抄録

The pulsed electroacoustic (PEA) method has been used to measure space charge distributions in insulating materials. A high-resolution PEA measurement system and signal procedure have been reported in previous papers. Since the signal procedure is necessary for high-resolution measurement, the system must include a computer. A new PEA system without a signal procedure or computer is introduced here. In order to eliminate signal distortion, a step-voltage generator is used in the new system instead of a very narrow pulse generator used in conventionally ones. The resolution of the system is 24 microns, which is lower than that of conventionally systems. The poor resolution can be improved by changing the pulse waveform according to numerical simulations. The new system should be used in portable measurement equipment.
