These transformers are used to measure currents of 50 ÷ 60Hz from 25A to 600A
(nominal primary current). The peculiar characteristic of these transformers is the high
number of secondary turns. This provides a very low secondary current, suitable for an
electronic measurement circuit. The secondary current may be detected as voltage on
a resistor.
