operation
Lead-lag circuit
Series circuits (tandem circuits) are possible only for certain types of lamp in which the
arc voltage does not exceed certain values (see 3.2.1).

1)
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 data for the capacitor see 3.2.2.
In accordance with IEC 60901, measurements are taken at 220 V/50 Hz on the reference control gear.
There is no change, however, in the electrical lamp data for 230 V and 240 V supplies, provided
suitable control gear is used.
