Answer / vimal patel

You have to find that polarization index for insulation level which is depend on Voltage level and some other parameter so refer some reference for it like wikipedia for it...

A resistance, inductance & capacitance are connected in series between points A & B.The voltage drops across the resistance,inductance&capacitance are found to be 40V,70V&100V respectively. What is the total voltage between between points A&B (Vab)? a)210V b)70V c)50V d)230V

Hi, I've just got into my electrical engineering course and I need some help with a question of mine here. During a site visit, we were shown a main LT panel which has switchgears, ammeters and different kinds of relays and the distribution network from that panel. In the main LT panel I've noted down the current readings as Ir - 163A, Iy - 150A and Ib - 147A. The Line to Line voltage is 415 V at 50 Hz and Line to Neutral voltage is 230V at 50 Hz. From the above details, how would I calculate the kVA rating of transformer? The primary side voltage of the transformer is 11 kV and the secondary side voltage is 415V and the frequency is 50 Hz.
