ABSTRACT:
The invention concerns a monitoring circuit for a number of simultaneously current-carrying valves. In order to obtain an alarm signal in the event of trouble in a valve, provision is made that the primary winding of a current transformer is arranged in series with each of the valves; that the secondary windings of the current transformers are connected in a ring via intermediate taps; and that each intermediate tap is connected to a center tap of a bridge circuit constructed from auxiliary valves, whose output current can be taken off as the alarm signal.
