with reference to the high pressure sodium constant wattage auto transformers, how does the ignitor work? Does it stop and start the supply to make the reactor section produce high voltages to strike the sodium?if so why does inductive reactance not oppose the rapid change in voltage?
Also which coil limits the current once the lamp is illuminated?
And finally what kind of voltage are we looking at on the link between the auto and reactor coils?

also to agree with the guys in this section (on another topic)your doing a great job i to have learned a lot more since using the forum and enjoy being able to ask others with more experience and knowledge cheers mate [Linked Image]
