Għaliex jista''t il sekondarju naħa ta' il kurrent transformer be open?

1. The original current is determined by the detection circuit. When the load resistance is different, the initial current is different. In normal operation, the secondary pole of the current transformer is short-circuited equivalently, and the demagnetization effect of the current is the demagnetization effect of the current is very strong, that is say, in the initial position, the initial position, the magnetomotive force of the secondary pole is similar. As a result, the directions are reversed, so the required resultant magnetic potential and corresponding excitation current is small.
2. If the second side of the current transformer is skonnettjat, the original current will all become excitation current, increasing the magnetic flux of the iron core, the iron core, the iron core the iron core be oversaturated, and the iron consumption will increase sharply, causing the transformer to heat and damage. At the same time, the large number of turns in the secondary winding will induce dangerous high voltages, endangering the safety ta' operaturi u kejl tagħmir.
