ELECTRIC, WITH AN EDGE
400 kVa transformers preserve electrical energy as it travels from the primary distribution network to a secondary distribution consumer. This type of transformer reduces the voltage of the primary component while diverting electricity to a secondary distribution case. And the 400 kVa transformer price is the most affordable and common type.
DAELIM has been considered the best transformer manufacturer with 15 years of experience and development. Moreover, DAELIM’s multiple standards, cutting-edge service, and speed in professional customization skills made their clients continue to trust them.
DAELIM customers may tell them how many transformers they need and their primary and secondary voltages and give them the best 400 kVa transformer price and delivery estimate.
The standard price of a 400 kVa transformer ranges from USD 30,000 to USD 70,000. The going rate for dry-type 400 kVa transformers is about USD 5800. Therefore, the final cost is still determined by the needs of individual buyers.
The user can reap numerous benefits aside from the 400 kVa transformer price. For instance, Aluminum transformer winding material that has been precisely trimmed is one way to boost efficiency. The tight manufacturing tolerances mean there are no performance-reducing burrs.
Each core has a moisture-resistant coating and is electrically balanced to reduce axial stresses in the event of a short circuit. In particular, the 400 kVa immersed transformer is exceptionally quiet, resistant to short circuits, lightning-proof, and long-lasting.
In addition to giving environmental benefits, this transformer offers its owners substantial energy savings. The machine’s energy efficiency can reach 99.44%, and it can run reliably and without interruption 24 hours a day, seven days a week. Transformers with greater efficiency last longer and save their owners money on energy and overall maintenance fees.
Floor and wall mounting brackets are built in, and the holes in the floor are offset to the side so that power tools may be easily accessed during installation. The transformer is built to last and withstand heavy impacts because it comprises high-quality, eco-friendly materials.
Some 400 kVa transformer specifications include efficiency, safety, and being built with concern for the natural world. The 400 kVa transformer can be used indoors or outdoors and protects against the breakdown of essential machinery.
This transformer is great for various uses and enterprises due to its low running costs, reduced heat emissions, and low cost of ownership. In addition, below are some of the 400 kVa transformer specifications.
●Oil Filling with the Oil Impregnation process
●Mineral Oil or Silicone Oil or as needed
●Low Power Loss
●Electrolytic Grade Copper winding
●Built for system supply variations and ambient temperature
●Consists of step lap construction & mitered joints for core
●Losses as per star rating as per BEE
●Low-loss CRGO Silicon steel for core
●Low Noise
Customers should carefully analyze the 400 kVa transformer’s weight before purchasing. The transformer’s weight is typically broken down into two categories: the total weight and the oil weight. Oil-immersed transformers are typically substantially heavier than dry-type transformers of the same rated capacity.
400 kVa transformer weight is often less than 2000kg, and the oil weight is typically less than 500kg. In contrast, dry-type transformers often weigh no more than 700 kilograms. And the precise amount of weight depends on what the market demands. The duty is now on transformer makers to reduce their weight without sacrificing performance or efficiency.
The dimensions may differ depending on the type of transformer. Not only do large and low voltage impact transformer sizes but so do rating capabilities. Typical 400 kVa transformer dimensions for oil-immersed types are 2000mm (width) x 1500mm (height) x 1600mm (depth).
The common 400 kVa transformer dimensions for a dry-type are between a thousand and a thousand, a millimeter wide, and a millimeter or two in height. However, the exact measurements still depend on the target audience’s preferences.
There is a wide variation in oil capacity amongst transformer designs. An oil-immersed distribution transformer of 400 kilowatts of power typically has a capacity of less than 700 kg of oil. Yet, a dry-type transformer doesn’t require any discussion of oil capacity.
The installation process starts with supplying 400 kVa, transportation to the site, plinth installation, testing, and commissioning. After that, dismantling of the existing transformer is next. Then, the power cables will be supplied and laid underground with 3.4 x 400 sqmm both ways. Followed by the cable glanding, termination, and earthing.
With that, the supply and laying of earthing conductors of copper flats are next in the process. In addition, fabrication, supply, and fixing of mild steel racks, trays, ladders, and such will also occur. Then proceed on the supply and fixing of lightning arrestors for the transformer, the HT, and the LT danger board.
After those steps, the current gang-operated overhead air break switch will be repaired. For the twelfth step, earthwork excavation for cable trenches and laying bricks in those trenches occurs after cables are laid and covered with fine soil. Then for the last step, the calibration of relays for the 400 kVa transformer incomer feeder in MSB.
An essential part of any distribution system is the 400 kVa distribution transformer. Short-circuit currents can cause failures during operation, such as low-voltage outlet short-circuits, which can substantially compromise the equipment’s stability and potentially induce safety concerns. And this may raise a significant threat to the integrity of the apparatus and can cause safety incidents.
The deformation of a typical 400 kVa distribution transformer winding caused by a short circuit shock to an outlet is examined. A thorough diagnostic analysis and test findings from a crane inspection are used to determine the issue’s nature and the risk’s severity.
And to gather information and experience in fault diagnosis for the safe operation of future equipment, specific solutions were proposed to increase the operational reliability of the 400 kVa distribution transformer in the case of an outlet short circuit failure.
Aside from the affordable 400 kVa transformer price, there is a 700-watt core loss and a 2800-watt full-load copper loss in a 400-kilovolt-ampere (kVa) transformer. At the unity power factor, the transformer operates at 99.30% efficiency.
Another crucial characteristic of transformers is their impedance. The transformer’s impedance is a crucial parameter, typically expressed in percent. The factory does a short circuit test to determine the impedance. To short-circuit current, this is of crucial importance. The transformer’s specifications define both impedance and loss. Impedance is typically around 4% for a 400 kVa transformer.
First, determine what A transformer’s load capacity specifies the maximum amperes it can safely handle. Finding out the transformer’s load capacity will tell you if it’s an appropriate size.
Knowing whether the transformer is single-phase or three-phase and the line voltage of the secondary output is necessary for determining the load capacity. Calculate secondary voltage using the formula: secondary voltage = kVa * 1000. With this knowledge in hand, you may move forward. The following formula can determine a transformer’s rating: P=√3*V*I.
And there you have the 400 kVa transformer price and its basics. If you are looking for a suitable transformer specialized for oil mines, factories, and workshops, a 400 kVa transformer is the best choice. And to ensure its quality, DAELIM can offer both affordable yet high-quality transformer that has stood the test of time.
