DEVELOPMENT OF FACILITY COMPLEX FOR SELECTIVE SIGNALLING OF ONE-PHASE EARTH IN CABLE NETWORKS 6 - 10 kV

The work covers the electromagnetic transients at one-phase earths in the cable networks 6 - 10 kV and also the signalling devices of one-phase earths. The analytical solutions for equations of the transients at one-phase earths in the compensated and non-compensated cable networks and also the principles for construction of the signalling and registaration devices of one-phase earths have been proposed. The device complex ("TEMP-1", "Impuls", signalling and registration devices of one-phase earths) possessing the more high technical improvement in comparison with the actual devices of analogous purpose has been developed. More than 80 device sets "TEMP-1" and "Impuls" have been introduced in the electric cable networks 6 - 10 kV of Ivenergo, Kostromaenergo, Vladimirenergo, Bashkirenergo a.o. The electric power supply reliability and operation comfortability have been increased.
