DESCRIPTION:IEEE North Saskatchewan IAS/PES Chapter is proud to present:\n\
 nTutorial/Technical Seminar on the Effects of Modern Variable-Speed Drives
  on Motor-Winding Insulation by Distinguished Lecturer Blake Lloyd.\n\nAbs
 tract - For over 70 years\, researchers have understood that fast rise-tim
 e voltage surges from a circuit breaker closing can lead to an electrical 
 breakdown of the turn insulation in motor stator windings. Rapid advances 
 in power electronic components in the past decade have lead to a new sourc
 e of voltage surges. Inverter-fed drivers (IFDs) of the pulse width modula
 ted (PWM) type that use insulated-gate bipolar junction transistors (IGBTs
 ) can create tens of thousands of fast rise-time voltage surges per second
 . Anecdotal evidence suggests that the large number of voltage surges from
  IFDs can lead to gradual deteriorations and eventual failure of the turn 
 insulation—both in low voltage (less than 1\,000V) and medium voltage (2
 .3 to 4.16kV) motors . This presentation describes the characteristics of 
 voltage source PWM drives Impact on random wound (LV) motor stators as wel
 l as the impact on form wound (MV) stators. It will also describe the rele
 vant standards to qualify insulation systems for converter fed motors .\n\
