N2 - Under light loading conditions, reactors provide an option for keeping voltages below steady state limits. In this paper, the impact of the number of operations of a circuit breaker on the choice of reactor technology (i.e. fixed versus magnetically controlled) is studied. In particular, the impact of circuit-breaker maintenance cost on the life-cycle cost of a reactor installation is evaluated. The study shows that when the expected number of circuit-breaker operations is high, it is beneficial to consider the use of a magnetically controlled reactor as this leads to very few operations. In addition, the savings in circuit-breaker maintenance cost can justify the extra cost of a magnetically controlled reactor over its life cycle. The economic life-cycle cost assessment can help to identify the lowest cost solution over the project life cycle.
