Designation of voltage ratings

E shall indicate a winding that is permanently

Δ-connected for operation on an E volt system.

E1GrdY/E shall indicate a winding that has

reduced insulation and is permanently

Y-connected. The neutral end may be connected

in the tank or brought out and effectively

grounded for operation on an E1 volt system

with E volts available from line to neutral.

V × V1 shall indicate a winding, the sections of

which may be connected in multiple to obtain

one of the voltage ratings of V, or may be

connected in series to obtain one of the voltage

ratings of V1. Windings are permanently Δ- or

Y-connected.

E1Y/E shall indicate a winding that is

permanently Y-connected with a fully insulated

neutral brought out for operation on an E1 volt

system, with E volts available from line to

neutral.
