Three Phase Energy Meter Portable Test Equipment(W

Three Phase Energy Meter Portable Test Equipment(With Voltage source and Current Source) 1. Brief Introduction: KP-P3001-C three-phase portable test equipment with current and voltage source is an ideal device to test all kind three-phase energy meters accuracy below 0.2, especially for testing un-installed meters on site. The equipment can generate 3-phase voltage, 3-phase current and any power factor signal, the standard meter inside the equipment is class 0.05. The equipment is box structure, light, and easy to carry, it is very convenience to test meters on site, moreover the equipment can be used for repair meter in meter manufacture and as testing equipment in R&D institute. 2. Advantages: d. Displays of vector diagram for analysis of the supply conditions. e. DDS technology signal generator: The signal generator adopts digital sine wave composing technology. The signal generator can trace the voltage phase and supply a dummy load to the tested meter by outputting adjustable current with different phase ; f. High efficiency D-Class current amplifier and voltage amplifier: The equipment adopts PWM power amplifier(or we called D-Class amplifier), which is high efficiency (>85%) and very low heat consumption. The amplifier has protect function ,it can avoid damage due to wrong connection or other manual operations. Current amplifier and output shifter can output different current; Voltage amplifier can output different voltage; g. Large LCD screen display. 3.
