Abstract

1,029,720. Protective arrangements. SIEMENS & HALSKE A.G. June 4, 1964, No. 23091/64. Addition to 949,627. Heading H2K. The protective arrangement of the parent Specification is modified so that the pulses produced at each end of the protected line are derived from either of two A.C. reference voltages dependent on different components of the currents at that end. In the arrangement disclosed, certain items of the arrangement of the parent Specification are duplicated and various relays are provided so that the arrangement may compare the phase relationship between pulses produced by voltages dependent on the negative phase-sequence current components at each end or the zero phase-sequence current components at each end.
