The Model EZCT-10
is a
microprocessor-based, current-transformer test set. This rugged and
portable test set measures excitation current, turns ratio and
winding polarity on single- and multi-ratio current transformers.
Current transformers can be tested in their field-mounted
configuration, eliminating the need to remove bushings or current
transformers from the host equipment.
Ratio and
Polarity Test
The EZCT-10TM
determines the
current-transformer turns ratio by accurately measuring the voltages
across the primary and secondary windings (a direct proportion) and
then displaying the voltage ratio. Turns ratio is measured from 0.8
through 5,000 to 1.0 with an accuracy of 0.5% or better. Winding
polarity displays as a + or - sign and is also annotated with the
phase in degrees.
