The number of houses that can be powered by one electrical transformer drum depends on factors like the power capacity of the transformer and the electricity demand of each house. Generally, a transformer drum can typically supply power to several houses within a neighborhood or a small area. It's important to consult with an electrical engineer or utility provider for an accurate assessment for a specific location.
A 22VA transformer has a power rating of 22 watts. VA (volt-ampere) is a unit used to measure the apparent power in an electrical circuit.
To determine how many 3-watt bulbs can be powered by a 500VA transformer, divide the VA rating of the transformer by the wattage per bulb: 500VA / 3W = 166.66 bulbs. In this case, you can power approximately 166 bulbs with a 500VA transformer.
The weight of a drum can vary depending on its size and material. However, on average, a standard drum could weigh around 15-25 kilograms.
You can tap off approximately 833 200 amp panels from a 250 kVA transformer. This calculation is based on dividing the kVA rating of the transformer by the current rating of the panel.
A 150-gallon drum contains 0.0036 gallon per cubic inch.
