Q29. Following measurements are made for a test specimen with a 7 kV rms supply at a frequency of 6 kHz: The air capacitance of the electrode system - 30 nF with negligible loss angle. The capacitance and loss angle of the electrodes with specimen are 130 nF and 0.0066 respectively. Assuming there is no additional stray capacitance, determine the dielectric loss factor A) 0.975 pEin B) 0.253 pF/m C) 0.624 pF/m D) 0.080 pF/m Q.30. A solid dielectric exposed to high voltage in a laboratory to determine its mechanical breakdown strength. The dielectric has 0.97 GPa Young's modulus and relative permittivity 2.2. If the breakdown occurs when the applied voltage reaches 13 MV, determine the initial thickness of the dielectric A) 3.07 mm B) 3.32 mm C) 2.57 mm D) 2.82 mm
