1. Overview
PD typeDigital display meterIt is an ideal device for power quality monitoring. This instrument has the function of simultaneously measuring current, voltage, frequency, active power, reactive power, apparent power, electrical energy, power factor, etc. in the power grid. Suitable for distributed detection of transformers, generator sets, capacitor banks, and motors, as well as on-site monitoring and display of power grids and automation control systems.

2. Function Introduction
◆ Phase voltage: Ua, Ub, Uc (three-phase four wire)
◆ Line voltage: Uab, Ucb (three-phase three wire)
Current: Ia, Ib, Ic
Active power: Pa, Pb, Pc, Psum (active phase power and total power)
◆ Reactive power: Qa, Qb, Qc, Qsum (reactive phase power and total power)
◆ Apparent power: Sa, Sb, Sc, S (apparent phase power and total power)
Power factor: Pfa, Pfb, Pfc, Pf (phase separation and average power factor)
◆ Frequency: F
