SKF Antenne pour détecteur de passage de courant TKED 1-1

Replacement antenna for the SKF Electrical Discharge Detector Pen (EDD Pen). A simple to use hand-held instrument for detecting electrical discharges in electric motor bearings. Electrical discharges are a result of motor shaft voltages discharging to earth through the bearing, causing electrical erosion, lubricant degradation and ultimately bearing failure.
