What percentage of service capacity should an electric meter accurately measure?

An electric meter is designed to provide accurate measurements across a wide range of service capacities to ensure reliability in billing and efficiency evaluations. A meter that measures from 5% to 100% of service capacity allows for both low-level usage and maximum capacity use to be monitored effectively. This range ensures that even at minimal load conditions, the meter can accurately register consumption, which is essential for both residential and commercial customers.

Measuring from very low levels up to full capacity enables utility providers to gain a comprehensive understanding of energy usage patterns and ensures that meters remain effective across changing load conditions. This broad range is crucial for the meter's functionality and aligns with industry standards for measurement accuracy, making this the most appropriate choice.
