EVS-EN 61986:2003

This standard applies to machines covered by IEC 34-1 when they cannot be loaded to a specific condition (rated or otherwise) for whatever reason. The methods are not suitable for machines of and below 1 kW. The object of this standard is to provide descriptions of various indirect load tests, the purpose of which is to determine the temperature rise of rotating electrical machines, including ac induction machines, ac synchronous machines and ds machines; both motors and generators are covered within the scope of the standard. The test methods in some cases provide in addition a means of measuring or estimating other parameters such as losses and vibration, but the methods are not designed specifically to provide such data. The proposed methods of test are considered equivalent, the choice of them relying only on the location, the testing apparatus and the kind of machine and the test result accuracy.
