Technical Guide
3.2.2 Compensation
The need to compensate for the reactive power depends on the technical connection
conditions of the electricity supply company. Compensation for reactive power is
covered by the EN 61000-3-2 standard (see 9.1.2). Compensation can be provided on
an individual basis per luminaire, for groups of luminaires or at a central location.
Generally, electricity consumption should involve a power factor of between Cos
(capacitive) and 0,8 (inductive). Depending on the type of system, which obviously com-
prises more inductive loads than just low-voltage discharge lamps, one has to decide
which type of compensation should be used:
• Individual compensation per luminaire
• Group compensation
• or central compensation.
The capacitor must be connected in parallel with the mains terminals. Compensation
with a series capacitor is possible in certain circumstances but, except in the case of
OSRAM DULUX
power limits cannot be reliably maintained if the permissible tolerances for the capaci-
tors, control gear and lamps are fully utilised.
The limits for exploiting the permitted tolerances (close tolerance) for the capacitance
of the series capacitor (± 2 %) and the impedance of the choke (± 1,5 %) or lamps
cannot be reliably met.
Mains parallel capacitors are not permitted in existing audio-frequency remote control
systems operating at high frequency. They are suitable only for compensation with
series capacitors.
Compensation is not required if the lamps are operated with electronic control gear.
The following table shows the capacitance values for the various lamps.

24-26 W CCG for CFLs (2,7 F for 18 W CCG for fluorescent lamp).
For Cos phi = 0,95; Dielectric strength of the capacitors 250 V ac; Capacitance tolerance ±10%
For Cos phi = at least 0,95; Dielectric strength of the capacitors 450 V ac
To guarantee the prescribed operating and preheating values,
capacitors and control gear with narrow tolerances (± 2 %
and ± 1,5 % respectively) are needed for series compensation.
