FAQ Transformers

Question: What is the difference between 1 phase transformers and 3 phase transformers.

Answer: 1. In a single-phase transformer, the electricity is supplied through two wires called Line and neutral. In three phase transformers, the electricity is supplied through three wires (four wires if neutral wire is included).
2. The voltage of single-phase transformer supply is 230V whereas three-phase transformer supply is 415V.
3. The efficiency of a three-phase transformer is significantly higher than a single-phase supply and the power transfer capability is also more.

Question: How many types of transformers?

Answer: Type of transformer can be separated by different types of applications.
1. Transformer types based on core structure.
   1.1) Iron core transformer
   1.2) Shell core transformer
   1.3) H-type core transformer
2. Transformer types based on electric system.
   2.1) Single-phase transformer
   2.2) Three-phase transformer
3. Transformer types based on voltage level.
   3.1) Step-up transformer which is use for boost voltage up then transmit to secondary side.
   3.2) Step-down transformer which is use for reducing voltage down then transmit to secondary side.
   3.3) Isolation transformer which voltage at primary and secondary side are same. Typically, applicable for Laboratory which is need stable voltage and current.

Question: What is transformer maintenance method?

Answer: 1. Should install and using in low-humidity to prevent short circuit issue.
2. Installation place should be good for heat transfer.
3. Always keep cleaning heat transfer component.
4. Always keep inspection terminal and wire.

Question: Why transformer is necessary?

Answer: Transformers is necessary because each electric device need different level of voltage. So, we must use transformer to adjust the electrical voltage from power source to sub-unit. Such as, reduce voltage from high-power electric post to the building and transformer for reduce voltage level from electric source of building to each electrical home appliance as well.
