    Tips: Current Transformer Working Principle

    Working principle of the current transformer is based on the electromagnetic induction principle, circuit current often flows through its primary winding. When 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. It has few primary winding that are connected in series in the current circuit under measurement; however, it has many secondary winding, which are connected in series in the measuring instrument and protection circuits. The current transformer plays the role of converter and electrical isolation, it’s a sensor for measuring instrument, relay protection and other secondary equipment to obtain current information of primary circuit in power system. It converts the high current to a low current by ratio, its primary end is connected with the primary system, while the secondary end is connected with the measuring instrument and relay protection.

    There are two methods for the installation of CT, one is that it can be installed with busbars, and the other is that it can be installed using a bottom plate. (we shall proivde the bottom plate)
