WebIn other words, a transformer connected either Y-Δ or Δ-Y will exhibit this 30 o phase shift, while a transformer connected Y-Y or Δ-Δ will not. This phenomenon may be exploited by having one transformer connected Y-Y feed a bridge rectifier, and have another transformer connected Y-Δ feed a second bridge rectifier, then parallel the DC ...

WebFeb 22, 2024 · Thus the transformer couldn’t be used for DC then. Construction of the Transformer Basically, a transformer is made up of two parts which include; two inductive coils and a laminated steel core. The coils are insulated from each other and also insulated to prevent contact with the core. WebApr 8, 2024 · In a transformer, the magnetic flux created by the primary coil induces a current in the core. This occurs in order to oppose the charge that produced the magnetic flux (Lenz's Law). The currents flowing in the core are called eddy currents. These currents produce heat, using up energy and so causing inefficiency. WebSep 9, 2024 · We now know that for either AC or DC, long-distance power lines must transmit power at low current and at very high voltages because of the power wasted by either modus in high current transmission. But, as illustrated below, at long distances even at 400,000 volts, AC power lines, still waste far more power than do DC power lines. chicken corn soup with hard boiled eggs
