Electrical Testing of Insulating Materials

Service Detail from M+P Labs

Electrical Testing of Insulating Materials-Image

M+P Labs has expertise in conducting a range of electrical tests to evaluate the characteristics of various insulation systems. 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 oC. We offer high-voltage capacity up to 150 kV. Testing includes:

  • Capacitance
  • Dielectric Breakdown
  • Dielectric Constant
  • Dissipation Factor
  • Dielectric Strength (air or water)
  • Inductance
  • Surface and Volume Resistivity
  • Megger Testing (up to 100 Tera Ohm range)

Qualification Testing:

We perform ASTM 149, ASTM 150, ASTM D229, ASTM D257, NEMA LI-1 and customer specific Quality Control and Qualification testing.

Failure Analysis:

M+P Labs has extensive experience performing failure analysis of electrical insulation systems, particularly for the power generation industry. We routinely identify the composition of contaminants, check for leak paths and determine the root causes for premature insulation failures.

Additional analyses and testing capabilities available at M+P Labs include:

The chemical, thermal, mechanical, metallurgical, and microstructural analysis capabilities available at M+P Labs can be used in conjunction with electrical property characterization to help solve your most challenging materials and processing problems or qualify products for use or sale.
