power systems loss

Typical Loss for Amorphous-Metal Core Distribution Transformers. The losses shown in the table are the typical values of a amorphous-metal cored distribution transformers. Core loss and Winding loss (watts) varies relatively as with the increase of the distribution transformer's kVA capacity. Also shown are he respective kilo-watthour loss in annual basis for different transformer capacity in 30% and 40% load factor. Annual kwh are based on peak transformer kW loading equal to kVA size.

Typical Loss for Silicon-Core Distribution Transformers The losses shown in the table are the typical values of silicon-cored distribution transformers. Core loss and Winding loss (watts) varies relatively as with the increase of the distribution transformer's kVA capacity. Also shown are he respective kilo-watthour loss in annual basis for different transformer capacity in 30% and 40% load factor. Annual kwh are based on peak transformer kW loading equal to kVA size.

Typical No-Load loss and Load loss for Power Transformers according to MVA capacity. No-load loss and Load loss in Power Transformers varies significantly depending on different factors. Here you can find the typical value for the no-load loss and load loss according to power transformers having Load Tap changers and those having none. Different MVA capacity means also having different values for the power transformers' no-load and load loss.

Classes of incandescent lamps as cataloged by the manufacturers.   Large lamps, miniature lamps, and photographic lamps are the three major groups of incandescent lamps as divided and cataloged by the manufactures. As a summary, large lamps are those normally used for interior and exterior general and task lighting. Miniature lamps are generally used in automative, aircraft, and appliance applications. Photographic lamps, as the name implies, are used in photography and projection service.

Short Comparison between using wooden arms vs. steel arms in power transmission system. Wooden crossarms used in power transmission system are lower in cost than steel arms of the same strength and, aside from the shorter life, the possibility of being shattered by lightning, and the risk of burning due to leakage current at 345kV and above, are satisfactory. On wood pole construction, the advantages of steel arms - resistance to lightning damage and longer life - are not usually sufficient to offset the insulation strength of wood crossarms.
