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.

Explanation:
Psychologists who counsel students, perform assessments, who help teachers, school administrators, and parents understand how children learn and develop are known as SCHOOL psychologists.
They are support students' ability to learn and teachers' ability to teach. They focus generally on mental health, learning, and behavior, to help children and youth succeed academically, socially, behaviorally, and emotionally.
When you remove a fuse from a switch and then take a resistance reading across the fuse using an Ohmmeter a good fuse will show zero or very minimal resistance.
<h3>
what is Ohmmeter?</h3>
- Electrical instruments that measure electrical resistance include ohmmeters.
- If a multimeter is set to measure resistance, it may also be used as an ohmmeter.
- The circuit or component whose resistance is to be measured receives current from an ohmmeter.
- Electrical resistance is measured using an ohmmeter and represented in ohms.
- The resistance to be measured can be connected to the instrument in parallel or in series using the simplest ohmmeters.
- It comes in three different varieties: series, shunt, and multi-range ohmmeters.
