The active sulphur compounds in transformer oil would react with copper wires and produce
cuprous sulphides, which then attach themselves to the surface of copper wires and …

A mineral insulation oil containing 500 mg/l dibenzyl disulfide (DBDS) was aged under
different thermal (105° C to 165° C) and atmospheric (nitrogen and air) conditions to further …

The failures of high-voltage transformers and reactors can result from the deposition of
copper sulfide on the oil-impregnated paper insulation. This study explored the influence of …

Oil-paper insulation plays an important role in the internal insulation of power transformers.
Aging of transformer insulation is a gradual procedure which can eventually threaten the …

Since a number of failures have happened on transformers and reactors due to the corrosive
sulfur problem, especially for Dibenzyle-disulfide (DBDS) in mineral insulation oils, many …

In power transformers, the main reason why insulation faults occur is that partial discharge
(PD) produces insulation deterioration at the weakest point of the insulation structure and …

The development of reliable, environmentally safe and economically viable insulating oil for
transformers is an endless effort of the electrical industry. Recent research is based on …

SunOS 5.0 is the operating system component of Solaris 20. SunOS 50 contains the kernel
support for multiple threads of control in a single process address space. This allows a …

Development and manufacturing of a reliable, economically viable and environmentally
sustainable and effectively acceptable insulating oil to be used as an insulating and heat …
