Introduction of the product
DTS988 three-phase and four-wire carrier energy meter is anadvanced multi-functional meter, designed for three-phase powerusers and for meeting automation requirements of power network. Theproduct has adopted large-scale integrated circuits, as well as theapplication of digital sampling technology and SMT technology. Thedesign and manufacture keeps in line with electric power conditionof industrial users. The meter is featured with high accuracy,great utilization, high integration, stable capacity, friendlyoperation, and rich functions, considered as the first choice ofpower metering in such power management sites as residential areaof key power users , substations and power plants.
Functions
Power Measurement Function
It executes time-measuring of positive and negative(respectively active and reactive) energy, negative enery will beadded into positive energy .
Freeze function
Freeze and store automatically accumulative energy in each hour,at zero o’ clock, as well as at zero o’ clock on the monthlysettlement day.
Maximum demand measuring function
It measures maximum demand of active power, as well as theoccurring time.
Power parameters measuring
It can measure various power parameters such as split-phase andco-phase active power, reactive power, apparent power, powerfactor, voltage, current and frequency.
Multi-rate function
It has such rate definitions as 4 rates, 16 time consumption(including 8 current time consumption, and 8 time consumption forstandby), holidays and so on.
Events recording function
Record various events such as reverse energy, loss of voltage,over voltage, under voltage, loss of current, over current, undercurrent, phase failure, etc.
Programming function
All of the operations to meter (except timing), such as settingall parameters and functions, and clearing power demand, havehardware programming restrictions
Password management function
It has three-level passwordmanagement.
