2.2.3 Inductive operation Series circuit
Series circuits (tandem circuits) are possible only for certain types of lamps in which the arc voltage
does not exceed certain values (see 3.2.1 Permissible lamp/CCG combinations and system data,
p. 47).
Measurement conditions according to IEC 60901:
220 V / 50 Hz supply voltage1)
Operation on reference gear
Ambient temperature 25°C
Lamps aged 100 hours

1) In accordance with IEC 60901, measurements are taken at 220 V/50 Hz on the reference control gear. However, there is no change in the
electrical lamp data for 230 V and 240 V supplies, provided suitable control gear is used.
2.2.4 Inductive operation Lead-lag circuit
With certain lamps in two-lamp inductive arrangements, a lead-lag circuit can be set up in which
one of the two CCGs is combined with a series capacitor. For the capacitor data see 3.2.2
Compensation.
