In an experiment a solid ceramic insulator is subjected to a voltage of 30 kV (AC-peak) at 50 Hz. The ammeter connected to the
insulator in series shows a current of 17.3 mA (AC-peak). If the dissipation factor of the insulator is 0.0005, find the dielectric
loss of this insulator in this test if ionization and polarization losses are fully ignored. Assume that the insulator is modelled as a
series combination of a resistance and a capacitor.
