Transformer oil input device
During detection of total gas content (air) and transformer oil moisture content direct insertion of transformer oil into the evaporator of chromatograph is used. At that sample volume is up to 25 mcl, evaporator temperature is 250-350°C. Main problem with such insertion is protection of chromatographic column from transformer oil. Special evaporator serves for this purpose with possibility to accumulate the oil at the bottom of evaporator and then discharge this oil, and replaceable precolumn that protects the column from the remains of oil that went through the evaporator.
