What is the Role of the Substation in Electrical Power System ? Substation Main Functions Why do We Need Electrical Power Substations ? The electrical power system is composed of generation, transmission, and distribution systems. The generating stations generate or produce electrical power. The transmission system transmits or send this produced electricity to overlong distances until it reach...

This video presents overview of Basic circuit elements; Resistor, Inductor and Capacitor, mainly the relationship between voltage, current and power. The pure resistor only consume active power. The active power is the multiplication of RMS voltage, current and cosine of angle between them. The reactive power is the multiplication of RMS voltage, current and sine of angle between them. As the a...

Why Cant Transformers and AC generators be rated in watts (W)or kilo watts (kW) or mega watts (MW). And why they should be rated in volt ampere (VA) or kilo volt ampere (kVA) or mega volt ampere (MVA) ? The main reason is, the capacity of the transformer is limited by two factors 1. the current that the transformer winding can carry and 2. the voltage it is designed to work without satuation. I...

Why Motor is rated in kW while transformer rated in kVA ? | why motor is rated in kw not in kVA ? Why Motor rated in kW/Horsepower instead of kVA? In case of motors, the customer is more interested on the amount of load it can drive to decide which motor is suitable to meet their purpose. Therefore, Electric motor rating is given in terms of shaft power. The shaft power is the measure of capaci...

Why current leads the voltage in a capacitor ? |Does current lead or lag voltage in a capacitor? The current in the pure capacitor leads the voltage by 90 degrees. You know the capacitor is nothing but two conductors separated by a dielectric medium. When a capacitor is connected across a voltage source, the voltage doesn’t build up instantaneously. The capacitor starts charging slowly by takin...

The current in the pure Inductor lags the voltage across it by 90 degrees. When a time varying voltage (for example, a sine wave) applied across a pure inductor , an opposing voltage called “back” emf is produced by the inductor due to its self-inductance. This back emf opposes and limits the current flowing in the inductor. Therefore, current through the inductor cannot follow the voltage acro...
