The choice of the power distribution transformer is an extremely important step in the business. The right decision on the unit would ensure that there was efficiency in the work, a stable system, and in the long-run, the decision would be cost-effective compared to the wrong choice, which can lead to downtime and increased spending. As a large manufacturer of transformers with a track record of driving both small-scale projects, such as Malaysian data centers, and large-scale projects, such as the photovoltaic farms, Ryan Electric is aware that the suppliers selection process should involve a balance between the technical requirements, utilization requirements as well as a balance between future-proofing. These are the guidelines that give the primary considerations.Calculate Your Load and Application Requirements
The very beginning of your decision can be put forth in the proper understanding of your application. The initial one is to calculate the aggregate kVA ( kilo- Volt- Amperes) required, which is determined by your current load requirement and your probable future load requirement also. Second, find out what voltage conversion needs do you require i.e. what voltage will you have to use at your facility as an input (primary) and what voltage will you have to use as an output (secondary)?
The application environment is also very essential. Is it a rough exterior that the transformer is placed in or in a small space like a data center or a place where fire-safety is recognized to be an important issue?
Compare Dry and Oil immersed Transformer
There are two distinct advantages of the two major technologies:
-
Dry-Type Transformers: It is insulated either by air or solid insulation (e.g. epoxy resin). They do not catch fire, are environmentally friendly (there is no possibility that they will leak oil), and are preferred as inside devices, which can be installed in commercial buildings, hospitals, and data centers. Ryan Electric has an innovative technology of developed advanced dry type and it has been able to come up with the first 110kV class three phase epoxy resin cast dry-type power transformer in China.
- Oil-Immersed Transformers: In this case, insulating oil is employed to cool the transformers and it tends to be more efficient in the higher level of voltages and power. They are all usually regarded as outdoor utility projects like 2GW Photovoltaic Project in Xinjiang where costing is the key factor in large scale.
The decision here basically influences safety precautions, laying down of installation and service plans.

Value Efficiency Review and Loss Review
Transformer efficiency directly reflects on your lifetime operating cost. Examine the total cost of ownership (TCO) and not the purchase cost. Determine the values of the transformer losses: no-load losses and load losses. A primary capital expenditure in a comparatively efficient unit like with the high international standard will bring a substantial saving in energy expenses provided that there is a lifespan of 2030 years.
Evaluate Reliability and Safety Potential
Be of top quality in terms of international and regional standards (which encompass IEC, IEEE, ANSI). Ask about the quality control, testing and design. A track record of successful deployments is a measure of reliability. The Ryan Electric supplied transformers have helped in the support of the major infrastructures as they are built in sound engineering and extensive testing processes with complete type tests on 110kV-class transformers.
Consider the Knowledge and Strength of the Manufacturer
Finally, partner with a manufacturer who does not only offer a product. Evaluate their:
Technical Knowledge and Adaptability: Are they capable of providing special solutions to special projects?
Past and Present: Request case studies of similar work done with other works as yours.
After- Sales Service: Entitle to valid access to technical service, warranty and maintenance services.
The Ryan Electric is a company that has grown since its inception in 2007 to form a joint venture with an international leader like Eaton and this is the reason why Ryan Electric would present intrinsic technical breakthroughs in the field of research and development with the capability to perform large scale and complex international tasks. We empower companies to make effective and sound resilient power systems decision making.
