Components for low-voltage surge protection - Part 352: Selection and application principles for telecommunications and signalling network surge isolation transformers (SITs)

IEC 61643-352:2018 covers the application of surge isolation transformers (SITs) that are used in telecommunication 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.

Note: This document does not cover power line communication transformers.
