Why Current Transformer (CT) Seconday Should not be Open never open the secondary winding circuit of a current transformer while its primary winding is energized. Thus most of the current transformers have a short circuit link or a switch at secondary terminals. When the primary is to be energized, the short circuit link must be closed so that there is no danger of open circuit secondary.[email protected]

Transformers Part 2 - Beginners' Guide to Electronics current transformer with a ratio of 1000:1 will give an output current of 1mA/A of input current. If high currents need to be measured, the ratio may be higher or the burden lower - if 1,000A needs to be measured with output current appropriate for modern electronics, the burden could be reduced to 1 ohm, so 1,000A will give an output of 1A ...
