10.2. Calculation of Loop Voltage
The three phases of the transmission line are well capable to induce fluxes in this loop.
The total flux, which is the vector sum of these three fluxes are responsible to generate
the loop voltage.
From Figure 47;
'
= 0
"
= 0.8442
I = 460 Amps
A
Substituting the above values in Equation (20), the flux induced by phase A is given by;
A
= 3.7626 e-005
Considering phase B;
'
= 0.

"
= 0.

I B
[ cos(
120°
) + * sin(
° ) ]
= 460 i 120
Substitution of the obtained values in Equation (22) results in achieving
B = 0
Considering phase C;
'
= 0.
8442
"
= 0
I C
[ cos(
120°
) + * sin(
° ) ]
= 460 i 120
From Equation (24);
C

Implementation of Equation (25) results in achieving the total flux induced in the
auxiliary mitigating loop. Therefore;
