This standard specifies the principles, conditions, contents, methods, plans, and report requirements for the phase leading test of synchronous generators for grid connected operation. This standard is applicable to synchronous generator units operating in parallel with the grid. The phase advance tests of synchronous condensers and pumped storage motors can be carried out in accordance with this standard. The following normative references are essential for the application of this document. For dated references, only the dated version applies to this document. For undated references, the latest version (including all modified versions) applies to this document.
