What is the function of an oscilloscope in a 3-phase system?

The function of an oscilloscope in a 3-phase system is to visualize the waveform of voltage or current signals. This tool allows engineers and technicians to observe the actual shape of electrical signals over time, providing valuable insight into the performance of the 3-phase system. By examining these waveforms, users can identify issues such as distortion, phase relationships, and anomalies that may affect system efficiency and operation.

Oscilloscopes can display multiple waveforms simultaneously, making them particularly useful for analyzing the interactions between the three phases in a system. This capability enables users to determine if the phases are balanced and functioning properly, which is crucial for maintaining the reliability and efficiency of 3-phase electrical systems. The detailed visualization provided by the oscilloscope allows for more informed troubleshooting and diagnostic actions compared to other measurement tools that might only provide numerical values or single-phase analysis.
