DTSU666 series and DSSU666 series
three phase electronic energy meter
When the current is directly connected to the line, Ct shall
be set as 1.
Voltage ratio, used for setting the voltage ratio of the input
loop;
When the voltage is connected to the line via the
transformer, Pt= the rated voltage of the primary loop / the
rated voltage of the secondary circuit;
When the voltage is directly connected to the line, Pt shall
be set as 1.0.
