The Capacitors for “LIGHTINNG” applications, thanks to a very widechoice of models and construction options, offer the ideal solution to compensate fluorecent and discharge lamps. All fluorescent and discharge lamps need a reactor to switch and keep on the electric arc. This kind of load is very inductive (cos ø?0.5 lag) and it generates very high value of absorbed current. In order to decrease the absorbed current (optimizing the c.s.a. of the supply cables) and to improve the value of the cos ø; it is necessary to add a capacitor in the circuit. The national regulation of many countries impose the use of the compansation capacitors in lighting installations.
