Study on Breakdown Voltage for Vegetable Oils With Additive TiO2

Influence of Copper Particles on Breakdown Voltage and Frequency-Dependent Dielectric Property of Vegetable Insulating Oil

The insulating performance of oil is vulnerable to particles especially the conductive particles. This paper investigated the influence of copper particles of micrometer size on the breakdown strength and frequency-dependent properties of vegetable oil. The AC breakdown voltage of contaminated vegetable oil with copper particles of different numbers (ranging from 103 to 106) was measured. The f...

Lubricant basestocks from vegetable oils

Oil Chemical Research. USDA l-ARS-NCAUR. 1815 N. U;liuersity Street, Peoria, IL 61604, USA Accepted 8 October 1999 Compared to the lubricants made of petroleum, vegetable-based lubricants are much more biodegradable but inferior in many other technical characteristics. The basestock typically contributes to more than 80% of lubricant and must meet performance criteria in such aspects as cleanli...

Progress in Vegetable Oils Enzymatic Transesterification to Biodiesel - Case Study

Study of the applicability of vegetable oils in phytocosmetology

Vegetable oils are a class of natural products very frequently used in phytocosmetology. Natural remedies with antiaging action are very popular in our days. Harmfulness of natural compounds on the skin, is quickly observed by the 24-48 hour patch test skin irritation and erythema measurement. Changes in the concentration of melanin and sebum in the dermis, represent real parameters which give ...

Breakdown Voltage of High-voltage GaN FETs

GaN FETs offer superior advantages in high-voltage and high-temperature operation due to its large bandgap (3.4 eV) and high breakdown field strength (3.3 MV/cm). This combination of the large bandgap and high breakdown field makes these devices very attractive for power switching applications. In this regard, a key figure of merit is the breakdown voltage of the transistor, which must be high ...
