Da handbook …The DC-component can lead to saturation of current measurement transformers, thus giving out false secondary signal to protection relays. Figure 3.25: Inrush current of a 16 MVA 63/11 kV power transformer 3.15.3.4 Magnetising Current As stated earlier, the magnetizing current at the rated voltage is very small, around 1% out of the rated current.

Instrument Tranformers - SKF KSKEF has a top core design with composite insulator for voltages up to 420 kV. It is designed to provide both current and voltage measurement from a single device and uses the same components as the individual CTs and VTs. The primary coil for the VT and the core box of the CT are both housed in the head, on top of the insulator.

Unit 6 Transformershome.agh.edu.pl/~potrec/Electrical Engineering...· PDF fileA current transformer should always be short-circuited when not connected to an external load. Because the magnetic circuit of a current transformer is designed for low magnetizing current when under load, this large increase in magnetizing current will build up a large flux in the magnetic circuit and cause the transformer to act as a

Current Transformer : Construction, Working, Types and Its ... Transformer Device Working Principle. The working principle of the current transformer is somewhat different when we compare it with a normal voltage transformer. Similar to the voltage transformer, it includes two windings. Whenever AC supplies throughout the primary winding, then alternating magnetic flux can be generated, then AC will be induced within the secondary winding.
