In a power system we know that if the generated power is less than the load then the frequency of the system is decreases.So does this mean that total required load is delivered at alower frequency?

1967An 11kv system consisting of an underground cable to a sub station about 300 meters away was shut down for about 10 hrs. On energising, it tripped off on earth fault about 10---20 mins later 6 times but since than it is not tripping.its already 3 weeks now. The SPAJ was found to be fine. what could be the cause.No test had been done to determine the cause of the trippings till now because of demand.
2 4561DEAR SIR, HOW TO CALCULATE WELDING TRANSFORMER CAPACITY IN KW OR KVA (POWER). TWO WELDING TRANSFORMER USED WHAT TYPE OF DG SET CAPACITY LIKE ( 45 KVA OR 62.5 KVA), PLEASE TELL THE WELDING TRANSFORMER RATEINGS. I AM REFINARY (TANKS WELDING) THANKING YOU
2 10001In a generator (Synchronous) does the rotor speed (frequency) corresponds to the speed of the water (in hydro). does the torque on the turbine relate to the flow of water?
2 4363When in a large power system if the demand of power is larger than the generated power the frequency of the power system drops.(assume the rated frequency is 50Hz and now it is 49Hz) So does this mean the demand is totally supplied with a lower value of generated power in a lower frequency?
1 3377How can decide the MVA rating of power transformer for substation like 220/132, 132/66, 66/33kv etc or even higher kv rating of substation???? Send me the strictly technical answer that shows your strong technical aptitude.
