{142 + [(Harmonic no-2) x 2] + 60 x
Constant Parameter }
For Example,
To find the 14 Harmonic address of
th
Voltage V31 following formula can be used:
Formula with the parameter :
{142 + [(Harmonic no-2) x 2] + 60 x C P}
Eg. {142 + [(14-2) x 2 ] + 60 x 5} = 466
So, Check the 14 Harmonic of Voltage V31
at 466 address.
