摘要

the decision to retain half u043fu043eu0437u0432u043eu043bu00a0u0435u0442 substation in the case of cz on u043fu0435u0440u0435u043cu044bu0447u043a e between a switch and a current transformers 3 and 4.this u043eu0431u0435u0441u043fu0435u0447u0438u0432u0430u0435u0442u0441u00a0 due to the fact that the device has a block of logic and the third and fourth differential relays 9 and 10, each of which is inserted between the u0434u0438u0444u0444u0435u0440u0435u043du0446 u0438u0430u043bu044cu043du043e the current transformers 1 and 5, 2 and b power transformer and power line and the first and second differential relays. 1, z. s - lu, 1).
