- A Solid Dielectric Specimen Of Dielectric Constant Of 4 0 Shown In The Figure Has An Internal Void Of Thickness 1 Mm Th 1 (79.81 KiB) Viewed 52 times
A solid dielectric specimen of dielectric constant of 4.0 shown in the figure has an internal void of thickness 1 mm. The specimen is 1 cm thick and is subjected to a voltage of 80 kV (rms). If the void is filled with air and if the breakdown strength of air can be taken as 30 k V (peak/cm, find the voltage at which an internal discharge can occur. 80 KV (ams) Iim 王 Imm 10 mm A generating voltmeter is required to measure voltage between 15 kV to 250 kV. If the indicating meter reads a minimum current of 2 uA and maximum of 35 ua, determine the capacitance of the generating voltmeter. Assume that the speed of driving synchronous motor is 1500 rpm.
