WebHitachi Energy’s series reactors are usually the magnetically shielded air core design, the electromagnetic coil is connected in series in the electric circuit. Series reactors may also … WebEach saturable reactor’s impedance is determined by the application of DC power to a control winding. As the level of power supplied to the control winding is increased, the saturable reactor becomes more saturated. This reduces the impedance of the AC gate winding, and increase the amount of the supply voltage that is transferred to the load.

WebHow to calculate power factor. To calculate power factor, you need a power quality analyzer or power analyzer that measures both working power (kW) and apparent power (kVA), and to calculate the ratio of kW/kVA. The power factor formula can be expressed in other ways: PF = (True power)/ (Apparent power) OR. PF = W/VA.

Web7. By reducing the impedance of the saturable reactor, the load impedance becomes a higher percentage of the total impedance and thus more of the input voltage is dropped (transferred) across the load. 8.
