GOMEZ, S.; BUITRAGO, M.P.  e  ROLDAN, F.A.. Portable High Voltage Impulse Generator. Ing. Investig. [online]. 2011, vol.31, suppl.2, pp.159-164. ISSN 0120-5609.

This paper presents a portable high voltage impulse generator which was designed and built with insulation up to 20 kV. This design was based on previous work in which simulation software for standard waves was developed. Commercial components and low-cost components were used in this work; however, these particular elements are not generally used for high voltage applications. The impulse generators used in industry and laboratories are usually expensive; they are built to with stand extra high voltage and they are big, making them impossible to transport. The proposed generator is portable, thereby allowing tests to be made on devices that cannot be moved from their location. The results obtained with the proposed impulse generator were satisfactory in terms of time and wave forms compared to other commercial impulse generators and the standard impulse wave simulator.

Palavras-chave : Electrical insulation; voltage impulse generator; insulation coordination; power disruption; standardised waves; standardised wave simulator.
