Past meets present
As a part of a generator repair, the colleagues made an interesting discovery when dismantling the laminated core.
When this laminated core was manufactured in 1912, the manufacturer's employees had noted the date and time of day on the insulating paper. This insulation has actually survived 108 years. Today, the individual electrical sheets are no longer insulated with paper, but with a special insulating varnish.
