Controlling partial discharge in high voltage motors and generators

There’s an increasing trend for plants to stipulate low partial discharge (PD) when they specify high voltage motors and generators. Unfortunately, this is not an effective way of tackling partial discharge. It leads to higher costs and overdesign, but it won’t necessarily ensure a longer lifetime or increased reliability. Our white paper highlights a number of ways in which motor and generator users can control partial discharge.

The white paper consists of six chapters:

  • Introduction - what causes partial discharge
  • Key roles for design, materials and workmanship
  • Detecting and measuring PD
  • Condition monitoring and service
  • Does it make sense to stipulate low PD levels?
  • Conclusion
