What does Kh represent on an electric meter badge?

Kh represents the watthour or rotor constant on an electric meter badge. This constant is critical for understanding how the electric meter measures energy consumption. Essentially, Kh provides an indication of how many watthours are represented by one revolution of the meter's rotor. For instance, if a meter has a Kh value of 7.2, it means that for every complete turn of the rotor, the meter registers 7.2 watthours of energy usage.

This measurement is vital for ensuring accurate billing and energy usage tracking. The value of Kh can vary between different types of meters, depending on their design and intended use, which makes it an important specification for technicians and utility providers when assessing the functionality and accuracy of an electric meter.
