1. The function of a potential transformer or PT is to step down high voltage to a lower voltage that can be safely measured by instruments or meters.
2. The transformer that uses a single winding to produce voltage transformation is an autotransformer.
3. The function of autotransformers used with the starters of large AC motors is to provide variable voltage starting and control of the motor.
4. Power transformers are rated in kilovolt-amperes (kVA) or megavolt-amperes (MVA).
5. Transformers are used onboard ships with alternators to step up the voltage for efficient power transmission over long distances.
6. The secondary of a current transformer is never left open-circuited because it can lead to dangerously high voltages that can damage the transformer and connected equipment.
7. The primary current in a current transformer is governed by the current in the circuit being monitored or measured.
8. While using a current transformer, it is essential to maintain at all times a closed circuit on the secondary side in order to prevent damage to the transformer and also to ensure accurate measurement of the current.
9. A transformer is commonly used for distribution purposes to step down the high voltage from the power station to a lower voltage suitable for distribution to homes and businesses.
10. A step-down transformer is generally used in a starter to reduce the voltage and control the starting current for the motor.
