Abstract :
This paper presents possible transient states related to vacuum circuit breaker operation in PV power plant. Case study of transformer de-energization under no-load conditions was analyzed. The variation with respect to up-to-date studies is related to determination of solar converters LC filters influence on multiple arc re-ignitions occurrence during vacuum circuit breaker operation. Research covers both laboratory measurement as well as PSCAD simulations.
