> Vunbalance, Aunbalance are calculated like THD values
> Thermal currents are calculated with the following formula:
Ath=(data) * 2 * (CT
2
)
> The parameters with sign should be preconverted as follows:
if (data)>$7FFF, means that the value is negative, and should be converted •
in complement of 2: data new = 0 - data
for PF parameters, if (data) > $7FFF => INDUCTIVE PF => the formula is:
•
(data-7FFF)/32768
for PF parameters, if (data) <= $7FFF => CAPACITIVE PF => the formula
•
is: (7FFF-data)/32768
