Energy Metering Capabilities: The ADE7858ACPZ accurately measures and calculates active, reactive, and apparent power for precise energy metering. It supports single-phase and three-phase power systems, and has high-precision measurement capabilities. Power quality analysis function: The chip has powerful power quality analysis capabilities, which can measure and analyze power quality parameters such as harmonics, waveform distortion, voltage sags and swells, and frequency offsets in the power grid. This helps to monitor and evaluate the stability and quality of the power system.
