For industrial, commercial and utility applications, a single phase vs. a three phase power distribution choice is not an easy decision to make. The single phase power transformer is an essential part of certain power applications, such as lighting networks, residential feeder power lines, railway signaling, telecommunications and special equipment which are only designed to be powered on a single phase. Three phase is used for large industrial loads but single phase transformers are still vital to many other applications. Single phase power transformers are a culmination of our years of design and manufacturing perfection that provides measurable efficiencies, reliability and cost savings. Here's a list of the real power transformer advantages a quality single phase transformer has to offer an installation.
There are several facilities that require single phase power of various voltages, such as 120V, 240V and 480V. A three phase transformer bank to supply these loads can be very unbalanced, inefficient and complex. A single phase power transformer for the load profile can be used to eliminate the problems of phase imbalance and minimize the losses. The single-phase pad-mounted transformers and pole-mounted distribution transformers are made with a grain-oriented silicon steel core and high conductivity windings to provide the most efficient operation. Compact and efficient performance for single phase applications, whatever the remote or sensitive instrumentation location, is achieved by our 240 V isolation transformers and 35 kV to 240 V step down transformers.
Low complexity of one phase system flows results in low complexity reliability. This single phase power transformer has less number of winding, bushings and internal connections, which means fewer possible failure points, as compared to the three-phase transformers. This is especially true for mission critical applications like lighting on the airport, railway signals and emergency power supplies. All of the one-phase transformers, such as cast resin transformer (indoor) and oil-immersed transformer (outdoor) have been tested by full routine, type test and special test at our CNAS accredited laboratory. These are all certified to IEEE, IEC and CSA standards. The outcome is a transformer that will provide decades of trouble-free and maintenance free service – and lower total cost of ownership (TCO).
Modularity and scalability are crucial elements of any modern infrastructure project. Single Phase Power Transformer has some advantages in this aspect. For large scale distribution networks, there may be one phase transformer bank, which can be used to give a capacity increase when the size of the load changes and can be switched to a three-phase distribution network where required. The modular design will not only assist in the saving of adequate capital cost during the initial stage, but will also keep ease of handling the spares. We supply single phase pad mounted transformers of all sizes from 3.3kV to 132kV up to 10MVA as well as unit substation transformers from 3.3kV to 132kV and up to 10MVA. For tropical to desert conditions, we can change our basic dimensions, tap changer and enclosure types to meet your requirements. This flexibility allows you to easily integrate your single phase power transformer into your project, either as part of a new construction or retrofit.
There are other costs associated with buying a single phase power transformer besides the actual cost of the transformer. Apart from the price tag a single phase power transformer offers are some financial benefits as well. With reduction of the core loss and copper loss, the total consumption of energy during the transformer's working life is reduced. Furthermore, the single-phase units can be transported, handled and installed with ease because of their compact and light weight design, thus reducing transportation, handling and installation costs. A few single-phase transformers can be used in a distributed power conversion system such as a solar power farm that uses string inverters and electric vehicle charging stations to maximise land use and power system efficiencies. Each unit is produced on the full automated production lines, with a careful production process, starting from the raw material inspection, till delivery. We are UL, CE, ASTA and DEKRA certified to meet global efficiency standards with our nameplate and CNAS guarantees our nameplates. We are well known for our single-phase solutions that make a difference the first time that our clients use them and have exported to over 80 countries in the renewable energy, utilities and infrastructure sectors.
A properly designed and effective transformer will deliver real bottom line benefits to the user – improved electrical performance, tough reliability, flexibility of system integration and even substantial life-cycle savings. Our decades of experience, combined with advanced technology, and certified testing, let us create a transformer that not only meets, but exceeds expectations, ensuring that your single phase application is powered up when and where it's needed.
