12.9.13 Capacitance and DF Measurement
Capacitance (C) and Dissipation Factor (DF) measurement is an established
and important insulation diagnosis method which was first published by
Schering in 1919 [9] and utilized for this purpose in 1924. In a simplified diagram
of the insulation C

represents the capacitance and Rp the losses (Figure
