Abstract: A mechanically variable high reactive power inductor is described for testing capacitive loads, such as high voltage electrical power transmission cables or large capacitors. The inductor is formed of upper and lower separable core segments magnetically coupled to electrical windings. The cores are separated in an accurate stable manner to change the inductance of the inductor to tune the inductor into resonance with the capacitance of the load being tested to obtain effectively a series resonance condition therewith. The upper core segment is suspended from lead screws which are jointly operated by a control capable of varying speed to establish accurate gap control for improved high voltage testing capability.
