A series resistance (ESR), also known as internal resistance, measures the loss of useful energy in a simple electronic circuit with a resistor and an ideal (perfect) capacitor, and its resistance is 500mOhm.In this capacitor's case, the dissipation factor 12 % represents the power loss caused by AC applied through it.The tan delta of the insulating oil is 0.12 based on its electrical dielectric test.
