On what basis Friability limit NMT 1.0%w/w is recommended. what is impact on formulation if this limit exceeds.694
1) why a dg set shows variation of power factor and load when synchronised with other dgs? 2)Why the load sharing is not become equal in all dgs?. 3)When a dg set will not run on auto start?

Hi All, I Want To excute scripts batch without using QC .I need code for that Thanks Balaji
1.why should we connect the measuring instruments in l.v side in short circuit test of a transformer? 2.why the power factor is less in open circuit test of a transformer?
A 7 storey building has a floor area of 35,000sq.ft on each storey. On the ground floor 11KV electrical sub-station is to be erected. A load of 3kw for every 400sq.ft (p.f is 0.8) is proposed for each floor. fire pump 7.5hp, water pump 5hp, lift 2 nos, each 10hp and 20shop load of each shop is 5kw. calculate a. load each floor b. total load of building c. L.T feeders for aech floor and from transformer to main. d. distribution diagram e. capacity of sub-station/capacitor bank f. line diagram
