Oil Immersed Transformer Overload Capacity

Oil Immersed Transformers are able to withstand rather large degrees of overloads; near 30%.  To do this sufficient information must be understood to verify reliable safe parameters.  Studies have been made to establish these guidelines.  A number of factors must be considered when designing, building, installing and servicing oil cooled and oil insulated transformers.  Adequate operational data on Oil Immersed Transformers has resulted in the following.

Oil Immersed Transformer Protective Measures

Oil Immersed Transformers may have their life extended through a number of simple steps.  These measures include:

  1. Maintaining cooling system at optimum efficiency

  2. Checking windings and oil for concentrations of sludge and moisture

  3. Insuring the absence of oil duct restrictions, obstructions and reduced clearances

  4. Augmentation of air cooling by appropriate changes to the cooling system

  5. Centering modifications to cooling systems around predictable hotspot temperatures (by consulting with the manufacturer)

  6. Operation within known tolerances to temperature rise for the particular transformer involved

  7. Operation with due regard given to specific limitations of oil expansion, pressure within a sealed unit, heating of a variety of parts (including bushings, tap changers, leads, cables, circuit breakers, reactors, switches, transformers, and soldered connections)

Oil Immersed Transformers Hotspots

All Oil Immersed Transformers inherently have points which heat more quickly or chronically than others.  These are considered hotspots.  These will usually directly relate to the fastest aging points in the paper insulation.  Loading affects on life of Oil Immersed Transformers is directly influenced by the primary factor of the hottest spot in the windings.  It is logistically impractical to measure the hottest spots directly, so a calculation has been evolved in which a conservative estimate can be applied.  One sums the oil temperature with avg. temp. rise of copper and a hot spot allowance.  This allowance is figured at rated load and is given as 10ْ C in transformers having 55ْ C avg. winding temp. rise by resistance and 15ْ C for those having 65ْ C rise by resistance.  (Note: these parameters are applicable except for pre-1929 water-cooled transformers.)

Temperature Sensors And Relays In Oil Immersed Transformers

Top oil temperature gauges in older Oil Immersed Transformers do not measure hotspot temps.  Built in devices that can indicate and record these are installed in modern Oil Immersed Transformers.  Relays are also connected in so as to automatically enable starting of fans and oil pumps at a low temperature, activate an alarm at a middle temperature, and activate breakers for shut off at a high temperature.  They adjust for use with either version of transformer; 55ْ C rating or 65ْ C rating.

Other Factors In Heating And Operational Temperatures For Oil Immersed Transformers

Air Temperature–  If air is used as a cooling medium, then air temperature must be considered.  Ambient temperature will affect permissible operational loading.  Tables should be available through the manufacturer to guide appropriate operation.  In general, 25ْ C to 30ْ C (86ْ F) daily average ambient temp. is the breaking point where 100% of rating is passed.  This will, of course, be affected one way or the other depending on the combination of cooling features and the innate ability of that particular Oil Immersed Transformer to resist heating. 

Water Temperature– Water temp. should be maintained at a regular average point around 25ْ C.  An allowance is made for cooling surface deposits. 

Altitude– While altitude will affect cooling ability, higher altitudes often have lower temperatures, so they will tend to offset each other.  Altitude is not a consideration below 3,300 feet, or 1,000 meters.  Adjustment to safe operational parameters is only necessary to self cooled transformers.
