In an installation there is a three-phase load of 300 kVA with a power factor of 0.8 behind, in parallel with a three-phase load of 150 kVA with a power factor of 0.6 ahead. A pure reactive element is connected in parallel, and a unity power factor is obtained at the power input. Indicate the reactant of the element, with a positive sign if it is a bank of reactors, or with a negative sign if it is a bank of capacitors. Just put the corresponding sign followed by the numerical value, without units. The numerical value must correspond to the three-phase kVARS. You can use integer values with no decimal places or up to two decimal places
