1.How electronic regulator differs from ordinary rheostat regulator Loss of power is very less while comparing the electronic regulator with an ordinary regulator and the reason for that is electronic regulator speed can be controlled so the needed power is used. In…
What is the generation and transmission of electricity The generation of electrical power is done with the help of natural energy such as wind, water, etc. This natural energy is then converted into electrical energy. In power stations the generation of electricity…
What is a Transformer Transformers are used in a power system that is capable to step up the power generated at low voltages to extra high voltages for transmission over long distances and then it could be transformed at low voltages In…
Transformers are one of the costliest equipment used in distribution and transmission process of power. The transformer has to go through different testing procedures periodically to prove that the transformer works properly. Deterioration of the transformer insulation resistance is one of the most common…
What is the transformer A transformer is a device that can transfer electrical energy from one circuit to another through an inductively coupled conductor which is the transformer’s coils. A varying magnetic flux will be created in the transformer’s core by the…
What is a filter used for and what does it do Electric utilities are always concerned about the power factor or power quality. Power quality problems may arise due to the variation in voltage, current or frequency and this may lead to…
What is wind and why wind power The wind is the movement of air masses around the earth, and this movement of air masses is influenced by two factors they are solar heating of the earth and earth rotation. Due to the…
The “earth resistivity” is a fundamental parameter that influences an electrode system’s earth resistance expressed ohm-centimetre. But it is not appropriate to calculate the actual value of surface resistivity to test the resistance of the electrode earth. Earth resistivity: Measurements of earth…
What is an electrical diagram Electrical diagrams are drawings which are used to represent electrical circuits, these circuits are represented by using lines, symbols, and number combinations. Electrical diagrams show the wiring between components and the relative position of the components. With…
What is memristor Memristor is a two-terminal device that can remember its history, and its resistance is depended upon the magnitude and polarity of the voltage applied to it and the length of the time that the voltage has been applied. So…
