Company Info

 

Please contact us by our website rowwin.com Portable Three Phase Energy Meter Test Instrument Product Features: 1. Show on high-brightness, high-definition, high resolution ratio 5.7＂ (320*240) TFT color liquid crystal display; 2. The system utilizes high-speed, high-accuracy digital multiplier to measure all parameters such as active (reactive) power, voltage, current, frequency, phase etc and calibrates them through software; 3. This device has no potentiometer, which protects it from error change caused by transportation or other factors, and increases stability and reliability of the system greatly; 4. The self-calibrate function of transformer is able to assure its worst case accuracy stability. When used 5A or 1A split core current transformer, the current reaches 1mA,it is able to check the line connection under the situation that there are PT, CT but they are unloaded; 5. Self-test between phases guarantees the accuracy stability of this device all the time; 6. The system adopts the digital absolutely reactive testing technology that is first invented in our country. This technology makes testing under reactive come true, not influenced by voltage and current unbalance, phase angle dissymmetry and frequency change. This technology also increases the reactive accuracy rate up to 0.1% the first time in our country. 7. Assure the electric energy accuracy (0.1% or 0.05%) between the temperature of -20℃ to +40℃; 8. Equipped with
