In power system switching transients occur during normal switching. Not only
they depend on the system parameters, but also time affects the evolving inrush
transients. For this reason switching operations performed with appropriate timing can
minimize the harmful effects, thus the lifetime of equipment can be prolonged.
Point on wave closing method is mainly used in highvoltage systems. It is not
applied for lower voltage levels because of its complexity and high cost.
In my thesis I examine the feasibility of point on wave closing on low voltage
with injected pulse between the contacts. I create a control which is able to carry out
the process, furthermore, I examine how can the generated transient current in case of a
three-phase capacitor bank be minimized.
