AC CURRENT TRANSFORMERS FOR MONITORING AND PROTECTION APPLICATIONS

The VAC type series for AC current transformers comprises various versions for a large number of applications.

AC current transformers are used to record sine or rectangular alternating currents in the frequency range of 16 2/3 to 1000 Hz. Highly permeable core materials with a high saturation induction are preferred for this.
