Questions & Step-by-Step Solutions
What is the function of a transformer tap changer?
Step 1: Understand what a transformer is. A transformer is a device that changes the voltage of electricity.
Step 2: Learn about the turns ratio. The turns ratio is the number of coils (turns) of wire on the primary side compared to the secondary side of the transformer.
Step 3: Know that voltage can change based on how much electricity is being used (load conditions).
Step 4: A tap changer is a mechanism on the transformer that allows you to change the number of turns on the primary or secondary side.
Step 5: By adjusting the turns ratio using the tap changer, you can control and regulate the output voltage of the transformer.
Step 6: This helps maintain a stable voltage even when the amount of electricity being used changes.
