Resonating Inductor

Expands the range of Capacitance and Power Factor Test Sets

Capable of tuning capacitances up to 1μF at 10 kV

The Resonating Inductor is an accessory for use with the semi-automatic 12 kV Extended-Range Capacitance and Dissipation Factor Test Set, or the Automated Insulation Power Factor Test Set (DELTA-2000).

The Resonating Inductor is used to expand the capacitance range of these test sets and cannot be used with the standard 12 kV Capacitance and Dissipation Factor Test Set.

The Resonating Inductor is connected in parallel with the internal power supply of the test set. A manual tuning wheel on the Resonating Inductor varies the inductance to tune the parallel circuit for minimum load current.

The Resonating Inductor is self-contained and air-insulated. The housing is a sturdy metal enclosure welded throughout to withstand the rigors of field operation. Large wheels and handles are provided for convenience in transportation.
