Technical details and manufacturing context for Power Monitoring Device

Definition
A power monitoring device is an electronic instrument designed to continuously measure, analyze, and record various electrical parameters in AC or DC power systems. It provides real-time data on voltage, current, power, energy consumption, power factor, harmonics, and other electrical characteristics to enable energy management, equipment protection, and system optimization.
Working Principle
The device operates by using current transformers (CTs) and potential transformers (PTs) to safely sample high-voltage/high-current signals. These analog signals are converted to digital data through analog-to-digital converters (ADCs). A microprocessor then processes this data using mathematical algorithms to calculate electrical parameters. Results are displayed locally, transmitted via communication protocols, or stored in internal memory for analysis.
