ABSTRACT:
Using a switching circuit (2) for a reactive power compensation device (1), he compensation capacitors of the reactive power compensation device (1) can be switched on with voltage measuring devices (30, 31) which are switched between two phase conductors (3, 4) if the the voltage is the same on both sides of an open phase conductor switch (24). In a preferred embodiment, closing the second phase conductor switch (25) occurs triggered by a delay device (36) following a fixed delay time. In another preferred embodiment, switching on occurs when the voltage is the same between the phase conductors (4,5) on both sides of the second phase conductor switch (25), whereas this condition can be checked with two other voltage measuring devices switched between the phase conductors (4, 5) as well as with another equivalence comparator.
