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.

Answer:
Economists are important because they study a certain resource and figure out how to distribute it to others to get as well.
Explanation:
For example, An Economist might be studying a very scarce resource. This resource is something that is needed in everyday life. What an economist will do is find a way to make sure this resource is available to everyone. They could so this by creating another version of it or a different kind of it to distribute. Then they are helping the economy.
