Phase Degree of Response Voltage and Current Versus Excitation Voltage of the Accelerated Thermally Aged CSPE
- 9 Downloads
As the accelerated thermally aged years of CSPE samples increase, their resistivity and percent elongation decrease. On the other hand, their dissipation factors, glass transition temperatures, and apparent densities increase with increasing ageing times. The phase degree of response current versus excitation voltage of a CSPE sample decreased in agreement with the tendency of resistivity, while the phase degree of response voltage versus excitation voltage increased in agreement with the tendency of conductivity. The variations in temperature for an applied AC voltage are higher than those for a DC voltage.
