maximum demand meter
A maximum demand meter is a sophisticated electrical measurement device that records the highest amount of power consumed over a specified time interval, typically 15, 30, or 60 minutes. Unlike traditional energy meters that only measure total consumption, these specialized instruments monitor and store peak power usage patterns, making them invaluable for both utility companies and large-scale energy consumers. The device operates by continuously measuring electrical parameters such as current and voltage, calculating the average demand over the predetermined interval, and retaining the highest recorded value until manually reset. Modern maximum demand meters incorporate digital technology, featuring LCD displays, data logging capabilities, and communication interfaces for remote monitoring. These meters are essential in industrial and commercial settings where power consumption management is crucial for cost control and infrastructure planning. They help facilities avoid penalty charges from utilities for exceeding agreed-upon demand limits and assist in optimizing power usage patterns. The technology employed in these meters includes advanced microprocessors, precise measurement circuits, and robust memory systems to ensure accurate and reliable demand recording. Many contemporary models also feature multiple tariff capabilities, load profiling, and power quality analysis functions, making them comprehensive power monitoring solutions.
