EA Elektro Automatik electrical components Germany EA Elektro Automatik model EA Elektro Automatik price

EA Elektro Automatik 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 measuring instrument and protection circuit are connected in series with the coil.
