Due to the generator inertia, power plant transformers suffer harsher faults conditions than transmission and distribution
    transformers. Therefore, SERGI decided to investigate the explosion of a power plant step-up transformer to design a TP
    capable of preventing any kind of incident on any kind of transformer.

    In 2001, during this investigation, SERGI discovered for the first time that electrical arcs inside transformer oil could produce
    pressure gradients from 300 to 930 bar/sec (4,300 up to 13,500 psi/sec).
