Benzoil - One of Transformer Oil Supply
Specialists in Melbourne

• Benzoil is among Australias few specialised
  transformer oil suppliers, and we consider
  ourselves well placed in the oil market to offer
  helpful advice, particularly if you are looking
  to buy. Transformer oil is a dielectric fluid is
  used in oil-filled electrical assets including
• Transformers
• High voltage capacitors
• Circuit breakers

3

• The function of transformer oil is to insulate
  and cool, and serves to
• Prevent electrical discharges between the coils
• Remove heat generated by the operation of a
  transformer

4

• Transformer oil can be considered a technically
  complex product, and we can explain the meaning
  and significance of the various physical,
  chemical and electrical properties including
• Moisture Content
• Interfacial Tension
• Flash Point
• Viscosity
• Pour Point

5

• Neutralization value
• Oxidation Stability
• Corrosive Sulphur
• Dielectric Strength
• Specific Resistance
• Dielectric Dissipation Factor

6

• Although vegetable and synthetic variants are
  available, Benzoil chiefly offers mineral based
  transformer oil for sale. When your business
  needs to buy transformer oil, Benzoil can supply
  electrical insulating oil for all applications
  and meeting any international or Australian
  specification. Depending on the purpose,
  transformer oil may be required to meet not just
  technical requirements, but also environmental
  and price points.

7

• We offer 3 tiers of transformer oil comprising
• Virgin (i.e. refined from crude)
• Re-refined (i.e. refined from previously refined
  (virgin) oil)
• Regenerated (i.e. physio-processed from
  previously refined (virgin) oil)

8

• We welcome one-off sales enquiries as well as
  ongoing supply requirements. Typical users
  include power utilities, OEMs, and service and
  maintenance companies. Transformer oil is
  usually ordered in bulk and delivered by
  specialised road tankers or ISO containers. We
  can also supply in sizes including
• 1,000L (IBC or pallecon)
• 205L (drum)
• 20L (small drum)

9

• We provide a NATA accredited laboratory
  certificate of analysis with all orders.
• An oil for all occasions
• Benzoil is among Australias few specialised
  transformer oil suppliers, and we consider
  ourselves well placed in the oil market to offer
  helpful advice. Read more about virgin and
  re-refined transformer oils.
• Regenerated and made good as new
• Regenerated transformer oil is a naphthenic
  transformer oil which has been regenerated to
  restore physical, electrical and chemical
  qualities back to as new condition. Read more
  about regenerated transformer oils.

• Specifically designed oil for industry
• In conjunction with leading transformer OEMs
  and electric utility companies, Benzoil has
  developed a unique product designed specifically
  for flushing and rinsing electrical transformer
  internals. Read more about transformer flush
  oils.

• Learning about oxidation, the primary
  mechanism of oil degradation
• In a transformer, oil oxidation is a chemical
  process which must be readily be kept in check.
  The culprit oxygen is introduced from the
  atmosphere and/or is released from the cellulose
  based transformer paper insulation in the
  presence of heat. Oxidation is normally first
  associated with the oil as it deteriorates, and
  can be controlled but not eliminated. Oil
  oxidation, heat and moisture work in combination.
• Oxidation by-products will destroy the paper
  and cause the formation of sludge which will lead
  to overheating and ultimately, premature failure
  of the asset.

12

• Oil degradation releases a range of chemical
  substances that react and breakdown the
  cellulose. These reactions accelerate in a chain
  effect each adding to the ongoing destruction
  of the cellulose. The porous nature of
  insulating paper and board react to the decay
  products as adsorbents.
• It is well recognised that even low acid
  levels in oil have a major effect on oxidation
  and the degradation of the paper insulation in
  transformers. New oil has an acidity of less
  than 0.03mg KOH/g and it has been shown that oil
  with acidity 0.05mg KOH/g will start to cause
  decay of cellulosic insulation. The most cost
  effective point at which to reclaim that oil is
  at this time and certainly should not be delayed
  beyond acidity 0.1mg KOH/g.

13

• When acidity moves beyond 0.2mg KOH/g the oil
  and insulation degradation process is accelerated
  and will usually be accompanied by the formation
  of sludge on the core and coils of the
  transformer. At these levels acidity will tend
  to increase exponentially with increased time at
  normal transformer operating temperatures. These
  high acid numbers are devastating to the tensile
  strength of the paper.
• Oxidation can be kept in check by regular
  monitoring of oil condition, and Benzoil can
  provide this service in conjunction with our
  partners.
