Repair and overhaul of electric machines

What does this mean for the electrical engineering industry, service companies and maintenance engineers?

Since the beginning of November 2019, the new standard must be observed during the repair, overhaul and refurbishment of rotating electrical machines.

The standard now defines very precisely which work is to be carried out, especially from the point of view of testing technology. Also the how is described with many details. We are not allowed to publish passages of the standard here. However, it is advisable to purchase the standard in any case, e.g. from Beuth (publishing company) .

SCHLEICH has the suitable testing technology for the described test specifications!
