Indian Transformers & Electricals ( A Unit Of Patni Enterprises Private Limited) - Power Transformers, Special Transformers & Distribution Transformers Manufacturer from Jaipur, Rajasthan, India
Aug 22, 2018 · Again, if the source voltage is 11 kV and load is to be fed by 415 V, then the rating of transformer will be 100 kVA, 11 kV / 451 V. But if we know the voltage and corresponding current in HV / LV side of Transformer, then we can calculate the rating of transformer by using the simple formulas as below: The 500KV power transformer manufactured by us has all kinds, and is steady performance, whose technical performance index is on forefront status for entire Chinese transformer industry, which has following advantages: reasonable structure, reliable insulation, low loss, low PD, low temperature rise and low noise level, strong short-circuit withstand ability, strong lighting impulse withstand ...

Summary. Dominion Virginia Power’s Suffolk Substation was Burns & McDonnell’s first work on Dominion’s 500-kV transmission system. This project expanded the substation to accommodate a new 500/230-kV, 840MVA transformer bank, two new 500-kV circuit breakers, one new 230-kV low side breaker and all associated auxiliary equipment.
Nov 17, 2019 · A power transformer requires various routine maintenance tasks including measurement and testing of different parameters of the transformer. There are two main types of maintenance of transformer. We perform one group on a routine basis (known as preventative maintenance), and the second group on an ad-hoc basis (i.e. as required). Alfa Transformer offers new, energy efficient, single-phase and three-phase low voltage (600V class) and medium voltage dry type transformers from 0.05 KVA to 5000 KVA. Reconditioned dry type transformers are available from 1 KVA to 2500 KVA. New, energy efficient, oil filled transformers, single-phase and three-phase. – a 3-phase, 1300 MVA, 24.5 kV / 345 kV, 60 Hz generator step-up transformer has a leakage impedance of 11.5% • determine the equivalent circuit of this transformer on a per-phase basis • calculate the voltage across the generator terminals when the high voltage side of the transformer delivers 810 MVA at 370 kV with a 0.90 lagging power ...
