SCR circuit -In order to overcome surge voltage the
snubber circuit (capacitor & Resistor/Inductor )are used.

Answer / engbri

Self coimmutation is where a Thyristor switches of by its
own means, the snubber circuit is indeed there to overcome
surge voltage.

Answer / p.t. ramakrishna

Self coimmutation is where a Thyristor switches off by
applied voltage this is due to the revers voltage this will
happens only for ac applied voltage

Will it be OK to connect a 5MVA 33/6.6kV Ynd11 Transformer to a Star connected Motor. Or on other words connecting a Delta to a Star. I have another 30MVA 33/11 Dyn11 and would it be practical to convert it to Dd0 consequently converting the Voltage Ratio to 33/6.35kV Dd0.
