IntroductionThis method@ which allows the measurement of winding resistances to be made without interrupting the on-load test and@ therefore@ without having to make extrapolations@ is applicable to low-voltage or high-voltage machines of any power rating.The methods of measurement contained in this Report are typical only@ and the Report is intended solely for experimental use with a view to gaining experience.? For this reason@ it will be necessary to establish the accuracy and consistency of the various methods.The values of temperature obtained by the methods contained in this Report may in many cases be from 5? to 25? C higher than those obtained by existing standard methods.? It will@ therefore@ not be practicable to employ the methods of measurement contained in this Report in conjunction with IEC Publication 34-1@ Rotating Electrical Machines@ Part 1: Rating and Performance.? During experimental use of this method of measuring temperatures@ it will also@ therefore@ be necessary to establish what temperature rises can be permitted.?
