Abstract
774,274. Protective arrangements. STANDARD TELEPHONES & CABLES, Ltd. Jan. 19, 1953, No. 1480/53. Class 38 (4). [Also in Groups XXXVI and XL (b)] An interference suppressor comprises two capacitors of different values connected between an earthed point and two spaced points on a conductor. The capacitors resonate with their self-inductances and with the inductance of the conductor at two different frequencies, the result being an increase in the frequency range for which the transfer impedance of the suppressor circuit remains below a desired value. The figures show a symmetrical arrangement in which two pairs of capacitors C3, C4 and C7, C8 are connected respectively between bus-bars AB, CD and an earthed casing 13. Specification 712,650, [Group XXXVI], is referred to.
