How to Calculate Derating factor of series connected thyristor string?
Derating factor of series connected thyristor string calculator uses Derating factor of thyristor string = 1-(Resultant series voltage of thyristor string/(Number of thyristors in series thyristor string*Worst case steady state voltage of thyristor 1)) to calculate the Derating factor of thyristor string, The Derating factor of series connected thyristor string formula is 1 minus the string efficiency of the series combination. Derating factor of thyristor string is denoted by DRF symbol.
How to calculate Derating factor of series connected thyristor string using this online calculator? To use this online calculator for Derating factor of series connected thyristor string, enter Resultant series voltage of thyristor string (V_{s}), Number of thyristors in series thyristor string (n_{s}) & Worst case steady state voltage of thyristor 1 (V_{DS(max)}) and hit the calculate button. Here is how the Derating factor of series connected thyristor string calculation can be explained with given input values -> 0.333333 = 1-(20/(3*10)).
