Scope: This document specifies the terms and definitions, general requirements, test methods, and evaluation criteria for the through-current temperature measurement test of generator stator windings. This document is applicable to the quality inspection of electrical connections (welding or crimping connections) of stator bars in generators with exposed or hand-wrapped mica tape laminations at the stator nose ends, but it is not applicable to the quality inspection of electrical connections (welding or crimping connections) of stator bars in generators with insulated boxes at the stator nose ends or thick insulation directly cast into the stator bars. Main technical content: This standard primarily targets the hydraulic and electrical connections of stator bars in turbine generators and other welded joints. It will specify the requirements for the through-current temperature measurement test of generator stator windings, the test methods, and the evaluation criteria.
