Reactive power is that componenet of total power which is
required for magenetisation of Elctric equipments such as
Transformers, Motors, Generators etc. Alternatively we can
say that power utilised for magenetisation of electrical
equipment is reactive power. In power trianle it can be
explained as follows

*
* *
* *
Reactive * * Total power (S)
Power(Q) * *
* 0 *
* * * * * * * * * *
Active Power (R)

0 - power angle.
