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 = 0.9 (capacitive)
and 0.8 (inductive). Depending on the type of system, which obviously comprises 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
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
® L 36 W,
not recommended, since the permissible current and power limits cannot be reliably maintained if
the permissible tolerances for the capacitors, control gear and lamps are fully utilized.
The limits for exploiting the permitted tolerances (close tolerance) for the capacitance of the series
capacitor (IEC 61049) and the impedance of the choke (IEC 60920) 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. Com-
pensation is not required if the lamps are operated with electronic control gear.
The following table shows the capacitance values for the various lamps.
