Ahigh voltage Schering Bridge has the following arms with theircomponent ranges: AB: capacitor=100 pF to 500 pF, BC: variablecapacitance (1 nF to 2 µF) in parallel with variable resistancefrom (100 Ω to 1000 Ω), CD: variable resistance from (1 Ω to 1000Ω), DA: test object. Determine: (a) the maximum value of thecapacitance of the bushing, (b) the minimum value of thecapacitance of the bushing, (c) the loss angle of the bushing ifbalance is obtained with capacitance of the bushing is 200 pF,R4=1000 Ω, C4=10 nF with a high voltage capacitor having maximumvalue, and (d) in this question, what is the difference between thebushing and the test object
