Transformer bushings may be specified with extra creepage distance and higher than standard BIL ratings, if required by local conditions or users' practices. Protecting the transformer windings from high-voltage surges with surge arresters will allow the use of a transformer with a lower BIL and still provide for better performance.

Determine the ampacity of each current-carrying conductor given the MC cables with more than 20 current-carrying conductors being bundled. From Table 310.15(B)(16): Because the actual calculated load is 16 amperes of continuous load, 210.19(A)(1) is applicable. The conductors must have an ampacity equal to or greater than the load before the ...

Station service transformer ratings are specified by the kVA rating, transformer primary and secondary voltages, the short circuit rating and the BIL rating. Transformer KVA and Voltage Rating: The capacity of a transformer is determined by the amount of current it can carry continuously at rated voltage without exceeding the design temperature.

34,500V Grounded Wye primary with +/- 2, 2 ½% taps with 150 kV BIL Rating. Note that when the grounding transformer is located within the collection substation, and the collection substation voltage is maintained at 34,500V by the main power transformers on-load tap changer, the +/-2, 2 ½% grounding transformer taps are not required.
