Not established reliability indicator, three phase to three phase single component input-output phase relationship, wye-wye transformer winding connection type, fully inclosed inclosure type, 1 primary single component and 1 secondary single component winding function and quantity, 160.00 ac volts nominal single component single secondary and 174.00 ac volts nominal single component single secondary and 185.00 ac volts nominal single component single secondary winding operating voltage

A transformer consisting of one or more primary winding(s) and one or more secondary winding(s). It may be designed for direct connection to an alternating current source for purposes of changing the secondary volts and amperes or designed to eliminate metallic interconnection between circuits in an overall one to one voltage ratio, with or without additional output windings, or items designed to automatically maintain a constant output voltage within specified limits under varying input or load conditions. Also includes items having a provision for mechanically changing the turns ratio or inductive coupling in progressive increments by means of voltage taps, ratio adjuster, or devices oe similar design. For transformers having winding(s) common to both input and output circuits, see transformer (1), power, autotransformer. Excludes:transformer (1), pulse.
