What type of electric service meter is designated as PMYD 222-7756?

The designation PMYD 222-7756 points to a polyphase, maximum demand electric service meter. This type of meter is specifically designed to measure power consumption in multi-phase systems, which are common in industrial and commercial applications where high demand is typical. The "P" in PMYD indicates that it is polyphase, meaning it can handle and measure multiple phases of electricity simultaneously. The "MYD" portion refers to maximum demand, which indicates that this meter not only tracks the total consumption of electricity but also records the highest level of demand over a specified period. Understanding this function is crucial for facilities that need to monitor their electricity usage closely to manage costs and demand charges effectively.
