DG B-check,C-Check,D-check is depending upon the running
hrs.If the running hrs is not reached as mentioned.How to
conduct the DG checks.
Answer Posted / biswajeet
the checks are depend on the running hrs. if it is not
reached means engine is not running ok.you can wait till the
running hrs reached. if the stoppage is long you can go
according preservation requirement by the manufacturars

I have made a 3 phase thyristor full bridge rectifier. But at the moment it is working only for the half bridge operation. Both the half bridges are on operation separately but when i put it into full bridge operation the oscilloscope output is zero. I rechecked that the pulses are correct for each thyristor. what could be the possible reason for this?
