Abstract
In capacitor equipment which includes a series-connection, connected to an alternating voltage network, of two anti-parallel connected thyristors, one capacitor and one reactor, a control device is connected to the control electrode of the thyristors and arranged to ignite the thyristors alternately at times in the vicinity of the peak value of the alternating voltage. A sensing member is provided for sensing an operating magnitude in the series connection and a level-sensing member is connected to the sensing member and to the control device. The level-sensing member influences the control device to produce ignition of both thyristors of the instantaneous value of the operating magnitude falls outside a pre-determined interval.
