Dry Cell Transformer

Product Introduction: The percent impedance is the percent voltage required to circulate rated current flow through one transformer winding when another winding is short-circuited at the rated voltage tap at rated frequency. For a two winding transformer with a 5% impedance, it would require 5% input voltage applied on the high voltage winding to draw 100% rated current on the secondary winding when the secondary winding is short-circuited. If 100% rated voltage is applied to the high voltage winding, approximately 20 rated current would flow in the secondary winding when the secondary winding is short-circuited.
