... for a time lasting between 10 ms and a few seconds (see fig. 1 ). When power is off (100 % voltage drop), for 1 s to 1 min, we talk of a “short interruption”, and of a “very short interruption” between 10 ms and 1 s. When duration is i 10 ms, the interruption is normally due to “transient” or volunt ...

... sectioned windings can significantly effect the magnetizing inductance produced. When winding transformers, it is cheapest and most easily repeatable to wind a typical ETD type transformer (rather than a torroid) in such a way that coupling is maximised, -in other words, use either bifilar windings, ...

Transformer types
A variety of types of electrical transformer are made for different purposes. Despite their design differences, the various types employ the same basic principle as discovered in 1831 by Michael Faraday, and share several key functional parts.
