summary:

The digital intelligent single-phase meter is used for measuring and displaying electrical parameters such as current, voltage, frequency, active power, reactive power, and power factors in power grids and automation systems. By setting the magnification on the panel, it intuitively displays the operating point parameters of the primary side of the system. It has the advantages of high accuracy, good stability, and anti vibration, and can directly replace the original pointer instruments.
