Measurement of High AC Voltages
Methods/techniques used for the measurement of high AC voltages include:
1. Potential dividers: A potential divider is a resistive voltage divider used to measure high voltages. It consists of a series of resistors that are connected in series, with the voltage to be measured applied across the entire series.
2. Potential transformers: A potential transformer is a type of instrument transformer that is used to step down the high voltage to a lower, more manageable level. It is commonly used in power systems for metering and protection purposes.
3. Electrostatic voltmeters: An electrostatic voltmeter is a type of voltmeter that measures voltage by measuring the electrostatic force between two conductive plates. It is commonly used in high voltage laboratories for accurate voltage measurements.
4. Half-effect generators: A Hall-effect generator is a type of sensor that measures magnetic fields. It can be used to measure high voltages indirectly by measuring the magnetic field generated by the high voltage.
Exception: Half Effect Generators
The correct answer is option D, i.e., Half-effect generators because they are used to measure magnetic fields and not high voltages directly. They are not suitable for measuring high voltages as they do not provide accurate measurements of the voltage. Therefore, they cannot be used as a method/technique for the measurement of high AC voltages.
