| Abstract: |
| This paper will discuss the elusive failure mode of high voltage products - dielectric breakdown. Typical measurements, such as, primary-secondary resistance, primary-secondary inductance, turns ratio, etc. will not be addressed. |
| Failure mechanisms in high voltage coils originate in the design, winding, assembly, vacuum encapsulation and curing processes. The mechanisms are time and temperature related. In-house testing to sort out potential defects is difficult and time consuming. Reliability must be designed and built into the coil. |
