Model 109 – Wound Primary
Model 190X – Auxiliary Transformer
MODEL 190
The Model 190 is a low ratio wound primary current transformer, suitable for primary
currents up to 50 amperes. The table below lists the most common current ratings.
MODEL 190X
ANSI Metering Class: 0.3 B0.5
The Model 190X is an auxiliary transformer for use in the secondary of main current
transformers to change the ratio for metering applications. Since the Model 190X is used in
the secondary of another current transformer it has no voltage rating. It is given a 2500
Volt 60Hz high potential test. It is designed to be used on circuits not to exceed 600 Volts
to ground or between windings.
** The circuits of up to five secondaries may be totalised. Equal or unequal line current
