customer’s specific requirement, such as moreflow-rates. Theseplants work on low temperature, high
vacuumprinciple. Plants mainly consistof heating, filtration and vacuumsystem. Heating systemaids to
the filtration and moistureremoval. Filtration systems removesuspended particles down to 1 micron such
as rust, dirt, scales, colloidal carbon etc. VacuumSystems removemoisture(emulsified as well as
dissolved) down to < 5 – 10 ppm depending on the working vacuumof the plant.

High Vacuum Transformer Oil Filtration

Trickle ImpregnationTechnique
• Trickle Impregnation Technique
• In today’s competitiveworld the electrical insulation materials and the processes areviewed with
tremendous costand quality consciousness. Varnishing of electrical machine winding forms a major part of
the total costof the electrical insulating materials. With the increasing costs of energy and solvents for use
in varnishing, it has become a need of the hour to look into the change in the conventionalimpregnation
methods such as Dip and bake varnishing or the Vacuumimpregnation.
• On this background Trickleimpregnation technique was evolved to improvethe varnishing quality coupled
with reduced cost. This technique is now well accepted and used for impregnating stators /fields and
armatures / rotors in all the advanced countries
• Trickle Impregnation Technique :
• According to the principle of Trickle Impregnation, activated resin is trickled in a thin jet on to the rotating
preheated winding. The resin immediately gets heated and its viscosity is reduced. Due to the rotary
motion of the winding the resin gets distributed evenly inside the winding without any drain loss. The
heated winding accelerates the gelling and curing of the resin.

Batch Type Trickle Impregnating Machines
Trickle Varnish Impregnating Machineis suitable for pre-heating, trickling and postheating of stators. The
machine is simple and compact in design. Itis easy for operation and maintenance. Itis ideally suitable for
batch type production of stators. Themachine is suitable for carrying out following automatic cycle
• Load stators on spindles, connectwinding wires, closethe frontdoor and start cyclewith push button.
• Spindles start rotating and get pre-heated to predetermined temperature.
• Temperature of stator is sensed by non contact TIC.
• Spindle holding plate is tilted up and varnish pipes are tilted down to adjustthe place of trickling.
• Varnish pump starts and predetermined varnish is trickled on stators /rotors and pump stops. Trickle
Temperature is maintained with the non contact TIC
• Spindle holding plate is tilted down and varnish pipes are tilted up and postheating starts.
• After completing the postheating spindles, stop.
• Open the door & removewire connections and Un-load the ready stators.

Batch Type Trickle Impregnating Machines

Index Type Trickle Impregnating Machine
• Trickle Impregnating Machines aresuitable for automatic impregnating of stators and rotors by trickle
process. Stators and Rotors areheated to pre-determined temperatureand then trickled with varnish
(Resin + Hardener) and cured until it hardens. They are then ready for unloading manually. They are
rotated by chain drivewhich rotates the spindles mounted on rotating / indexing table at an appropriate
speed suitable for trickling. Indexing Table is rotated by motor with gear box and limit or proximity
switches.
• Job Indexing System: Indextable is mounted on a spindle placed in fabricated box containing main spindle
bearings. Itis indexed with the help of brakemotor, gearbox, chain, and main spindle. The index position is
ensured by spring loaded index pin operated by pneumatic cylinder, proxy switch, reed switch & PLC.
• Job RotationSystem: Rotating spindles are mounted on the index table driven by electric motor, gearbox,
chain and sprockets. An arrangementis provided such that when jobs cometo loading - unloading station,
spindles stop rotating for easy removaland placement.
• Heating System: Stators and Rotors arepreheated and cured while passing through the preheating zone
and postheating zone. Radiation type electric heaters do heating in pre-heating and curing zonewith

carried out in following steps and will be generally as per the schematic diagramattached.
• Pre-heating the jobs in either Impregnation Chamber or in Oven if you have a less time available.
Evacuation of Impregnation Chamber (after putting the jobs) to make the voids in the jobs clear and drying
of jobs for specific time & required temperature/ vacuum.
• Induction of impregnant (Varnish) in the Impregnation Chamber from impregnantTank to submergethe
jobs in it.
• Pressurizethe Impregnation Chamber with dry air or nitrogen to fill the voids with Impregnant.
• Return the varnish to ImpregnantTank.
• Cure the jobs either in Impregnation Chamber or in Oven for specific time if time available is less.

Industrial Oil Purification Systems
IndustrialOilPurification Systems Oilpurification systems aredesigned & manufactured to suit the specific
requirementof the customer. Normally the oil is deteriorated by contamination of foreign particles, moisture
(free& dissolved), oxidation sludge etc. The deteriorated oil affects the performanceof the equipment in which
it is used because of change in properties. Differentmodules are designed to removeparticular types of
contaminations. The purification systemnormally consists of filtration / purification stages for economical
operation. In prefiltration stage coarseparticles are removed using cleanable / washableelements. In
intermediate stagethe major portion of the contaminants removed by using the properly selected filter
elements suitable for oil to be purified. In final stage the fine contaminants areremoved by special elements to
suit the final application and purification level. The freemoistureremovalis carried out either by gravity
separation methods such as spirafuge, centrifugeor by using coalescer elements. Dissolved moistureis
removed partially by coalescer elements and finally by vacuumtreatment.

• Why usetransformer oil?
• Transformer oilis used as liquid insulation and dissipates transformer heat. Morespecifically, the
transformer oilis used as a coolantin transformers and as a means of arc suppression in circuitbreakers
(apartfromits insulating properties).
• Transformer oilnotonly helps to preservethe coreand windings which are fully immersed with oil, but
also prevents directcontact of atmospheric oxygen which causes oxidation of the cellulose made paper
insulation around the windings.
