NANOPROTECH electrical components Germany NANOPROTECH model NANOPROTECH price

NANOPROTECH 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 with the circuit where the current needs to be measured. Therefore, the full current of the line often flows through it. The secondary winding has many turns and is connected in series with measuring instruments and protection circuits. 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 trans
