CJC VacuumFilter
The CJC V30 VacuumFilter is designed specifically for de-watering and de-gassing transformer oil. The V30 employs an offline oil maintenance process which allows the transformer to remain in use for a safe, easy, and permanent solution to transformer maintenance.

FUNCTION
The CJC
TM Vacuum Filtration Unit (de-gassing unit) consists of a vacuum chamber and a filtration insert. A vacuum pump maintains the pressure in the chamber at the lowest possible level. At such low pressure even water turns into a gas and the gas content of the oil is radically reduced during its stay in the vacuum chamber.
When the oil is pumped back into the transformer it is absolutely dry. The water content is very close to 0 ppm. The water content of the oil maintains equilibrium with the water content of the cellulose; consequently, when the oil is dried, water will transfer from the cellulose to the oil in order to satisfy the equilibrium.
The water starts to travel through the cellulose via the oil bordering surface into the oil phase. The travelling speed of the water in the cellulose can only be influenced by one factor: the temperature. That is why all de-gassing (de-hydration) should be performed while the transformer is in operation. The speed of dehydration is affected by the travelling speed of the water through the cellulose - hence, the dehydration must be allowed ample time. The longer time a dehydration process is allowed, the better the result, which is why continuous de-gassing is very advantageous.
When the acid contents are reduced the ageing speed of the cellulose and of the oil is reduced accordingly. As an immediate consequence the generation of water is minimized which, in turn, reduces the water content of the cellulose.
OPERATION
V30's have been operating successfully around the world for several years. For this year, CC Jensen has taken the proven V30 and added a powerful user interface, utilizing a flat panel touchscreen for controls, monitoring, and troubleshooting. The V30 has also gotten smarter, now able to control all its own parameters to optimize the dissolved gas and water reduction process, further highlighting the V30's 'Plug n Play' nature.
