IEC 60034-19:2014 applies to d.c. machines rated 1 kW and above operating on rectifier-fed power supplies, d.c. buses or other d.c. sources and provides standardized methods intended to determine characteristic quantities for conventional and rectifier-fed d.c. machines. These methods supplement the requirements in IEC 60034-1 and IEC 60034-2-1. The main changes with regard to the previous edition are as follows: – description of the procedure for black band testing has been detailed and clarified; – procedures for measurement of the magnetization curves under no-load and load conditions have been added.
