We have studied about many techniques for finding the stability of system, ROOT LOCUS, ROUTH, BODE PLOT, POLER PLOT etc. In these which is used where. what are the difference among them... PLZ tell me.......
MSEB,
1660Why Ferranti effect is occoured in leading power factor load in a overhead transmission line?
1 4548This is reqd for a 1MW Solar power plant..We have 2DC outputs from the solar panels Connected to 2INVERTOR panels.. Output from invertor is 3ph,280v,500kva,50hz.These are connected to individual ACB.This has to be stepped up to 11KV ,1250KVA SYSTEM.Now can I use (1) one more ACBTO GIVE A COMBINED OUTPUT OF 1000KVA,280V & STEP UP THE OUTPUT BY USING a single two winding 3 ph transformer 11kv/1250kva. or (2)use the two outputs and connect to one three winding transformer of above rating..Pls suggestwith details.

During Starter Panel Com missing I Found The Main Incomer 40Amp MCB 10KA Trip When Motor Change Star To Delta Motor Rating 20HP BUT When We Use Same MCB To Other Motor It Does Not trip Or What Is Necessaries for Star Delta Starter MCB SFU MPCB OR MCCB And What are The Breaking Capacity of MCCB in the Motor above 15HP
A commercial Building is designed with 14th floor levels with indoor substation of three phase transformer with rated capacity of 1000 Kva.The transformer delivered 65% of its rated capacity at 0.67 power factor lagging.Because of low power factor, the power customer was penalized and certain cost was charged accordingly based on every point percentage lower than 85%.This situation may repeatedly happen on the succeding energy bills of power customer.The power customer is desired to improve its historical power factor of 0.67 lagging and no further penalty be impose by the local power company on the next bill. Q: Identify the appropriate solution you want to offer to Client?.Justify SCIENTIFICALLY and MATHEMATICALLY the principles behind the solution.
