This part of IEC 61643 covers the application of surge isolation transformers (SITs) that are used in tele-communication transformer applications with signal levels up to 400 V peak to peak. These transformers have a high rated impulse voltage with or without screen between the input and output windings. SITs are components for surge protection and are used to mitigate the onward propagation of common-mode voltage surges. This document describes SITs´ selection, application principles and related information. This document does not cover power line communication transformers
