Portable Energy Meter Test System with Integrated Voltage and Current Source
Product name : Portable Energy Meter Test System with Integrated Voltage and Current Source
Item : PEC-A
Details :
Main Features:
·           Accuracy class: 0.05%
·           Measurement of errors for various induction and static energy meters (three phase three wire, three phase four wire, and single phase); Simultaneous measurement of errors for active and reactive  (true) energy meters in a loop; simultaneous measurement of errors of master and sub meter in a loop; proofreading of constant for various energy meters
·           Comparison measurement of voltage, current, power, power factor, phase and frequency of electrical instruments and transmitters
·           Measurement of transformation ratio for CT
·           Dynamic measurement and simultaneous display of three phase voltage, current, power, power factor, phase, frequency, and vector diagram etc.
·           Proofreading of constant by measuring pulse number, time, and value of power; dial measurement according to number of KWh, time and number of pulse; preset number of KWh, the dial will stop accordingly; automatic measurement for register
·           Measurement of harmonics of voltage and current (2nd ~51st ), measured data can be stored
·           Simultaneous measurement of three phase voltage and current, displayed in waves
·           Meter reading for multi function energy meter
·           Source integrated
·           GPS reference clock integrated, time pairing for energy meters
·           Any power factor and current outputs, fully measurement for measuring points
·           Detection of wiring failures for three phase wire circuit(48), three phase four wire circuit(96), four quadrant electrical measurement , displayed in hexagon diagram;
·           Data management:
-       Measured data can be stored and downloaded via a flash disk or RS232 communication port
-       Measured data of 1500 energy meters can be stored including operating parameters for further analysis
-       Communicable to PC, convenient connection to existing data base and management system; PEC Energy Meter Management System software is provided (optional)
-       Management software can be upgraded at anytime
·           Protection and alarm of voltage short circuit and current open circuit; faults and relevant phase sequence can be displayed and voice reminded
·           Measurement of electricity compensation
·           With high accuracy reference source enables self adjustment of voltage, current and Clamp-on CT’s, long term accuracy assured
