Resonating inductor | Capacitance Range Extenders
The resonating inductor is an accessory used to expand the capacitance range of the DELTA4000 automated insulation power factor test sets.
- Expands the range of capacitance and power factor/dissipation factor for DELTA4000 units
- Capable of tuning capacitances up to 1μF at 10 kV
- Hand-crank tuning wheel
- Core gap gauge that displays position of inductor core
- Large wheels and handles for easy transport
- Adapter kits available to use with older Resonating Inductor models
The resonating inductor is connected in parallel with the internalpower supply of the test set. A manual tuning wheel on theresonating inductor varies the inductance to tune the parallel circuitfor minimum load current.
The resonating inductor is self-contained and air-insulated.The housing is a sturdy metal enclosure welded throughout towithstand the rigors of field operation. Large wheels and handlesare provided for convenience in transportation.

APPLICATIONS
Capacitance and dissipation factor "power factor" testingis used to determine the quality of electrical insulation.
The insulating quality of electrical insulation may deteriorate due tomanufacturer's defects, contamination, physical damage, in-service fault conditions or normal aging.
When the insulating quality of electrical insulation deteriorates, leakage paths develop that allow current to pass through the insulation.
Dissipation factor measurements are used to detect these problemsbefore complete insulation breakdown occurs.
The Resonating Inductor allows the user to perform capacitance and dissipation factor tests on such high-capacitance items as large motors, large generators and long cable runs.
Dissipation factor testing also can be performed on transformers, bushings, circuit breakers, insulators, capacitors, surge arresters, insulating liquids or any other type of equipment that contain selectrical insulation.
