DDSF 798 Single Phase Tariff Electronic energy Meter can measure active energy and reactive energy, and can work respectively in eight time segments and four tariffs. At working time it can give the maximum demand of energy, and is excellent against fraud function. Historic data can be stored and infrared communication is provided. The meter can measure at sequential and reverse way. It provides pulses output for measuring and being one part of large-scale auto meters reading system.
The meter acords with IEC 62053-21, 62053-23. Electromagnetism capacitability meets IEC 62052-11. Meter reading and data transferring controlled by tariff and load are the range within IEC 61107-1996.
