HS-9503 Three Phase Isolated Current Transformer
Technical Specifications
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.
