With the increase in capacitor voltage transformer (CVT) operation life, CVT impedance changes, and the short-time switching of overhead lines, it is very easy to cause a transient oscillation accident in which a CVT participates, reduce the insulation level of a CVT, and even induce regional power grid oscillation and easily cause capacitor …

Above the resonant frequency it is "more like an inductor than a capacitor". What that graph represents is the measured reactance translated back to a capacitance. As we approach resonance the inductive reactance cancels the capacitive reactance and the effective capacitance increases (theoretically going to infinity at …
