Three equal star-connected inductors take 8 kW at 0.8 power factor when connected to a 460 V three - phase 3-wire supply. If one of the inductor in phase – Y is short circuited, then the line current in phase-Y is ___ Assume RYB sequence.

Here, Y phase is shorted,
Equation of 3-phase power = √3*VL*IL*cosφ
IL = P/(√3*VL*cosφ)
= 8000/(√3*400*0.8)
= 12.55 A
Phase impedance = Vp/Ip
= 460/(√3*12.55)
= 21.16 ohm
cosφ = 0.8, So φ = 37 degree.
Here Impedance of Y phase is shorted,
So, Neutral point and Y phase at same potential,
Three line voltages are given by,
Vry = 460∟0°
Vyb = 460∟120°
Vbr = 460∟-120°
Here N and Y phase at same potential,
Ir = (460∟-120°)/(21.16∟37°)
= -21.7∟83° A
Ib = (-460∟120°)/(21.16∟37°)
= 21.7∟-157° A
Ib = -(Ir + Iy)
= -21.7∟83° + 21.7∟-157°
= 37.6∟53° A

In 2019, India stands ___ position in the consumption of electricity in the world.

As per the key statistics data of IEA With electricity consumption reached to 1,164 TWh in the country till November 2019, India ranked third among the top ten electricity consuming countries across the globe.

Case 1: The PV connected to the DC bus was injecting 20 kW of power constituting of 1 kW of loss
Case 2: The same PV is connected to the AC bus constituting to 1.5 kW loss. Find out the change in efficiency from Case 1 to Case 2?

In DC microgrid system,
Efficiency α 1/Pin
For 1 kW loss injecting power is 20 kW
For 1.5 kW loss injecting power will be proportional to 30 kW
So,
Efficiency will be reduced 0.025

At what range of wind speed is the electricity from the wind turbine is generated?

For small turbine starts generating power 12.6 kph (3.5 m/s) is the typical cut-in speed.
At 36–54 kph (10–15 m/s) produces maximum generation power.
At 90 kph (25 m/s) maximum, the turbine is stopped or braked.
