Condition assessment of the electrical insulation in a high voltage current transformer using an oil/sand mix.

A reliable, uninterrupted power supply that can cope with the rapid increase of electrical energy consumption by today?s electricity consumers and other industry stakeholders is a priority for any power supply organization. Modern power systems within this industry consist of many components, among them instrument transformers (current and voltage transformers and metering units). These play crucial roles in the control, protection and monitoring of a power transmission system. Typically, the number of installed instrument transformers in any network is more than tenfold that of installed power transformers. [ABSTRACT FROM PUBLISHER]
