Abstract
An apparatus for measuring the rate of CuS formation in power transformers comprising a sealable transformer vessel and a sealable lid with at least four sealable ports, and an internal apparatus configuration involving a copper metal sheet, a power transformer, a temperature sensor, and a weighing device providing real-time feedback data, whereby these components are submerged in an effective amount of a reactive sulfur-containing transformer oil and sealed. An inert gas atmosphere is provided within the transformer vessel by a gas bubbler. The transformer oil is heated with a heating bath to a reactive temperature for CuS production. A method of measuring the rate of CuS formation whereby the apparatus is purged with an inert gas, heated to a reactive temperature, examined for CuS formation, the CuS produced is quantified and the rate of formation of CuS is calculated.
