Abstract :
We present the application of a waveform technique in determining the complex impedance of dielectric composite films at high AC voltages using a DAQ card and virtual instrumentation. Impedance characterization near dielectric breakdown conditions was performed for composites with enhanced dielectric properties. Dielectric hybrid materials made of organic resins and high dielectric constant modifiers under high AC voltages demonstrated fundamentally different behavior than the conventional fiber-glass reinforced epoxy resin laminates.
