DEVICE FOR TRANSMITTING DATA SIGNALS OVER OVERHEAD THREE-PHASE POWER TRANSMISSION LINE Russian patent published in 1998 - IPC

Abstract RU 2111610 C1

FIELD: electrical engineering; telemechanics systems where power transmission line is used as communication channel without using high-frequency traps. SUBSTANCE: power transmission lines rated 0.38, 10, 35 kV are used for the purpose. Device has four air-core inductance coils 1-3, 14, eight resistors 11,19,21,23-25, 33,56, six capacitors 10, 15-18,34, eleven diodes 4-9, 26,28,32,35, four thyristors 12, 29-31, data source 13, DC voltage supply 20, and switch 22. EFFECT: improved reliability under overcurrent conditions and provision for automatic recovery of device serviceability. 1 dwg
