†Applicable to change or improvement.
‡Coefficients are derived with the following equations, and measurement values are
transferred by the multiplication of Data ID values (w.r.t secondary value) by the coefficients:
(1) Coefficients for currents (I L1 , I L2 , I L3 or I1, I2, I0):
where,
For example—in In=1A—we can have a coefficient: 1706.666667.
(2) Coefficients for voltages (V L1 , V L2 , V L3 or V1, V2, V0):
where,
For example—in Vn=110V—we can have a coefficient: 53.74606142.
(3) Coefficients for a frequency (f):
where,
For example—in fr=50Hz—we can have a coefficient: 68.26666667.
