Excessive Moisture in your Transformer? We can help

Generation, Transmission and Distribution Transformers are some of the most critical and expensive assets in power network. Moisture is a necessity in cellulose materials, but too much of it is 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.
In modern-day networks, Transformers are increasingly overstressed due to power demands. These instances are now more frequent and occur much more frequently than in the yester era. The impact of this on a Transformer deemed ‘wet’, is that it has a much higher possibility of failure. This is primarily due to moisture being driven out of the cellulose faster than what the mineral oil can absorb, creating a very low dielectric (voltage withstand capacity) in confined spaces in the windings. The consequences are normally catastrophic.
Ageing and degradation in Power Transformers create moisture, acid and sludging, all contributing to weakening of the insulating system, thus increasing the risk of shortening the normal service life.
KVTEK developed a system Moisture Absorption System (MAS10) that would remove moisture continuously in a gentle manner. A unique molecular sieve technique is applied to continuously remove moisture from the Transformer oil when the transformer is in use i.e. in on-line condition.
MAS10 operates in an outdoor location with on-line transformer or reactor on a continuous basis. The cylinders housing molecular sieves are made of stainless steel, and hence needs no additional protection. The pump to circulate oil is designed for continuous operation. Although the electrical connection box has a rating of IP45, Stainless Steel cover offers total environmental protection for the electronics which increases the rating to IP65. MAS cylinders will continue to absorb water from the oil until saturation is reached.
Now your LIFE OF TRANSFORMER is extended with the MAS-10.
