When stator wedges are loose, this allows stator coils or bars to vibrate in the slot, leading to insulation abrasion and eventually a ground fault. Stator wedges are traditionally tested for tightness by tapping them with a hammer and listening to the sound produced. This method is slow and prone to inconsistency. Electronic evaluation of wedge tightness is faster, more accurate and provides more consistent results.
When coupled with SKF (Baker) 12kV Static Motor Analyzer AWA-IV/12 , the SKF Baker PP30 Power Pack extends the insulation testing voltage range. The PP30 is ideal for use in manufacturing, predictive maintenance, motor rewind and repair settings.
With the Fluke 1587/MDT FC Advanced Motor and Drive Troubleshooting Kit perform insulation tests, plus a wide-range of DMM tasks with confidence and ease. The kit also allows for the accurate measurement of AC current without breaking the circuit and checking the rotation of three-phase motors easily and safely.
Weak motor insulation often degrades to the point of causing premature and unexpected motor failure, which in turn can result in costly unplanned downtime of production machinery. The SKF (Baker) 12kV Static Motor Analyzer AWA-IV/12 is a fully-automated motor analyzer that automatically performs repeatable, user-programmable tests to thoroughly assess the strength of a motor’s insulation and circuit. The SKF AWA-IV/12 also used to assure quality of motor rebuilds or new production motors before they are placed into service.
