In January 2015, Henan Compere Intelligent Technology Co., Ltd. established a cooperative relationship with Beijing Capital International Airport. Compere Intelligent provides the KPM73 multi-function meter for the power quality monitoring instrument of its power distribution system. This meter is mainly used to monitor and measure the power parameters in the power distribution system; collect the energy consumption data required for the cost center analysis; limit monitoring alarm; power quality analysis; green building, etc., KPM 73 multi-function meter can monitor more than 30 Basic power, measurement shows the average power factor in the past three months, accurately grasp the monthly reactive energy consumption of the enterprise, and can support up to 51 harmonic calculation, total harmonic distortion rate calculation, unbalance rate, current K coefficient calculation, etc. It has a voltage and current sampling of 256 points/cycle, which can ensure the measurement accuracy of the instrument. KPM73 multi-function power meter can effectively help the Capital International Airport achieve centralized monitoring and management, reduce human error and record inaccuracy, and improve power safety and intelligence.
