    Lines LN1 and LN2 supply two different sections of the plant separated by a bus tie circuit breaker CB3, normally open. In case of failure of one of the two supply lines, ATS022 closes CB3; the available line thus powers both the sections downline. When the line is restored ATS022 restores the normal plant conditions by opening CB3.
