fotolec electrical components Germany fotolec model fotolec price
fotolec electrical components are instruments that measure by converting high primary current to low secondary current based on the principle of electromagnetic induction. A current transformer consists of a closed iron core and windings. Its primary winding has very few turns and is connected in series in the circuit where the current needs to be measured. Therefore, the full line current often flows through it. The secondary winding has more turns and is connected in series in the measuring instrument and protection circuits. When the current transformer is in operation, its secondary circuit is always closed, so the impedance of the coils connected in series in the measuring instrument and protection circuits is very small, and the current transformer's oper

When the current transformer is in operation, its secondary circuit is always closed, so the impedance of the coils in series with the measuring instrument and protection circuit is very small, and the operating state of the current transformer is close to a short circuit.
