Chapter 1. Brief Introduction YD2000 series intelligentized power meter and intelligentized measure & control power instrument (shorted as YD2000 series) is a kind of integrated intelligentized 3-phase measuring meter for power parameters, which have the functions such as programmable function, automated measuring, LCD (YD2000, YD2100, YD2020)/LED (YD2030, YD3000) displaying, power accumulating, real time clock (YD2000&YD2100), intelligence analyzing, max or min remembering (YD2000, YD2100), digital communication and so on. They integrate digitalization, intelligentization and network. So they can realize measure and analysis automatically and reduces man-made mistakes when they replace power transducers, electricity meters, digit displaying meters, digit collecting meters, and recording &analyzing meters fully. There are perfect products made up of electric automatic system. There are the revolutionary designs compared to traditional meters, whose makeups are close, whose circuits are advanced, and whose measuring functions are strong. YD2000 series can be applied in fields of electric power, telecom, oil, colliery, metal, railway, city planning, and intelligent building. Chapter 2.
