How You Can Determine The Best Transformer Selection For Your Place?


   Let’s find out which one- dry type transformer or liquid cooled transformer is better and why
Transformer is a device that requires power electricity to perform operations. It transforms power between circuits with changed voltage and current values and at same frequency. Manufacturers in India are producing extensive range of transformers, the three major designs that are in huge demand are- dry type transformers (in this, air is used as a dielectric and cooling medium). They are also supplying transformers spares to major clients on special request across the globe.

Most manufacturing foundries produce and intend dry types with vacuum pressure impregnation in silicone varnish or polyester), liquid filled transformers (fluid is a cooling and dielectric media that remains in a liquid form while operating the transformer), and liquid vapor condensation type transformer (in such transformers, coils and core are immersed in a low boiling fluid that takes transformer heat away and evaporates and then returns in liquid form via condensation inside the radiator tubes).

No doubt the technology has surpassed and major innovations are introduced to transformer industry. What was considered to be the suitable coolant became an environmental disaster and we have been reading stories on retrofits and alternatives to PCB filled transformers. There are now three significant alternatives to PCB filled transformers – mineral oil, dry type transformer, and silicone.

Which Transformer Suits Best - Dry Type Transformer Or Liquid Cooled Transformer?
Here we got few considerations for selecting a transformer, these are:
  1. Fire Risks - Transformers are placed in habitable or covered areas, like buildings that are constructed with fire fighting strategies or where fire risk has to be minimized. Moreover, fire risks in chemicals or mining pressurize users to install non-flammable or self-extinguishing equipments to minimize the fire risk.
  2. Environmental, Health and Safety Concerns - When making a selection between transformers, it is important to ensure that the model uses environmental friendly and biodegradable materials. Dry type transformers are worth buying because these models use air as a coolant and so, there is no risk of leakage, water or ground contamination.
  3. Installation Cost - Engineers find dry type transformers easy to install unlike liquid filled models as there are no radiator banks present in the dry transformer. These models are easy to install, near to electrical load, which lowers the length of cabling requirement.
  4. Maintenance Costs - Dry type transformers do not use any liquid coolant that could create leakage trouble and thus, there is no such heavy maintenance requirement for these transformers.
So, it’s clear. Dry type transformer fits in most situations and can be considered over liquid filled models. To find reliable spares and dry type transformers India, use online directories, official websites contact info and references of leading transformer manufacturing companies in India.
