These transformers are used to measure current at 50 ÷ 60Hz from 25A at 600A (rated
primary current lp). The special characteristic of these transformers is the high number
of turns of the secondary (ls). This produces a very low secondary current, appropriate
for an electronic measurement circuit. The secondary current can be read as voltage on
a resistor.
