What is Dry Type Transformer?

It is a machine which consists of windings which are attached to a core, and are kept in a tank which is sealed shut and then pressurized with air.Such equipments never use any insulating medium where the winding and cores can be plunged.

Type of Dry Type Transformer:

Even though transformers are of various kinds, the dry type machine comes in two variants-

Cast Resin Dry Type Transformer ( CRT)

These devices are utilized in areas which have high degree of wetness. This is mostly because both the primary and secondary windings are enclosed in an epoxy resin. This in turn helps to a great deal since it prevents the body from getting affected or harmed with moisture. The reason why the entire the cast resin is so important is that it helps the machine in running in a glitch-free manner without causing any disruptions. This is the main reason why the transformer is non hygroscopic. Such equipments are accessible with different ratings varying from 25 KVA to 12,500 KVA. with insulation class of F (90°C Temp. Rise).

Such devices have certain advantages which are as follows:

  • Improved over load capacity.
  • Low-level partial discharge along with decreased loss. Hence efficiency is remarkable.
  • As it is with non combustible winding insulation, it offers zero jeopardy to fire hazard. So it is appropriate for indoor installation.
  • Can be fitted outdoor in IP 45 enclosure.
  • And off course non hygroscopic.
  • Vacuum Pressure Impregnated Transformer ( VPI)

Such machinery are made with the least amount of flammable elements as insulation windings. These(the windings) are fabricated using foil or strips in ceaseless layers. When we talk about high electric flux, the construction of such windings change. They are the created with disks, each of which are connected in series or parallel as per the given energy evaluation with respect to the level of electric flow. Being void free in nature, the insulation used on such goods is developed with the help of class H polyester resin. Both the cores are tied in a secure manner and are placed in a protective container which is vaccum tight. Guaranteeing you regarding their moisture resistance, such equipments come in 5 KVA to 30MVA with insulation grade F(155oC) and H(180oC). They have a protection level of around IP56. The numerous advantages of such goods are-

  • Excellent mechanical strength.
  • Void free insulation
  • No temperature alteration
  • Easy maintenance.
  • Less prone to fire risks.

Advantages of Dry Type Transformer:

The main plus points of this product are as follows-

  • Safety for users and individual property.
  • Upkeep and impurity-free solution.
  • Easy setting up process.
  • Side clearance is reduced.
  • Environmentally friendly.
  • Excellent capability to support overloads.
  • Decreased cost on civil installation works and fire protection systems.
  • Excellent execution in case of seismic events.
  • No fire hazard.
  • First-class resistivity to short circuit currents.
  • Long lasting due to decreased thermal and dielectric heating.
  • Suited for damp and contaminated areas.

Disadvantages of Dry Type Transformer:

Despite the long list of advantages, such machines have certain negative points as well. They are as follows-

  • It is highly recommended for it’s exceptional service life aspect, which low possibilities of a winding failure. But incase there is a glitch which occurs, then the whole configuration needs to be changed, which includes the in and out modification of high and low voltage windings with limbs.
  • At the same power and electric production rating, such equipment cost higher than the general oil-cooled devices of the same line.
Application of Dry Type Transformer:
  • Chemical, oil and gas industry
  • Environmentally sensitive areas (e.g. water protection areas)
  • Fire-risk areas (e.g. forests)
  • Inner-city substations
  • Indoor and underground substations
  • Renewable generation (e.g. off-shore wind turbines)
