A current transformer reset circuit, which uses two separately controlled operational parts to reset a current transformer. The first operational part is a current source used to generate a reset current. The second operational part is a reset switch, which when turned on allows reset current to ...
PURPOSE: To obtain a current-transformer circuit which increases the reliability of an apparatus by a method wherein positive DC power supplies and negative DC power supplies are installed at a plurality of current transformers and the current conduction polarity of a current- transformer primary curr...
Apparatus for determining the size adequacy of a current transformer in an electrical power distribution system. The apparatus includes a voltage generating source for connection in series with a current transformer secondary circuit, which source saturates the current transformer. A first signal is provi...
Bar-type Current Transformer –This type of current transformer uses the actual cable or bus-bar of the main circuit as the primary winding, which is equivalent to a single turn. They are fully insulated from the high operating voltage of the system and are usually bolted to the current-carr...
