Abstract

A device for cold filament testing signal lamps (L) which are located in the exterior system of a signal box and are fed via lamp transformers (LT). For the purpose of testing, the inductive resistor of the primary winding of the lamp transformer is evaluated. The primary winding is connected for this purpose in a measuring circuit which extends from a measurement voltage source (QM) via the cable conductors used for feeding lamps, and contains an inductive measuring resistor (W). The current flowing in the measuring resistor or the voltage dropping across the measuring resistor is evaluated by comparison with the corresponding measurement variable occurring when the measuring resistor is fed directly with the measurement voltage. <IMAGE>
