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

Three-Phase Transformers
Three-segment transformers are a type of transformer used to transform voltages of electrical systems into three ranges. Two type transformers are shell-type transformer and core type transformer. In brief, it could be described because of the exquisite kinds of configurations.
Transformer
Ever since electricity has been created, people have started using it in its entirety. We see many types of Transformers in the neighborhoods. Some are smaller in size and some are very large. They are used according to their requirements. Many of us have seen the electrical transformer but they do not know what work they are engaged in.
Question
![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
