When you actually contemplate on replacing a power transformer, a few important tips could help you ensure a relatively quick return to service while reducing the future downtime and costs.
On the failure of power transformers, everything would come to a halt. This could actually put a lot of pressure on the people in charge of getting the operations back up to optimum speed. Moreover, power transformers do not go down often. Therefore, it would be a rarity for people in charge of purchasing a replacement power transformer unit to have no or little experience about the replacement process.
In addition, for people who are not often purchasing several transformers or have little knowledge about the design, transformers would be more of a commodity to them. It would be pertinent that you consider few important aspects for having long-term effects.
Need to choose the proper design of power transformer
Choosing an appropriate design and construction of power transformer would actually make a huge impact on the operating life, reduction of overall costs along with decreasing the need for future maintenance. It would be imperative to remember that quality would not always enhance the initial purchase price. However, it could largely reduce the long-term costs in several important ways.
Find below a few important aspects to counter the pitfalls in sourcing along with the installation of the remanufactured power transformer.
- Choosing the right transformer
When it comes to indoor applications, you should be choosing dry-type transformers. They have been relatively more common because of their ability to be air-cooled. It would reduce the risk of leakage, environmental, and fire issues. These could be used safely inside the facility. The dry-type units could be placed next to the powering equipment to reduce costs further.
- Assessing the winding-up decision
The method whereby the coil would be sound around the core of the dry-type transformer would affect the strength of the transformer largely. It would also affect the ability of the transformer to sustain impulses occurring from lightning strikes and switching surges. You would have the option of choosing from circular and rectangular windings.
- Considering the material
The material for windings along with insulation would affect the overall performance of the transformer largely. It would prevent emergencies from occurring during the operational life of the unit. The most common material for transformer windings would be copper, which is expensive, and aluminum, which is lower in performance and lasting strength than copper.
Your best bet would be to consult suppliers based on the specific application of the user along with present and expected power needs to choosing the right transformer.
