The invention discloses a CT (Current Transformer) secondary circuit intelligent-detection method. The method comprises the following steps: 1) completing system initialization of a CT secondary circuit intelligent detector; 2) utilizing the CT secondary circuit intelligent detector to collect the phasor...
I see in the datasheet maximum output switch voltage for VCC's of 3 or 5, and all of the circuit examples show the transformer CT fed from the same voltage as VCC Is there any reason why I can't run the chip from 3.3V or 5V source and connect my primary CT to some...
Bar-type Current Transformer– This type of current transformer uses the actual cable or bus-bar of the main circuit as the primary winding, which is equivalent to a single turn. They are fully insulated from the high operating voltage of the system and are usually bolted to the...
