Product Overview Expands the capacitance and power factor/loss coefficient range for DELTA4000 devices Capable of tuning capacitances up to 1 μF at 10 kV Manual wheel adjustment Core gap sensor indicating the position of the inductance core Large wheels and handles for easy transportation Available adapter kits for use with older resonance inductor models Resonance inductors are connected in parallel to the internal power source of the test set. Manual adjustment changes the inductance to tune the parallel circuit to minimal load current. The resonance inductor is autonomous and air-insulated, housed in a robust metal enclosure welded along its length to withstand harsh field conditions. Large wheels and handles facilitate transport. Adapter kits are designed for users who already have a resonance inductor and need to connect the power factor meter DELTA4000.
