Medium Voltage Transformers come in various sizes, but the most common type is the 2 MVA transformer.
In this guide, you will learn everything you need to know about 2 MVA transformers. Whether you’re an engineer, thinking of purchasing a couple, or just curious about these devices, read on to learn more!
With this in mind, this type of transformer is available in DAELIM’s inventory. For over 20 years, the firm has established itself as one of the leading makers of high-quality transformers. DAELIM has also followed international standards, including ANSI, IEEE, IEC, CSA, and AS/NZ.
Your transformer and other electrical equipment needs will be highly satisfied with DAELIM.
A 2 MVA transformer is electrical equipment that can transfer electrical energy from one circuit to one or more circuits. MVA stands for Mega Volt-Amp. It is equal to the product of primary current in amps and primary voltage in volts multiplied by 1,000,000.
In addition, this type of transformer is a known passive electrical device. A fluctuating current in any 2 MVA transformer’s coils could result in a varying magnetic flux.
Without a metallic link between two circuits, your company can exchange electrical energy across potentially numerous coils of this Medium Voltage Transformer. Because all electrified connection points in this transformer full load current are safely enclosed in a grounded metal casing
As a result, 2 MVA transformers can be put in locations where a fenced enclosure is impossible. In addition, your company can utilize it with underground electric power distribution cables.
Another great use of 2 MVA transformers is to scale down the line’s primary voltage to secondary lower voltage. The lower voltage is subsequently distributed to utility users. Subsequently, it makes the wind the primary electric energy transmission and conversion component.
Accordingly, several tests are done before 2 MVA transformers are released. Measuring the harmonics of the no-load current and the power consumed by the fans and oil pumps and performed. DAELIM also does dielectric experiments as well as short-circuit examination and acoustic noise level measurement. Other tests purchased components and accessories include:
The transformer saves you money on energy while also being environmentally friendly. Thanks to the integrated floor and wall mounting brackets, installation is quick and straightforward. Moreover, the offset outward facing floor installation holes provide convenient power tool access.
Most of the 2 MVA transformer specification is almost the same as other transformers. Its tank design is corrugated with flexible cooling fins. Depending on the need, it can be a pad-mounted, three-phase, or dry transformer. DAELIM uses Oil Natural Air Natural (ONAN) cooling to dissipate the heat generated by Medium Voltage Transformers.
The voltage ratio of 2 MVA transformers is 10,000 / 400 V, and an off-circuit tap changer regulates it. Moreover, it has a tapping range of +-2×2.5% with a temperature rise of 60/65 K. Additionally, the transformer has a frequency of 50 Hz and an impedance of 6.06%. All in all, the transformer weighs about 4340 kg.
Its no-load losses are at 1,680 W, and its maximum ambient temperature is 50 °C. Moreover, its ambient air temperature for operation is -20 to 50 °C for C2. Furthermore, its lighting impulse withstands voltage at 1.2/50 μs is 75 kV. Other specifications are as follows:
2 MVA transformer current rating is the value specified on the rating plate for which the current transformer is dimensioned. These values are equal to the primary and secondary currents. For most transformers, the current rating is displayed in KVA.
KVA is an abbreviation for Kilovolt-Ampere, and it is the most often used rating for transformers. It determines the size of a transformer. In many cases, the power required by the load is proportional to the transformer rating.
To know the 2 MVA transformer current rating, you need to get the primary and secondary voltage and current. The information is then put into the formula:
KVA= (V x I) / 1000
The V is either the primary or secondary voltage, and the I is the current of either of the two. For example, assume you have a single-phase transformer with secondary voltage and current of 240V and 62.5A, respectively. You’ll have 15 KVA as the current rating.
But this formula is just for single-phase 2 MVA transformers. There’s a different formula for 3-phase ones:
kVA = (√3 x V x I) / 1000
Transformer oil provides great electrical protection. The oil is also temperature stable, making it ideal for transformers. It insulates, prevents corona discharge, arcing, and dissipates the heat generated by oil-filled electrical power transformers.
The oil quantity is dependent on the max voltage of the transformer. For example, a transformer with 15 max voltage has 1,080 oil weight and 2,765 kilograms of active section weight.
DAELIM’S 2 MVA transformer is made from top-notch materials to ensure highly functional electrical equipment. The transformer has oxygen-free copper lines with lower resistivity, becoming smoother and burr-free after a series of subsequent surface treatments. Consequently, it results from a lower load loss and improved electric performance for our transformer.
It also has high-quality silicon-steel plates with decreased unit loss and lower transformer no-load.
Prime timber laminating insulation pieces that will not break or shift even when subjected to a short circuit are added.
Equally important, DAELIM has put thoroughly filtered transformer oil with less water, gas, and contaminants. The oil improves the performance of the transformers made. Correspondingly, high-quality rubber sealing materials are also in place to keep the transformers from aging or leaking.
If you’re looking for a source of power for mining Bitcoin, DAELIM’s 2 MVA transformers are perfect for the job. A more economical alternative to a considerably larger transformer as a mining power supply. 2 MVA transformers are reasonable benchmarks to follow if you want to maximize your resources.
The transformer is the ideal Bitcoin mining power system designed for commercial and household use. DAELIM’S 2 MBA transformers use aluminum or copper windings and offer adjustable voltages to maximize efficiency and reduce footprint. So, it’s a prime example of high-quality power for mining.
The copper losses in a transformer are variable losses that rely on the transformer’s current rating. On the other hand, the iron losses are voltage-dependent.
As a result, the total losses of a transformer are determined by the transformer’s voltage and current ratings. In that event, the total losses are determined solely by the volt-ampere (VA) item. It is not determined by the phase angle between voltage and current. With this in mind, the transformer rating is constantly communicated in kVA or MVA.
Volt amperes or VA are a unit of measurement used to represent electrical loads. You can also use metric prefixes like “kilo-” and “mega-.” One kilo-volt ampere equals 1,000-volt-amperes, and one mega-volt ampere equals 1,000,000 volt-amperes. As a result, 1,000-kilovolt amperes are required to produce one megavolt ampere.1 MVA equals 1000 kVA. So, 2 MVA transformer to KVA is 2000.
A dry-type transformer, especially a cast resin, has a capacity of 25 to 12,500 KVA. It has an F insulation class of 90°C temperature rise. They’re more utilized in places prone to high moisture due to the epoxy resin coating of its primary and secondary windings.
If you are looking for a transformer for underground electric power distribution, a 2 MVA transformer is the perfect option. It is made to be durable and easy to use, so you can rest assured that it will get the job done.
Finding the best 2 MVA transformers might be finding a needle in a haystack. It’s a good thing manufacturers like DAELIM are available to assist you in making your decision. DAELIM assures that all mounted transformers are manufactured of high-quality materials and meet global safety standards.
