wikipedia.org/wiki/Electric_power_system#Basics_of_electric_power
Well, how can few people know the relevant programming device is often combined with its typical electrical functions.
Therefore, many specialists in the repair of electrical installations must also have knowledge of writing programs that respectively pokierowałyby machine operations.
Nowadays, more and more equipment is armed with complex electrical components, which must be assigned the appropriate settings, so that the whole system to function smoothly..
