摘要
An apparatus for measuring the rate of Cu2S 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 Cu2S production. A method of measuring the rate of Cu2S formation whereby the apparatus is purged with an inert gas, heated to a reactive temperature, examined for Cu2S formation, the Cu2S produced is quantified and the rate of formation of Cu2S is calculated.
