In high-voltage var compensation field, when switching the capacitor banks by mechanical switch, it is easy to bound when it closes and to restrike when it opens, and the mechanical switch can not be switched frequently. When switching the capacitor banks by electronic switch in series, it needs dynamic and static voltage sharing circuit and synchronous triggering circuit. It leads to complex structure and high cost.
