IN SADC LOGIC ,oil dampers of CD and AB elevation open when OIL GUNS are taken in service perfectly, but when OIL GUNS are withdrawal they do not close on closings of HONV or LONV . HOTV and LOTV has to closed and again open then it gets close command. Needs checking , this observation is in both units please give opinion
SIR IN 250 MW BHEL TURBINE CONDENSER TUBES ARE MADE UP OF STAINLESS STEEL, WE HAVE VERY POOR VACUUM, DO YOU SUGGEST CHEMICAL CLEANING OF TUBES .WHAT IS YOUR EXPERIENCE
@@vibhanshu1 Firstly record condenser range at full load after that you can decide 1) whether it is cooling issue in condenser or IDCT ? 2.Also do check for air ingress in condenser. 3. Vacuum pump performance also check.
Those drives are connected to draw power at low frequency and low voltage will draw more current compare to normal current subsequently motor heating takes place, it necessary to correct voltage and drequency otherwise transmission line also streesed as current flow increases subsequently line heating takes place.
Excellent sir
@@worldinstrumentationengineer knowledge of other field also useful to all of us. I always value your dedication towards that.
Nice video Sir
Excellent content but please improve the audio quality
Ok

@@vibhanshu1 need to Throughly review LDO gun logic along with SADC logic.

Sir if Generator frequency or grid frequency low then what will happen to voltage & current
Those drives are connected to draw power at low frequency and low voltage will draw more current compare to normal current subsequently motor heating takes place, it necessary to correct voltage and drequency otherwise transmission line also streesed as current flow increases subsequently line heating takes place.
Sir why there's no lubrication provided to Generator exciter & PMG bearing?
