Current Transformer Definition Electricity

Is a type of instrument transformer that is designed to produce an alternating current in its secondary winding which is proportional to the current being measured in its primary current transformers reduce high voltage currents to a much lower value and provide a convenient way of safely monitoring the actual electrical current flowing in an ac.

Current transformer definition electricity.

A current transformer ct is a type of transformer that is used to reduce or multiply an alternating current ac. 100 a 5 a. Current transformer ratings rated primary current ipn rms value of the maximum continuous primary current usual values are 25 50 75 100 200 400 600 a. This is the second coil in the diagram above.

The winding which gives the desired output voltage due to mutual induction is commonly known as the secondary winding. Rated transformation ratio kn i rated primary i rated secondary e g. The current transformer c t. Transformer operates on an ac supply.

This is a very basic definition of transformer since there is no rotating or moving part so a transformer is a static device. It transforms the high voltage current into the low voltage current due to which the heavy current flows through the transmission lines is safely monitored by the ammeter. Electrical energy can be transferred between. Current transformer ct definition.

A power transformer is a static machine used for transforming power from one circuit to another without changing frequency. Transformer device that transfers electric energy from one alternating current circuit to one or more other circuits either increasing stepping up or reducing stepping down the voltage transformers are employed for widely varying purposes. The transformer is the static device which works on the principle of electromagnetic induction it is used for transferring the electrical power from one circuit to another without any variation in their frequency. A transformer is a passive electrical device that transfers electrical energy from one electrical circuit to another or multiple circuits a varying current in any one coil of the transformer produces a varying magnetic flux in the transformer s core which induces a varying electromotive force across any other coils wound around the same core.

A current transformer is a device that is used for the transformation of current from a higher value into a proportionate current to a lower value. Alternating current abbreviated ac pushes the electrons back and forth changing the direction of the flow several times per second in the united states the current changes direction at a rate. E g to reduce the voltage of conventional power circuits to operate low voltage devices such as doorbells and toy electric trains and to raise the. Rated secondary current isn this is equal to 1 a or 5 a.
