| Subject - Series to parallel circuit adaption? | |
| hoangtd2bk |
I am Vu Hoang I work in an airfield lighting maintenance team in an airport. Airfield lighting uses series circuits to feed the runway and taxiway lighting, the current in the circuits could step from 2.8A to 6.6A depending on lamp illumination level. A Constant current regulator (CCR) supplies the electrical energy to the series circuits and maintains the output current to nominal setting over a wide range of input voltage and load conditions. Lamps connect series through a series-to-series isolation transformer. In our system, we used 100W isolation transformer and 100W/6.6A lamps are connected to the secondary terminals of transformers. But now we want to add some 220V/50W flourescent lamps to this serial circuit while flourescent lamps use parallel curcuit. What should i do? Please give me some advice, it would be appreciated!

| JimmyDee | The runway lighting that I,ve worked on worked off from current transformers for the individual lights. Each light had lights own current transformer to power the light. These CTs were powered by being installed around a shorted continuous loop that was current regulated by remote control. To add anything to that loop would probably need to be engineered by someone in the FAA or equivalent. Jim |
| wareagle | You can not add the fluorescent lamps to this circuit. The series circuit maintains a constant current to the lamps in the circuit by lowering or raising the voltage. You will have to find another circuit to connect to the fluorescent lamps. |
