Title: DC fault location in cable from central transmission station - has constant current supply producing voltage across cores compared with voltage from count stage
Inventor: BLOEMKER UWE
IPC: H04B17/40
Filed: 1978-12-13
Abstract: The direct current fault location circuit is for a transmission line with intermediate stations supplied from a central transmission station. Each intermediate station has transmission line sections with alarm contacts in lengths of line of standardised resistance measured from the transmission station. The alarm contact produces a short circuit when the effective level of the signal is below a given value. This restricts the direct current loop resistance measured from the central control station to a given value. The locating volt. prod. by the constant supply of current through the cores in the cable are compared with the ref. volt. which is derived from the position of a counter. The counter has an equal number of output stages as there are possible fault sections. The counter is controlled by a pulse generator which operates when the locating volt. differs from the ref. volt.
