Current transformer (CT) saturation classification using empirical mode decomposition (EMD) and relevance vector machine (RVM)

CT saturation is a major problem in the current scenario. It occurs due to the core reaching the highest magnetic flux. This happens due to a very high primary current. The detection of CT saturation ...

Testing Current Transformers with 'the Modeling Concept'

Omicron has introduced a way to test current transformers at all lifecycle stages by using a testing method called "the modeling concept". The "traditional" way of testing a current transformer is to ...

Current Transformer AC Load Indicator LED

A current transformer (CT) is a simple, practical and inexpensive means of detecting the presence of AC current. Detecting load current rather than applied voltage is a superior method of determining ...

Current transformer as inexpensive, non-invasive timing trigger

We needed to detect motion in a commercial, stepper motor driven system and subsequently initiate motion in a servomotor based system we developed. Because both systems simulate human respiratory ...
