Witryna17 lip 2024 · Time interval between shots during lightning impulse testing was prolonged as suggested by published research on ester dielectric testing, as well as resting time between different voltage tests [6, 7]. Prototype transformer retro filled with synthetic ester was successfully tested. Witryna1 sty 2024 · Power transformer winding model for lightning impulse testing. This paper presents a method for calculating the internal voltage transients useful for power transformer winding modelling. The method is based on lumped parameter model of a transformer winding and the transient response is obtained using time-domain analysis.
