Product Detailed

Three phase power meter/energy meter
high precision
high reliability
high capability of over loading
low power consumption


According with each technical requirement for calss-1 and class-2 immobile active power energy watt-hour meter(three phase Power meter/energy meter) stated in the GB/T17215-2002 (IEC 61036-2000) standard, DSSD3338 Three-Phase Three-Line/Four-Line Electronic & Active Power Energy Watt-Hour Meter is used to count the three-phase active power energy of Alternating Current with rating frequency of 50Hz/60Hz.

The voltage value and current value on the three phases being measured are changed to appropriate voltage signals, and these signals enter into the special integrate circuit of the three-phase watt-hour meter in which the A/D conversion and multiplying data will be finished after pretreatment, then output pulse signals proportioned with the power measured, and then output the watt-hour test pulse and the driving pulse of the electromagnetic counter after the frequency demultiplication by the frequency divider, achieving the three-phase watt-hour measurement. The width of the motion pulse is 80ms±5ms. 

Functions and characteristics of the three power meter:

1. High performance: wide range of measure, good linearity, both positive and negative active power energy watt-hour measurement, output of the pulse of watt-hour test and remote test, east to connect with computers, remote-controlled reading meter and processing data.

2. High reliability: supplied by three phases power supply that the measuring accuracy would not be impacted even if one or two phases power is removed; the meters reliability is ensured due to the high quality components and advanced SMT processing technology used in the system.    

3. High capability of over loading: the meters capability of over loading is rather improved, for the current mutual inductor is used as the current-sampling component.   

       4. Long life-span: the characteristics such as Long life-span, reliable performance, high precision and none mechanical abrasion owned by the electronic components are well performed, for the full-electronic measuring machine is adopted, extending the life-span to more than 10 years during which checking and adjustment is not needed for the few augment of the error.
