Electrical discharge detector pen
Electrical discharge detector pen TKED 1
The SKF Electrical Discharge Detector Pen (EDD Pen) is an easy-to-use handheld instrument for detecting electrical discharges in electric motor bearings. Electrical discharges are caused by motor shaft voltages discharging to ground through the bearing, resulting in electrical erosion, lubricant degradation and ultimately bearing failure.
Electric motors are more susceptible to electrical erosion in their bearings when controlled by a variable frequency drive. When incorporated into a predictive maintenance programme, the EDD Pen can help identify bearings that are more susceptible to failure and can significantly help prevent unplanned machine downtime.
A unique remote solution enables operation at a distance from the motors. This helps protect the user from coming into contact with moving machinery.
No special training is required.
Can detect electrical discharges over a time base of 10 seconds, 30 seconds or indefinitely. The backlit LED display enables use in dark environments.
IP 55 rating enables use in most industrial environments.
Supplied as standard in a carrying case with batteries, spare antenna and multilingual instructions for use.
