Energy Measurement

2)
Class index: active energy metering class 1.0; reactive: class 2.0
3)
Measurement function for:
- Import active energy
(Total and in each tariff)
- Export active energy
Punishment measurement
When meter is affected by external 0.5T high-intensity magnetic field interference, the current working
power will be calculated at rated voltage * 1.5 Imax
Instantaneous Values
The instantaneous values are:
- Voltage
- Current
- Power factor
- Active power
- Frequency
Demand Measurement
The demand for the period is simply the accumulated energy divided by the fraction of an hour that the
demand period is. When a demand period ends, the demand is compared with the channel’s active maxi-
mum demand (MD)register. If it is larger, the new maximum demand register and the time of maximum
demand is updated to the current time.
When the current max. demand is reset, the data of current max. demand will add to the accumulated
demand.
1)
MD measurement mode: 1,15,30 or 60 min(configurable)
2)
Manually clearing MD
- Manual billing: Pressing the Configuration button for over 5s.
- Programming billing: Billing by PC software and reset max. demand.
- Automatic Billing: Bill generated automatically on set billing date
- Tariff change: Bill generated automatically when tariff changes.
3)
Demand measurement content: Import active MD and duration (Total and in each tariff)
4)
Accumulate maximum demand measure content: Import active accumulated maximum demand
(Total and in each tariff)
