DSSD / DTSD 798 Three Phase Multifunction Electronic Energy Meter is interlationally digitalized with SMT advanced process, designed and manufactured for industrial field. It is of low consumption, long service life and highly reliable, and it mainly measure active energy and reactive energy power of alternative current of three phases. The meter also can measure and give various electricity parameters of AC. And it can be woken up by touching or non-touching after power cut.

The meter accords with requirements mentioned in national standards of GB/T 17215-1998 Alternatve current static watt-hour meters for active energy (Class 2 and 3), GB/T 1783-1999 Alternative current static watt-hour meters for active energy (Classes 0.2 and 0.5), IEC60687, IEC61036-2000 and IEC61266-1995, The communication accords with DL/T645-1997 Multifunction Energy Meter Communication Protocol.
