Generator, transmission and distribution transformers are some of the most critical and expensive assets in a power network. Moisture is a necessity in cellulose materials, but too much is absolutely detrimental to the service life of power transformers. Moisture, more specifically excessive moisture, has been enemy number one in power transformers utilizing cellulose insulation with insulating oil for a long time.
KVTEK developed a system (MAS10) that would remove moisture continuously in a gentle manner. A unique molecular sieve technique is applied to continuously remove moisture and particles from the transformer oil.
MAS10 system has the capacity to remove approx. 10 liters of water from a transformer before saturation, but the rate at which it will absorb water will depend on many factors, mainly, how much water is available in the oil, and the temperature range through which the transformer will operate. The design flow rate of the pumped oil is nominally 90 litres per hour to give maximum absorption through the molecular sieves.
|Model||No. of Cylinder||Suggested Transformer Size||Water Removal Capacity|
|MAS3||1||Less than 10 MVA||3 Litres|
|MAS10||3||10 MVA and Above||10 Litres|
|MAS30||3||50 MVA and Above||30 Litres|
