Shunting a current transformer
A current transformer (CT) is a type of transformer that is used to reduce or multiply an alternating current (AC). It produces a current in its secondary which is proportional to the current in its primary. Current transformers, along with voltage or potential transformers, are instrument transformers. Instrument transformers scale the large values of vol… http://www.metersusa.com/Transformers/Data/CTTheory.pdf

Webwelding current and a shunting current, I W and I S, respectively. These two currents, and therefore the amounts of heat, are de-termined by the relative values of the re-sistances along the shunting and welding paths. An estimate of these resistances is helpful for assessing the amount of elec-tric current and, therefore, heat, diverted WebThe Indian locomotive class WCAM-2 is a class of dual-power AC/DC series electric locomotives that was developed in 1995 by Bharat Heavy Electricals Limited used in the Indian Railways system.
