1 2050we convert 66kv to 33kv then 33kv to 11kv,11kv to 440v.why not we convert directly from 66kv to440v?
7 21036In any plant or substation main incommer voltage RY - 415 V,YB - 400 V, BR - 387 V(in commer feed from transformer 11 Kv /0.415 KV) why found voltage differance in each phase? plant have not self power plant it is depend on outsource grid
2 5491Here iam a question with SYNCHRONIZATION PANNEL related issue, as i want to design a SYNC.pannel board iam giving the 2 nos of 1MVA Generators to sync pannel , then what wil be the out put of the sync pannel, whether it wil be one cable coems from the sync panel or two cables.. as iam using two transformers to meet my load demand, so pls clear me whether two cables comes from sync panel to connect to transformers or only one cable

1- XC and the RC time constant are both measures of the reaction of C to a change in ____? 2-The power factor is a numerical ratio with a value between 0 and 1 equal to the ______________ of the phase angle. 3-When V and I are out of phase because of reactance, the product of V times I is called ______________ power 4-For _____________ inductors, the branch currents can be added algebraically. 5- The ______________ power in watts can be calculated as I^2R 6-Calculate XL with L = 30mH and f = 1kHz ( I have Xl=2piFL 2*3.141592653*1kHz*30mH =188 ohms Please check) 7-A parallel RL circuit has the values, R = 5kohms, XL = 5kohms. A voltage source of Vt = 10Vrms is connected in parallel to R and L. Determine the total current, It delivered by the voltage source Vt. 8-A series RC circuit has R = 1Mohm and C = 1microF. How long would it take for the capacitor to fully discharge if it is initially fully charged? 9-A circuit has real power = 300W and an apparent power of 500VA. Determine the power factor and phase angle. 10-The time constant for an LR series circuit is T = 0.1s and R = 10ohms. Calculate the inductance L.
