Scope

Main technical content: This document specifies the configuration and setting technical requirements for relay protection of the main transformer, regulating transformer, and compensation transformer in neutral point regulating transformers. This document is applicable to the relay protection configuration and setting of neutral point regulating transformers with voltage levels of 750 kV and above. In this document, the main transformer takes a phase-sharing autotransformer (high 2-medium 2-low 2) with 3/2 circuit breakers on the high-voltage side, 3/2 circuit breakers on the medium-voltage side, and a double branch single bus connection on the low-voltage side as an example. Other wiring methods can be implemented with reference to this example.
