HS-9503 Three Phase Isolated Current Transformer
Pic 1 the method of connection of isolated CT picture
When you test the return circle of three phase meter, the current and voltage are closed links, which you need to isolate them. As for the multi-position power meter auto-calibration system, it should add the three phase isolated current transformer: HS-9503.
At present, this kind of testing return circle current and voltage closed links power meter, and widely used in productive and application, even the numbers are still amplified. If the connection I-P of testing return circle can’t divided the current and voltage ,and through the circle it make the failed connection for every verified meters.
Therefore, the return current through the isolated transformer to separate , in order to improve the efficient of verifying and testing , as for the isolated connection energy meter, sometimes also hope testing them during the unisolated condition.
Phase should install the isolated transformer on each verified energy meter position.
The variable percentage of isolating transformer is 1:1, and phase place its error enough small range have in the whole range, can bring the obvious additional error in measuring.
• Wide electric current range:0.05A… 120A;
• Maximum transmission power: max. 60VA;
•Adopt the electronic error to compensate, guarantee accuracy;

Radiation the indicator lamp is shine: this circle is normal; otherwise the light is dim: it means that the circle is abnormal .
• PRO: warning the output outlet, I1, I2, I3 relevant current return circle output the warning signal (Lead the notice to export alertly) I1-I,I2-I,I3-I: isolated CT current input the terminal for one time.
• I1-COM,I2-COM,I3-COM isolated CT current input the terminal for primary.
• I1-o, I2-o, I3-o: isolated Ct current output the terminal for second time.
• COM1, COM2, COM3 isolated CT current output the terminal for second time.
• Several isolated CT connect the first time connect each other,and at second time to solo test the return circuit of power supply
