1.Total 4 quadrant kVAh, kWh and kVArh billing period and total accumulated
Max demand, predicted demand
3.Energy today, yesterday, this week, last week, thus month, last month etc
ToU peak, std off peak and Max demand
V,I,pf total and per phase
6.V,I THD and marmionics, symmetrical components.
9.Historical logs (1 week to 2 years depending on memory)
Many meters and their registers may be accessed via modbus for real-time data trending but more complex software is required to retrieve the historical data.
