Answer / gunnamsantosh

for transmission we use delta because we require 3 wires

Answer / v.venkata ramana

DELTA Connection

as for long transmission it is economical to transfer power
with 3 wire

Answer / atul gupta

it is delta.
because from one to another Lilo line is there. & another
to another s/s. it is just like a mesh.
every s/s jointed in grid mesh system. so we can say it is
delta connected..

Answer / krishna

delta

Answer / k.prakashchandra

At 400 KV stations 220/400 KV star connected auto
transformers are employed.There is no star or delta
connection applicable to trans line

Answer / gunnam santosh

mostly by using star because by using star we can reduce odd
harmonics

Answer / masoom raza

delta
as for long transmission it is economical to transfer power with 3 wire rather with 4 wire.

1- XC and the RC time constant are both measures of the reaction of C to a change in ____? 2-The power factor is a numerical ratio with a value between 0 and 1 equal to the ______________ of the phase angle. 3-When V and I are out of phase because of reactance, the product of V times I is called ______________ power 4-For _____________ inductors, the branch currents can be added algebraically. 5- The ______________ power in watts can be calculated as I^2R 6-Calculate XL with L = 30mH and f = 1kHz ( I have Xl=2piFL 2*3.141592653*1kHz*30mH =188 ohms Please check) 7-A parallel RL circuit has the values, R = 5kohms, XL = 5kohms. A voltage source of Vt = 10Vrms is connected in parallel to R and L. Determine the total current, It delivered by the voltage source Vt. 8-A series RC circuit has R = 1Mohm and C = 1microF. How long would it take for the capacitor to fully discharge if it is initially fully charged? 9-A circuit has real power = 300W and an apparent power of 500VA. Determine the power factor and phase angle. 10-The time constant for an LR series circuit is T = 0.1s and R = 10ohms. Calculate the inductance L.
