Reactive power is the power consumed by highly inductive
loads like induction motors (windings are highly inductive)
and supplied by capacitors
(power factor correction). in some cases this power can be
supplied into a power system by means of condensor motors
which can be made to run at leading or lagging power factor
depending on thier excitation.
Active power is mainly consumed by pure resistive loads
like a bulb or an electric kettle.
In a pure inductive load, the power factor is lagging
because the current wave lags behind the voltage wave by 90
degree.
In a pure capacitive load, the power factor is leading
because the current wave leads the voltage wave by 90
degrees.
A pure resistive loads has no phase shift. The current and
the voltage waves reaches maximum and minimum values at the
same time.

Assuming that a dedicated neutral earthing transformer is provided for each GT generator, when the two generators are running in parallel, has consideration been given that the earth fault current from one generator stator winding be split between the two neutral earthing transformers? If so, what adverse impact will this have on the operation of the 59N and 27TN devices?
