Compatibility Problem of TN and IT System in the Same Building

Article Preview

Abstract:

Compatibility of different wiring system in the same building is usually needed to guarantee security and flexibility. In this paper, the compatibility problem of TN and IT system is deeply researched. Firstly, the TN and IT system is introduced. Then three schemes of the TN and IT system compatibility are proposed based on transfer switch, insulating transformer and neutral point for earth isolation using zero-sequence reactor, which is used to realize the isolation for earth of the transformer neural point.
