Product description

There are C.Ts.Which are interposed between the main C.T.and the burden(Load)so that the secondary current of the main C.T. is adjusted as required by the burden.When used in providing transformer differential protection,these C.Ts are also used to correct the phase shift,which may result due to particular method of connection used for the transformer windings. The main fuction of an interposing CT is to balance the current supplied to the relay or others where threre would otherwise be an imbalance due to the ratios of the main CTs.Interposing CTs are equipment with a ratio that can be selected by the user to achieve the balance required. As the name suggests,an interposing CT is installed betweenthe secondary winding of the main CT and relay.They can be used on the primary side or secondary side of power transformer being protected,or both interposing CTs also provide a convenient method of establishing a delta connection for the elimination of zero sequence currents where this is necessary.
