Breakdown Voltage Behavior Under High Voltage and Frequency Signals on Isolating Solid Materials

The advance in technology demands higher levels on voltage and frequency acting over different materials, actually is not easy to found information about the behavior of the insulating materials under this conditions. Prototype for measuring the breakdown voltage for insulating materials has been developed at the Instituto Tecnológico de Veracruz for a high voltage and frequency testing. The equipment supplies a variable voltage from 0 to 12 KV at a given frequency or a fixed voltage for a variable frequency from 20 KHz to 50 KHz. Developing technology on isolation materials for high voltage and frequency is one of the approaches for this equipment. Knowing the real value of the breakdown point on isolation materials for high frequency signals, will help to develop more safety equipments. Preliminary tests for different isolating materials sampling are presented in this paper.
