This paper explores the method of reactive power compensation using shunt capacitors for two cases. The first case involves a load fairly close to the AC source. The shunt capacitors are injected into the circuit by a logic circuit which uses the reactive power absorbed by the load, which are inductive in nature, as its input. The second case …
