Some of our Special Features

FIBER GLASS COALESCING

Only Of Its Kind Semi-double Stage Degasification Chamber, delivering 40% efficient
degasification & dehydration then conventional single stage plant :–

Degasification & Dehydration is done in Macrotech’s transformer oil filtration plants mainly by FIBER GLASS COALESCING METHOD & then by RASING RIG technology. Glass fibers of 4 to 7 micron dia not only exposes each liter of oil into a corresponding surface up to 400 m2 area but sharp ends of glass fiber contributes to the evolution
of the gas from the oil break-up to gas bubbles. Thermo-Vacuum Treat, using the Fiberglass
Coalescing Method ensures Water removal from 50 PPM to 2 PPM and Gas removal from fully
saturated with air ( say 10% ) down to 0.1%. Upon that oil is made to pass from a well ventilated
Racing-Rig bed for complete removal of evolved moisture & gas to achieve unmatched result in
single pass.

Only of it’s kind FOAM REDUCTION System consisting of Foam Trap where from low density porous oil void spaces are removed , any left over dissolved gases are exhausted using the
vacuum pumping system & any vaporized or volatile oil body is sucked back in the DG chamber.

Ensuring No Foam Formation & allowing Ultra High Vacuum Operation.

Foam Trap

Transformer Evacuation System


The Separate Transformer Evacuation System has been designed to be used in multiple
ways as-

  • To substitute primary vacuum pumping system for filtration plant in case of breakdown.
  • Primary Vacuum Pumping set could perform transformer evacuation in case of breakdown of the
    later.
  • For faster evacuation of bigger transformers both vacuum pumping systems could be taken to
    use via any single evacuation outlet provided in the plant, while filtration unit is not running .

FLOW REVERSAL SYSTEM:

For reversing direction of flow of oil through transformer after 1st pass for uniform homogeneous mixing of oil &
also better removal of sludge.

HOT OIL CIRCULATION LINE:

For faster heating up of transformer windings before subjecting it to vacuum during drying of transformer.

PARALLEL OIL TOP-UP LINE LINE:

The Plants are capable of Parallel Oil Top-up of transformer while filtration of the same is running.

FLOW REVERSAL SYSTEM

SINGLE POINT OPERATION & MONITORING

SINGLE POINT OPERATION & MONITORING:

The entire transformer oil filter machine could be operated & monitored from a single point by one operator only.
All necessary valves & control devices are within reach of the operator standing in front of the
control panel. After easy manual startup the plant is capable of caring out fully automatic operation.

Dedicated Maintenance side:

An entire side of the plant has been fully dedicated for carrying out maintenance work. All the
pumps & motors are placed on this side, free from any obstruction for ease of servicing or dismantling.

Designed, Developed & Optimized with objective of—

  • Making the simplest machine of its kind. Every component in the filtration plant has been
    organized in a very uniform & logical way for easy understanding, operation & maintenance by
    even layman with very basic technical know-how.
  • Serving rugged environment of filtration sites for headache free operation.
  • Best possible operator comfort.

Frequently Asked Questions

  • Q. What is Mineral Insulating Oil or Transformer Oil ?

    • TRANSFORMER OIL IS A COMPOSITION OF SEVERAL HYDROCARBONS.
    • ITS MAIN CONTENTS ARE NAPTHANIC, PARRAFINIC AND AROMATICS HYDROCARBONS.

  • Q. Why Mineral Insulating Oil is used?

    Mineral insulating oil or commonly known as Transformer oil is used in Transformers , High Voltage Capacitors, Fluorescent Lamp Ballast & some type of High Voltage Switches & Circuit Breakers —

    • To provide dielectric strength.
    • To provide high flash point.
    • To provide High Insulating Resistance.
    • To provide efficient cooling.
    • To provide freedom from moisture & freedom from oxidation
    • To protect the transformer core and coil assembly from chemical attack.
    • To prevent the buildup of sludge in the transformer.

  • Q. How Transformer Oil gets contaminated?

    Transformer oil is liable to absorb un-acceptable contaminants formed inside high voltage instruments due to development of ageing products. Such as-

    • Formation of Acids due to Chemical decomposition.
    • Oxidation,
    • Formation of Gases.
    • Electrical stresses,
    • Thermal stresses,
    • Effect of oxidation products.
    • Moisture,
    • Solid Matters like Dust, Fibers, Metallic particles , Varnish and Sludge

    & also due to any kind of physical contamination as a result of leakage in the encloser of the instrument, etc

  • Q. Why oil filtration is required?

    When the concentrations of impurities are significant the oil has to be made fit for service by filtration . The process is made in a Filtration plant.  MACROTECH insulating oil reconditioning & filtration plant has been designed for High & Ultra High Vacuum and Low Temperature ( 450 C) of oil for achieving high parameter of oils as per IS-6034-1989 and IS-1866-2000.

  • Q. What are the benefits of oil filtration?

    • Insulating mineral oil is highly expensive oil, therefore replacing the oil is very cost effective & impractical but filtering this oil is not only highly economically profitable but also eco friendly.
    • With Presence of contamination in oil Performance & Life expectancy of extremely valuable High voltage Transformers are affected greatly. Contamination in Transformer oil can result in complete breakdown of the transformers worth millions. Whereas with good quality transformer oil transformers life expectancy could be enhanced by 200%.
