Description: Selecting, sizing transformers for commercial buildingsJun 09, 2011Transformer size in kVA = 42 kVA x 1.25 = 52.5 kVA. Therefore, a 75 kVA transformer would be selected for this application out of the available standard ratings for a 480 V primary to 208 Y/120 V secondary. The most common building industry standard ratings are 3, 6, 9, 15, 30, 3 ...

    Power Solid State Devices from Bias Tap. This is the standalone power supply used above. It takes power from the power transformer's 40v AC bias tap and converts it to +16v and -16v to power solid state devices (transistors and chips) in your tube amplifier. The power circuit will work with an input voltage between 30 to 60 volts AC RMS and still put out +/-16 volts DC.

    Bunding Oil Filled Transformers To Bund or Not to Bund mayotte transformer tank building volume

    Apr 25, 2019Matthew Pilgrim Senior Consultant Engineer (FM Global). Carl, in general transformer bunding is a good idea, but can be a costly exercise for existing installations. Factors to consider are the cost and lead time of the transformer, its impact on production, whether an oil fire would expose adjacent transformers or buildings and the type of oil used (mineral oil, natural or synthetic esters).Bunding and Spill Management Guidelines5.4.1 Tank storages The designed net capacity of a bunded compound in a tank storage facility should be whichever is the largest of the following At least 110% of the volume of the largest storage vessel; or At least 110% of the combined volume of any inter-connected vessels within that bunded area; orBunds and secondary containment - GPT EnvironmentalThe 110% rule is applicable where there is only 1 container stored inside the bund, in this situation the calculation is simple, the bund needs to have a capacity of at least 110% of the primary containment volume. For example if a tank has a capacity of 10,000 litres the bund
