Scope
Main technical content: This document specifies the working conditions, technical requirements, measurement and statistical methods for monitoring the neutral point current of transformers caused by stray current from DC traction power supply systems. This standard applies to neutral point grounded transformers with voltages of 110 kV and above. It is used for monitoring and statistics of DC bias caused by stray current from DC traction power supply systems. For other voltage levels of direct grounding systems, this standard can be used as a reference for implementation.
