Capacitor Bank , Power factor Improvement , why use Capacitor Bank
Basic Power Factor Theory: Power Factor compares the active power (kilowatts or kW) with apparent power (KVA) that is demanded from the power source. It is also a comparison of the active current to the total current, as shown in the triangle below. It is also equal to the cosine of the angle of displacement between the voltage and current waveform. The ratio of actual power to apparent power is usually expressed in percentage and is called power factor. Generally the Transformers are inductive loads and cause very low power factor during their testing. Inductive equipment needs magnetizing power to produce the flux necessary for the operation of inductive devices. The unit of measure of magnetizing or reactive power is the kilovar (kVAR). The active power (kW) and reactive power (kVAR) together make up apparent power which is measured in kilovolt-amperes (kVA). By representing these components (kW and kVAR) of apparent power (kVA) as the sides of a right triangle, we can ...
