Current Transformer 1:1500 , 10A/6.66mA

Type : Current transformer


Working principle 

Principle of current transformer is based on the principle of electromagnetic induction. The current transformer is composed of a closed iron core and a winding. The primary winding turns is less and connected in series in the circuit to measure the current, so it often flows all current in circuit; Secondary has more windings and connected in series of measuring and protection circuit. When current transformer is in operation, the two- loop is always closed. Therefore, measuring and protecting loop-circuit impedance in series with the coil current transformer is very small, close to the state of short circuit.
