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. For example, there have been cases of utility customers disabling power meters by attaching strong magnets or coils to the equipment which presents false measurement data to the controller.
Despite the popularity of optocouplers and transformers as isolation technologies, both of these solutions have tangible weaknesses that should be of concern for metering applications.
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.
