Nettetf: Working frequency. The primary side inductance will be. L p = N p 2 A L = N p 2 μ c A c ℓ c. The primary side reactance will be. X p = 2 π f L p. The reflected burden resistor will be. R r = ( N p N s) 2 R b. In order your current transformer to work, these two conditions must be met: The reflected burden resistor must be much lower than ... NettetWhen the current transformer works, its secondary circuit keeps closed, therefore, the impedance of series coil of measuring instrument and protection circuit are very small, the working state is close to the short circuit. Current transformer consists of closed iron core and winding.
