Although smart meters are more sophisticated than electromechanical power meters, a primary concern in smart meter design is the integrity of measurement data, which can directly impact a utility provider’s billing revenue. With the worldwide build-out of the smart grid, meters are increasingly installed in an electromagnetically noisy locations. Certain isolation techniques are potentially susceptible to exploitation. Despite the popularity of optocouplers and transformers as isolation technologies, both of these solutions have tangible weaknesses. Find out how modern CMOS digital isolators provide accurate, uncorrupted power measurement data across an isolation barrier to address these concerns in smart meter applications.
