Ip = 10 A
Ton = π
T = 2π
Iavg = Ip*√(Ton/T)
Iavg = 10*√(1/2)
= 7.07 A
The average ON state loss in MOSFET, P = Iavg²*R
P = 7.07²*0.15
P = 7.5 W

emf = dΨ/dt = change of flux linkage
emf = dф/dt
emf = d(B*Area)/dt
emf = B*d(area)/dt
emf = B*d(πr²)/dt
emf = Bπ*2r*dr/dt
emf = Bπ*2r*change of radius per unit time
emf = 0.1*π*2*2
emf = 4π
Where,
Pmp is maximum power in watt
Vmp maximum voltage at maximum power in volt
Imp is maximum current at maximum power in ampere
Voc open circuit voltage in volt
Isc is short circuit current in ampere
Fill Factor = Pmp/(Vosc*Isc) = (Vmp*Imp)/(Voc*Isc)
= (2.65*0.5)/(0.7*3)
= 0.63
For lagging power factor = (IR*cosφ + IXsinφ)/V_r
For leading power factor = (IR*cosφ - IXsinφ)/V_r
Zero voltage regulation occurs on leading power factor only.
The main function of an interposing CT is to balance the currents supplied to the relay where there would be an imbalance due to the ratios of the main CTs.
Interposing CTs are equipment with a ratio that can be selected by the user to achieve the balance required.
An interposing CT is installed between the secondary winding of the main CT and relay.
Permissible overload = Full load kVA*factor for permissible load
= 1000*1.24
= 1240 kVA
