	i have no any document from TR manufacturere, But i have IEC standard 60076 part -II for temperature rise test. According to that i need to perform this test upto when 1deg.C temperature variation. after that remove SC and measure temp. up to 15min. From this two reading i do some mathematical cal and plot one graph for it.
