Delcon electrical components Germany Delcon model Delcon price

Delcon electrical components are instruments that convert high primary current to low secondary current for measurement 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 current of the line often flows through it. The secondary winding has more turns and is connected in series in the measuring instrument and protection circuit. When the current transformer is in operation, its secondary circuit is always closed, so the impedance of the measuring instrument and the protection circuit series coil is very small, and the current transformer operates.
