WAVE SHAPING CIRCUITS

Answer / tharan

diode used in rectification.. elctornics compenent used in pcb board... like electronics application.... two end one anode and cathode....

Answer / naveen joshi

Diode is semiconductor (p-n)material switch which allow to 

flow current in one direction (reverse or forward) and

change the waveform current AC to DC.

The capacity of the transformer is 20/25 MVA, Ratio is 132/11 KV, Vactor group YNyno. and impedance is 10.07%. As per the calculation the secondary current is 1312.2Amps. The maximum fault current the transformer should sustain is 13.030KA. How many times the transformer should sustain the maximum short circuit current of 13.030KA over a period up 1 Year. The transformer is repaired one & 10 Years old.
