DESCRIPTION
F61
Conversion rules for the voltage values of the disturbance record
* In order to obtain the phase voltages values at the VT primary, apply the following
formula :
« Read value » x « VT primary value » / « VT secondary value » x
coef
2
100
* In order to obtain the Vo value at the residual VT primary, apply the following formula :
« Read value » x « Residual VT primary value »/« Residual VT secondary value » x
coef
2
100
where : coef = 12600 for the range (57-130V) and 3400 for the range (220-480V)
