PZ Series electric energy meters, adopting AC sampling technology, can measure many single phase or three phase grid electrical parameters such as current, voltage, power, electric energy etc. directly or indirectly. It can be used for local display, and also can be connected with the control equipment to form measuring and controlling system.
