FAQs

1. What is CT and PT in electrical systems?

CT (Current Transformer) and PT (Potential Transformer) are instrument transformers used in electrical systems to measure high current and high voltage safely. CT measures current while PT measures voltage in power transmission and distribution applications.

2. What is the purpose of Power Measurement using CT & PT trainer?

The trainer is designed to help students understand the practical concepts of power measurement, voltage sensing, current sensing, and the working principles of CT and PT in electrical engineering experiments.

3. How does a Current Transformer (CT) work?

A Current Transformer reduces high AC current to a lower measurable value so that standard measuring instruments like ammeters can safely measure current in electrical circuits.

4. Why is a Potential Transformer (PT) used in electrical measurements?

A Potential Transformer is used to step down high AC voltage to a lower value suitable for voltmeters, protective relays, and monitoring instruments for safe and accurate measurements.

5. What experiments can be performed using the CT & PT trainer?

Students can perform experiments related to measurement of AC current, AC voltage, power, wattage, power factor, turns ratio analysis, and practical applications of CT and PT in electrical systems.
