Common maintenance of capacitor impregnation tank

There are two types of varnish impregnation treatments: trickle impregnation, in which the coil is immersed in a tank of varnish (which serves as an insulating material), and vacuum impregnation, in which varnish is injected after the coil is subjected to a vacuum.
