Current transformer
inputs, 5A-AC
Connect the generator current transformer
terminals to these inputs. Do not connect the
same current transformer to other instruments
otherwise a unit fault will occur. Connect each
terminal of the transformer to the unit‟s related
terminal. Do not use common terminals. Do
not use grounding. Correct polarity of
connection is vital. If the measured power is
negative, then change the polarity of the
current transformer. The secondary winding
rating shall be 5 Amperes. (For ex. 200/5
Amps).
