The continuous neutral-current rating be for an autotransformer used to create a three-phase, it must be sufficient to handle the maximum possible neutral unbalanced load. 450.5.
<h3 /><h3>What is meant by autotransformer?</h3>
A grounding autotransformer is used to create a three-phase, 4-wire distribution system from a three-phase, 3-wire ungrounded system.
A three-phase autotransformer is a special type in which common winding is shared by the high voltage and low voltage. Three-phase AC is supplied at primary and output is collected at secondary. Three phase autotransformer is used for such applications where a small voltage is used in the distribution system.
Autotransformers are frequently used in power applications to interconnect systems operating at different voltage classes, for example, 132 kV to 66 kV for transmission. Another application in industry is to adapt machinery built (for example) for 480 V supplies to operate on a 600 V supply.

Of all the ancient calendar systems, the Maya and other Mesoamerican systems are the most complex and intricate. They used 20-day months, and had two calendar years: the 260-day Sacred Round, or tzolkin, and the 365-day Vague Year, or haab. These two calendars coincided every 52 years.
The correct answer for the question that is being presented above is this one: (a) elastic demand. The measure of how demand changes after price adjustments is called elastic demand. T<span>he percentage change in quantity demanded is smaller than that in price. Hence, when the price is raised, the total revenue increases, and vice versa.</span>
