The electronic ballast principle is as shown in figure 1, the indexes that affect the electronic ballast's performance are: the preheat tube voltage of the start-up stage, the preheating filament current and preheating time, the stabilized lamp voltage, the lamp current, the oscillation frequency, the input current, the input power and the power factor, so we need to install the sensor to collector the lamp voltage of the output port, the filament current, the cathode circuit and the oscillation frequency, the power, current, power factor of the input port.etc.
