SKF Electrical Discharge Detector Pen TKED 10 pages

Unique, reliable and safe method to detect electrical discharges in electric motor bearings

SKF Electrical Discharge Detector Pen TKED 1
The SKF TKED 1 (EDD Pen) is 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.
Electric motors are more vulnerable to suffer electrical erosion in bearings when
controlled by a Variable Frequency Drive. When incorporated into a predictive
maintenance programme, the EDD Pen can help detect bearings more susceptible
to failure, and to a significant degree, prevent unplanned machine downtime.
•t Unique remote solution allows operation at a distance from the motors.
This helps protect the user from touching machinery in motion.
•t SKF developed technology. 1)
•t No special training required.
•t Capable of detecting electrical discharges on a time base of 10 seconds,
30 seconds or infinite.
•t LED backlit screen, allows use in dark environments.
•t IP 55 can be used in most industrial environments.
•t Supplied standard with batteries, a spare antenna and language-free
instructions for use in a carrying case.
