What is the power factor of the double power HPS lamp ballast? Why is the high voltage sodium lamp ballast teacher easy to burn? Do you know what the trouble is?Explain.
General is to look at the electronic ballast or ballast, even determine the electronic inductor, still depends on the manufacturer, general electronic ballast power factor in about 0.98, ranging from 0.6---0.8 low inductance ballast.
High pressure sodium lamp is a kind of high intensity gas discharge bulb. Due to the negative resistance characteristics of gas discharge lamp, if the bulb alone received the power grid, the working state is unstable, with the discharge process continues, it will lead to the current in the circuit infinite rise, until the last lamp or circuit parts are overcurrent burned.
General is to look at the electronic ballast or ballast, even determine the electronic inductor, still depends on the manufacturer, general electronic ballast power factor in about 0.98, ranging from 0.6---0.8 low inductance ballast.
