Reactor impedance kva
WebWe would like to show you a description here but the site won’t allow us. 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.

WebFeb 2, 2024 · Kilovolt-amps, abbreviated as kVA, is the typical unit of measure for what is called apparent power.Apparent power is the amount of electrical power produced by an electrical system at a particular applied voltage and current. Following the Ohm's law formula, we can obtain the amount of electrical power by multiplying the amount of … Webonly one of the four 25,000 kva. reactors connected. Since the impedance of a single switched reactor is four times that of the four reactors in parallel, the voltage rating of the shunt reactor would be: (4X.87) .13+ (4x.87) When ing voltage all four is: reactors are in service, the tertiary wind 0.87x13.8 kv. equals approximately 11.9 kv.
