A high voltage porcelain insulator is tested at 50-Hz to find its equivalent circuit parameters using a high voltage Schering bridge as shown in the figure. The equivalent circuit of the insulator is shown as the first element (Rp and Cp). The capacitance Cs as the second element is 120 micro-F. The resistance in the fourth group R2 is 200 ohm. To balance the bridge, the resistance Ri as the third element and the capacitance in the fourth group C2 is adjusted to 410 ohm and 0.68 micro-F, respectively. Calculate the loss tangent of the insulator.
