High Voltage Winding Best Practice Training

Training description

The High Voltage Winding Best Practice training is a 2 days training that includes 4 sessions.

  1. Basic AC machine design theory & constrains
  2. HV Coil insulation & control of partial discharge
  3. HV Coil manufacturing & testing
  4. HV Winding best practices

Session 1: Basic AC machine design theory & constraints

Design constraints - Critical design area

  • Active surface area D2L, Amperturns/cm, flux & current densities etc
  • Coil pitch factors
  • Winding distribution factors
  • Induction machine winding connections
  • Consequent poles
  • Lap & wave winding connections
  • Concentric windings
  • Star / Delta connections
  • Control of stray losses using transpositions

Session 2: HV Coil insulation & control of partial discharge

HV Coil insulation basics

  • Requirements for coil insulation
  • Introduction to dielectric stress
  • Introduction to partial discharge
  • Insulation temperature classes
  • Introduction to mica

HV hot press coil design
Control of partial discharge

Session 3: HV Coil manufacturing & testing

Visual examples of different coil types
Examples of typical coil data sheets
HV Coil manufacturing

  • HV coil insulation design
  • Production of insulated rectangular conductor
  • Coil shaping & insulating; Lap, concentric, half-bar
