Electrical Power Concepts
When electric power is transmitted over long distance, voltage level falls due to the losses in the power line. Hence it is desirable to control the voltage of transmission line. In order to obtain constant voltage at the consumer’s end, voltage drop must be compensated to obtain a desired value. For that purpose, booster transformer … Read more
Cosine of the phase angle difference between current and voltage waveforms in an AC circuit is known as power factor ↗. The value of power factor lies between 0 and 1. It is to be noted that generator and alternators doesn’t have their own power factor. It is the characteristics (nature) of load connected to … Read more
Power generated at the generating stations need to be transmitted over long distance. In order to reduce I2R losses↗, we have to reduce current. Hence voltage is stepped up during the transmission of power by using using step up transformers. Step up transformers used in the transmission network are known as power transformers. Distribution transformers … Read more
Transformer is a static magnetically coupled device. It works on the principle of faraday law of electromagnetic induction. In this article, we will only discuss the various parts of transformer. If you want to read about the working of transformer, kindly read the following article: How transformer Works ↗ Various parts of transformer is as … Read more
