Question { Siemens, 7110 }

What is meant by Active and reactive power?

Answer

Active Power:Which is convert from electrical energy.it is
measure by W,KW,MW
Reactive power:It happens in circuit at the time of current
flowing and induced magnetising.It is measured by Kvar.
Apparent Power:It is not converted,It is transforms
electrical energy.(Voltage depends cu loss,current depends
Iron loss)It is measured by VA.

These are Three types of power.

Question { AAPT, 4717 }

what is the Knee point Voltage?

Answer

Apply the voltage to secondary in ct,which point magnetising
current increases 50 % rise of voltage 10%.taht is called
knee point voltage.If you increase the voltage after the
Knee point u get the abnormal magetising current.
