Technical details and manufacturing context for Measurement Module

Definition
The Measurement Module is a critical sub-assembly of an Industrial Power Distribution Test Bench. Its primary role is to provide precise, real-time data acquisition for electrical characteristics such as voltage, current, power (active, reactive, apparent), power factor, frequency, and harmonic distortion. It interfaces with sensors and transducers, conditions the signals, and converts them into digital data for analysis, display, and logging by the test bench's control system, enabling performance validation, efficiency testing, and fault diagnosis of power distribution equipment.
Working Principle
The module operates by receiving low-level analog signals (e.g., mV, mA) from current transformers (CTs), potential transformers (PTs), or other sensors connected to the test circuit. These signals are passed through signal conditioning circuits (amplification, filtering, isolation) to ensure accuracy and safety. An Analog-to-Digital Converter (ADC) then digitizes the conditioned signals. A microcontroller or Digital Signal Processor (DSP) processes this digital data, applying calibration factors and performing calculations (like RMS, power computations) to derive the final measurement values, which are then communicated via standard protocols (e.g., Modbus, Ethernet) to the main controller.
