Phasemeter

A phasemeter, also known as a phase meter or phase angle meter, is a device used to measure the phase difference between two electrical signals. It is commonly used in various fields such as electronics, telecommunications, and power systems.

Phasemeters are typically used to measure the phase angle between a reference signal and a test signal. The reference signal is usually a known standard signal, while the test signal is the signal being measured. By comparing the phase angles of these two signals, the phasemeter can provide information about the phase difference between them.

Phasemeters can be analog or digital, depending on the type of measurement and the level of accuracy required. Analog phasemeters typically use a needle or a dial to indicate the phase angle, while digital phasemeters provide numerical values on a display.

Phasemeters are commonly used in applications such as power system synchronization, audio signal processing, and frequency analysis. They are essential tools for engineers, technicians, and researchers working with electrical signals and systems.
