The relationship btw dielectric strength and temperature

Click For Summary
SUMMARY

The discussion centers on the relationship between dielectric strength and temperature, highlighting a lack of mathematical evidence supporting this correlation. Participants reference various studies, including one from ResearchGate, which examines low temperature and moisture effects on oil-paper insulation dielectric response. Despite finding some research on conductivity's temperature dependence, the connection to dielectric strength remains unclear. The need for mathematical elucidation on this topic is emphasized, particularly in relation to dielectric constants.

PREREQUISITES
  • Understanding of dielectric strength and its significance in electrical insulation.
  • Familiarity with temperature effects on material properties.
  • Knowledge of electrical conductivity and its relationship with temperature.
  • Basic comprehension of research methodologies in electrical engineering studies.
NEXT STEPS
  • Research the mathematical models linking dielectric strength and temperature.
  • Examine the paper titled "Low Temperature and Moisture Effects on Oil-Paper Insulation Dielectric Response in Frequency Domain" for relevant data.
  • Investigate the dielectric constant's temperature dependence and its implications for dielectric strength.
  • Explore additional academic papers that provide mathematical analysis of dielectric properties under varying temperatures.
USEFUL FOR

Electrical engineers, materials scientists, and researchers focused on insulation materials and their performance under temperature variations.

Wiki suggests dielectric strength is temperature dependent, but I've yet to find any math supporting this. I found some math corroborating a relationship between conductivity and temperature, but whether or not there's any causality between conductivity and dielectric strength has eluded me. Any help with solving this mystery is greatly appreciated!

Perform a Google search on the terms ("dielectric strength" "temperature effect" math). One of the cites that may be of use is "https://www.researchgate.net/publication/224563706_Low_Temperature_and_Moisture_Effects_on_Oil-Paper_Insulation_Dielectric_Response_in_Frequency_Domain".

Thank you for the response! I've googled "dielectric strength and temperature dependence" recently and read a few papers researching the phenomena. But few included math measuring the effect of temperature changes on dielectric strength. Could you elucidate the math in the paper you've posted? I found a similar study with math included, but its for the dielectric constant instead of strength. The math can be found in the results section of the paper.
