OIL PURIFICATION SYSTEMS
Water is one of the biggest enemies of the transformer lifetime. Mainly it gets absorbed in the cellulose insulation (reducing its mechanical strength) some part gets dissolved in the oil and some part can exist as free water. At higher temperatures the water which is absorbed in the cellulose moves to the oil and reduces its breakdown voltage which...
Oil is the most sensitive material inside the transformers. It can get wet from water ingress, there are lot of chemical reactions which are happening inside the oil and as it serves as coolant and dielectric media- gasses are formed inside the oil.
The transformer oil, water ingress, improper maintenance , small faults inside the transformer , chemical reactions of the materials at elevated temperatures , gasses formations due to molecules rebounding under electrical stress and heat all lead to oil degradation. This si a catalytical effect and this process is speeded up with time and the result ...
PCB or Poly Chlorinated Biphenyl are additives which some of the transformer oil manufacturers used in the past century to increase dielectric properties of the transformer oils. Not all transformers had such oiled but many of them were treated with machines that were used for treating transformers with PCB ( which resulted in small dosage) , many of them were ...
ENERVAC Varnish Removal Systems (VRS) were developed to properly remove varnish commonly found in various lubrication and hydraulic systems. Our process utilizes either granular adsorbent media or depth media filter elements to remove dissolved and suspended oil degradation.
ENERVAC’s Type 2E Dryers consist of two identical pressure chambers filled with desiccant and an external heater for continuous removal of water vapor from compressed air or gases to -40°F (-40°C) dew point or lower. They are capable of processing gas, from 0-100% of the design inlet flow rate, without adjustment.
Sulfur Hexafluoride (SF6) is an excellent gaseous dielectric for high voltage power applications. It has been used extensively in high voltage circuit breakers and other switchgear employed by the power industry. Applications for SF6 include gas insulated transmission lines and gas insulated power distribution substations. .
