The 2303 Induced Voltage Filter (IVF) is an indoor rated 60 Hz sheath grounding unit.
The IVF is a tuned series pass network which provides a low impedance path to ground for induced 60 Hz AC current. Tone locating and cable monitoring signals pass by the IVF with little or no reduction in strength.
