TRANSFORMER OIL INPUT DEVICE
When determining the total gas content (air) and humidity of transformer oil, direct injection of transformer oil into the evaporator of the chromatograph is used. The sample volume is up to 25 µl, the evaporator temperature is 250-350 °C. The main problem with such an input is the protection of the chromatographic column from transformer oil. For this purpose, a special evaporator is used with the possibility of oil accumulation at the bottom of the evaporator and its subsequent discharge, and a replaceable pre-column that protects the column from oil residues that have passed the evaporator.
technical specifications
The volume of the evaporator is 10 ml.
The number of replaceable pre—columns in the device kit is 5.
The temperature of the evaporator is from 250 to 350 °C.
The possibility of draining the transformer oil accumulated in the evaporator.
