Power-Quality Monitoring (Part 2): Designing a Standards-Compliant Meter (Download)

The basic components of an instrument designed for power-quality measurement are shown in Figure 1. First, the current and voltage transducers must account for the operational range of the instrument and adapt the input signal to the dynamics of the analog-to-digital converter (ADC) input. Traditional transducers are the first source of uncertainty in the measurement. Therefore, correct selection is of great importance.
