Power Meter, is for power monitoring and energy management needs power system, industrial and mining enterprises, public facilities, intelligent large public buildings and design. It all commonly used high-precision measurement of electrical parameters, such as three-phase voltage, phase current, active power, reactive power, frequency, power factor, four-quadrant power, etc, to the use of high visibility LCD display instrument measurement parameters and power system operation information. Power meter function, model range, price is not the same, energy metering programs are also varied, therefore, should be a reasonable option, achieve better value for money. According to the Ministry of Housing and Urban document 114 large public building energy consumption data for the implementation of classification, sub-metering of electricity by the power of electricity, lighting and electrical sockets, air-conditioning and electricity sub-metering conduct special power management. So where there is distribution box for dormitories, shops, wards, etc. should be metered into the local distribution box Inquiry economic accounting unit, can be used DDS1352 or DDSF1352 meter; according to the Ministry of Housing and Urban Hebei document distribution box number 114, to large public building energy consumption data of category, sub-metering distribution box much money, of power according to the power of electricity, lighting and electrical sockets, air-conditioning and electricity sub-metering conduct special power management. Therefore, for dormitories, shops, wards, etc. should be metered into the local economic accounting unit, can be used DDS1352 or DDSF1352 meter; distribution box much money, but abundant proof (online consultation), Hebei distribution box by Zhejiang Koretoyo proof Electric Co.
