<CONFIGURE> Menu:
Transformer Polarity
The relative polarity between the Utility (Tertiary or TV)
winding and the Current Transformer (CT) must be speci-
fied in the <CONFIGURE> Menu Utility Pol: parameter.
This section describes the method for determining the
correct specification (NORM or REV) from examination of
the Regulator nameplate.

D.3.1
Single-Phase Regulators
D.3.1.1 Single-Phase Inverted Design Regulators
(ANSI type B)
The Utility transformer polarity is always normal for Single-
Phase
Inverted
Pol:NORM.
D.3.1.2 Single-Phase Straight Design Regulators
(ANSI type A) without forced air cooling
The Utility transformer polarity for Single-Phase Straight
Design regulators can be determined from the regulator
nameplate schematic diagram. The Utility winding taps
are labeled Un -- Ux, E2.
