We conduct a range of electrical tests to evaluate the characteristics of plastics, composites (i.e. NEMA LI), tapes, resins, coatings, laminations, ceramics and various insulating materials.
Test programs range from standard ASTM test methods to custom designed research programs. Most tests can be conducted in a temperature-controlled environment ranging from ambient to 300°C. We offer high-voltage capacity up to 150 kV.
- Dielectric Breakdown
- Dielectric Constant
- Dissipation Factor
- Dielectric Strength (air or oil)
- Surface and Volume Resistivity
- Megger Testing (up to 100 Tera Ohm range).
We perform ASTM 149, ASTM 150, ASTM D229, ASTM D257, NEMA LI-1 and customer-specific quality control and qualification testing. The rigorous quality assurance requirements mandated by ISO 17025, 10 CFR 50 Appendix B (nuclear) and Nadcap (aerospace and defense industry) are applied to every job we perform.
Quality Control Testing of Insulation Systems
The integrity of insulation systems must be verified to prevent loss of power generation and catastrophic equipment failure. Properties including insulation dissipation factor, breakdown voltage, physical and chemical analysis results provide the confidence required to install items such as stator bars in the field.
Lucideon has extensive experience performing failure analysis of electrical insulation systems for the nuclear industry. We routinely identify the composition of contaminants, check for leak paths, assess bonding conditions, and determine the root causes for premature insulation failures to support complete generator failure investigations.
