Three-phase smart energy meters produced
byDongfang Wisdom Electric
Co.,Ltdis
designed and manufactured on the basis of switching power supply
technology, and has adopted the advanced large-scale integrated
circuits technology, experienced software algorithms, low power
consumption design and SMT process according to the requirements
ofinternationalstandards. The product is characterized by
integrated functions of metering, display, communication,
detection, etc.It
provides with functions of metering the import and export active
power of three phases, the reactive energy of four quadrants and
demand by time period accurately; metering voltage, current, active
and reactive power, power factors, etc. of three phases; detecting
and recording loss of voltage, loss of current, loss of phase, etc;
performing the function of remote and local meter reading,
programming, etc. It is widely used in grid gateway, power plants,
substations, comprehensive energy measurement and management of
enterprises and institutions and TOU metering for industry
users.
