Application:
PD76-24E-WFF Digital indicating Panel Mounted Electrical Measuring Instrument is designed for the electrical monitoring for utilities, industrial mining corporations, intelligence towers and communities. It adopts large scale IC, digital sampling technology and SMT technology. It can measure all the common electrical parameters with high accuracy, such as three-phase voltage, three-phase current, active power, reactive power, frequency, power factor, active energy, reactive energy and four quadrant energy. It is capable of multi-tariff function (10 time segments,4 rates).
