1.1 Summarization
DTSD/DSSD718(719/720) Three-phase Four-Wire/Three-phase Three-wire Electronic Energy Meter is developed by Shenzhen Clou Electronics Co., Ltd. as the New Generation of Intelligent hi-tech energy metering product. Based on our own advanced patent technology, this model is designed complied to the standards of IEC1036-1996, DL/T614-1997, DL/T645-1997. Combining with the measurement, monitoring, alerting, display and communication functions, it can measure the total export &import active energy,total export &import reactive energy,time-spare energy, total four quadrant reactive energy and time-spare energy; able to measure the total M.D. of export &import active、export& import reactive、four quadrant reactive and the date and time of max. demand occurred ; able to measure the phase voltage, current, phase angle, power factor, active power, reactive factor, apparent power and three phase total active power, total reactive power, total apparent power, power factor and frequency, 1st ~31st harmonious; detect and record events like the loss voltage, loss current; realize the Remote Meter Reading; and the expanded function is available as well. The model is ideal product applied in the electric power plants,substations and metering system.
