Detailed Solution
Download Solution PDFThe correct answer is option "3" i.e., 2 Current, 2 Voltage.
Explanation:
- In a three-phase power system, a Power Quality Analyzer (PQA) requires 2 Current and 2 Voltage probes for comprehensive monitoring.
- Each phase in the system necessitates a measurement of both current and voltage for an accurate assessment of power quality.
- The 2 Current probes are used to measure the current flowing through two of the three phases, while the 2 Voltage probes measure the voltage across those corresponding phases.
- This configuration allows the PQA to analyze key parameters such as voltage sags, swells, harmonics, and power factor, providing insights into the quality and stability of the electrical power supply.
- By utilizing 2 Current and 2 Voltage probes, the analyzer can capture essential data to diagnose and address potential issues in three-phase power systems, ensuring optimal performance and reliability.
