Three-phase energy meter field calibrator
must be set correctly. The usual metering box is large when load current is designed,
current is not directly input to the energy meter, but is transformed by TA and sent to the
energy meter, where the transformation ratio to be set is the transformation ratio on the
TA nameplate. (If it is directly through the meter, the transformation ratio is 1:1; otherwise
it is input in accordance with the field TA transformation ratio).
For example: the voltage of a metering device is 220V, and the transformation ratio
of current TA is 500/5.
Press "↑, ↓" key to input the value 500 to the setting item before "/" set by the cursor
"transformation ratio", and then through "→" key, move the cursor to the setting item after
"/", and input 5 value as shown: Click "OK" to leave the setting
item.
