PEC-9 Three Phase Watt-hour Metter Check Device

详情

High brightness, high definition, high resolution liquid crystal display (**0***0 touch screen); The system utilizes high-speed, high-accuracy digital multiplier to test all parameters such as active and reactive power, voltage, current, frequency, phase etc and calibrates them through software; Assure the power accuracy (0.1% or 0.*5%) between the temperature of **0℃ to **0℃; Test electric energy in four quadrants; Equipped with ±0.2 %5A transformer (including split non-repeat errors, touching errors, outside magnetic field interference errors, angle errors and so on); Able to test the 2nd ~*1st harmonic wave of three-phase voltage and current, and save all harmonic wave’s data; Able to show three waveforms of voltage and current simultaneously; Provide error calibrating function, so that it is convenient to calibrate errors, but it needs password; Unique “no dirt inside” structure design; heat elimination & ventilation district and inner box are separated, so that the inside is able to be kept clear permanent and make sure stable operation of device;
