what is apparent power | , | What is real power | & | What is reactive power?

we are going to see what is apparent power, real power and reactive power.
And how it is produced.
Considered the power produced in power plant or power from some other source
It was connected with load
If the load is pure resistance there will not be any reactive power over the system.
So according to formula
S=P+jQ
At this time the power is fully concussed by load and also source is not get disturbed until it get over load
Let us considered other case
When the load has more inductance or capacitance over it then reactive power will come into picture

Discuss about generator relay testing, scheme and logic of ABB, SIEMENS and MICOM relay brother.

[@manojshukla3598]

Sir explain about fault current calculation and relay setting

[@abhishekra5990]

Sir, can explain about fault level calculation
