In this article, you will be learning more about the 1000kVA Transformers, its specification, and its dimensions. Generally, it transfers electrical power from one circuit to another by electromagnetic induction.
It’s used in nearly every industry, and it can be found in homes, offices, factories, and especially for a bitcoin mining power system.
And we at Daelim know how important it is for your business to have the right equipment.
Our transformers are more high-quality compared to other models on the market today.
How to Choose Dry-type Transformer And Oil-immersed Transformer?

In the actual design process of high voltage power distribution transformers, reasonable design and selection of transformers are required.
A 1000kVA transformer generally works the same as every other transformer does.
But different types of transformers vary in how they alternate current, and each has its pros and cons.
This transformer’s main factor is to step voltage up or down from the primary to the secondary windings.
Additionally, it is designed to convert alternating electrical current (AC) from one voltage to another.
Voltage step-up or down is achieved simply by adjusting the ratio of coils on one side to the other.
When voltage is introduced to the primary, it magnetizes the iron core.
A voltage is then induced in the secondary or output coil.
The change of voltage (or voltage ratio) between the primary and secondary depends on the turns ratio of the two coils.
If a transformer has 5 coils on the primary and 10 on the secondary, it will be a 1:2 step-up transformer.
A 1:2 step-up transformer means the voltage is doubled from the primary to the secondary.
If it has 10 coils on the primary and 5 coils on the secondary, it would be the opposite, a 2:1 step-down transformer, cutting the voltage in half.
When it comes to phase types, there are 2 categories.
There are single-phase types and three-phase types.
And their differences are discussed below.
Single-phase transformers commonly output and process AC power at a higher or lower voltage, which transfers energy from one circuit to one other circuit, or maybe more, through a process called electromagnetic induction.
A single-phase transformer makes use of a single-phase AC, which means the transformer depends on a voltage cycle that works in an integrated time phase.
These transformers often step down localized and long-distance transmission currents to suit residential and light commercial use.
The change in current is determined by the ratio of the primary windings to the secondary windings.
Single-phase transformers are more in-demand than three-phase in provincial areas because of their lower overall electrical demand.
Utility infrastructure and industrial regulations regulate the highest voltage on the market for a network or single-phase types.
When single-phase types are used on appliances, such as a refrigerator or computer, the lower voltage output is often sorted into direct current (DC) before powering these appliances.
On the other hand, a three-phase distribution network costs much higher and supplies power to three-phase electrical systems.
These devices are manufactured with three circuit conductors and possibly have a neutral wire.
Electric power distribution grids use three-phase type transformers to power large motors and other large loads.
Like other transformers, three-phase types are used to increase or decrease the voltage from either side of the transformer.
Variable transformers are three-phase systems that allow the user to set the desired turn ratio.
Step-up transformers can produce a secondary voltage larger than the primary voltage, while step-down transformers have a secondary voltage smaller than the primary voltage.
A three-phase circuit provides greater and efficient power density than a one-phase circuit at similar amperage while maintaining wiring size and costs lower.
In addition, three-phase power makes it more manageable to balance loads, minimize harmonic currents, and the need for large neutral wires.
Rated Power (KVA)
High Voltage (KV)
Low Voltage (V)
No-load Loss (W)
On-load Loss (W)
7.2KV – 79.57KV/
240V – 600Y/
Pad-mount transformers come in different designs. And its low-voltage winding complements the customer demand and can come in three-phase or single-phase designs.
Most pad-mount transformers are commonly oil-filled units and only be mounted outdoors.
The core and coils of these transformers are sealed in a steel tank filled with oil and include terminals for accessibility in a secure and adjacent wiring cabinet.
ANd to add to that, the wiring cabinet includes both high and low-voltage wiring compartments.
These voltages go in underground cables and pass below the terminal compartment.
In addition to those features, the wiring cabinet has sidewall doors that open sideways to reveal the wiring compartments.
1000kVA transformer specification includes fuses made of a bayonet mount fuse in a compartment with high voltage to protect itself. A high-energy backup fuse limits the electrical current in series to protect against secondary faults and overload.
Generally, single-phase and three-phase pad-mounted transformers are commonly used in underground industrial and residential power distribution, which call for safety, durability, and pleasing aesthetics.
Their enclosed build makes installing a pad-mounted transformer in public areas easier without needing protective fencing.
Pad-mount transformers are usually located on street easements and supply multiple households in residential areas.
While most typical pad-mount transformers are affixed to a concrete pad, small single-phase transformers already mounted on a base become available nowadays, making them ready for use right out away.
High-voltage winding: 95 kv.
Low-voltage winding: 30 kv.
Impedance: 5.83 %.
Electrical requirements: 60 Hz, 3 phase.
Overall 1000kVA transformer dimensions: 74 inches L x 73 inches W x 55 inches H
A toroidal transformer has a torus or donut-shaped core.
Its primary and secondary windings wind across the entire core surface divided by insulation, minimizing the magnetic flux leakage.
Toroidal transformers go best with insensitive and critical electronic circuits because of several advantages over traditional square and rectangular-shaped transformers.
They are likely seen in power supply systems, audio systems, control equipment, power inverters, and other electronic devices.
The primary component in your crypto mine will be the transformer for the mining power supply.
This transformer is commonly provided by the utility company but can be provided by the client.
They take the average voltage from a substation and convert it to low-voltage power miners.
Transformers for bitcoin mines are best deployed in 1000kVA, 2000kVA, or 5000kVA increments.
And transformers larger than this can create additional costs in the facilities switchgear and breaker panels.
It is usually cheaper to buy many 1000kVA or 2000kVA breaker panels than to manufacture a very large one.
The weight of a transformer can vary depending on the manufacturer, especially regarding the materials used to construct it.
But the average weight is 3,200 kilograms.
In a 1000 kVA transformer, the amperage equivalent is 2624.32.
Do note that the computations for different phases of transformers are not the same.
The most common transformer type in distribution networks is a step-down transformer, which converts the high grid voltage to low-voltage that Companies can use for home appliances.
