How 1500 kVA Pad-Mounted Transformer Works for Bitcoin Mining?

Bitcoin mining is the process of assembling the latest transactions, from about 10 minutes ago to become permanent in the history of chained transactions.

And the 1500 kVA Pad-Mounted Transformer can help you with just that.

When the accumulated transactions are compiled and added to the history, those who devoted computer resources to achieve it are rewarded – this happens every 10 minutes or so – putting more bitcoins in circulation.

A transformer is the first component in your crypto mine, usually provided by the utility company and possibly the client.

The transformers take the medium voltage, convert it to a usable low voltage from a substation, and use it as a mining power supply.

Larger transformers can create even more costs in the facility’s breaker panels and switchgear.

Multiple 1000kVA or 2000kVA breaker panels are usually cheaper to buy than to manufacture one large one.

Transformers for crypto mines are observed to be best deployed in 1000kVA, 2000kVA, or 2500kVA increments. Making the 1500 kVA Transformer a good midpoint.

What Is The Usual 1500 kVA Pad-Mounted Transformer Load Capacity?

The 1500 kVA Transformer load capacity is usually at 2,880 watts for no-load losses and 15,700 watts for Full-load losses. Making the total losses 18,580 watts and granting a maximum efficiency of 99.11 at 42.83% Load.

Generally, the windings’ average temperature rise will be around 55 to 65 degrees Celsius when the transformer is set to provide the rated kVA output in a 40 degrees environment. It is measured by the resistance method.
It can operate at least 30 degrees Celcius and 40 degrees max ambient without reducing service life expectancy. A 1500 kVA Transformer withstands a maximum temperature rise of 150 degrees Celsius above a 40°C maximum ambient.

Dry-type transformers are mounted in a heavy gauge steel enclosure which consists of these three isolated sections on a common base to form an integral load center:

  • High voltage compartment
  • Low voltage compartment
  • Transformer compartment

Indoor enclosures with weather shields are not allowed because the enclosure is constructed as NEMA Type 3R rated for rain resistance.

What Are Common 1500 kVA Transformer Specifications for Bitcoin Mining?

Transformer specifications can vary depending on the manufacturer. But there are 4 major specifications you need to consider. These are Primary voltage, Secondary voltage, Power Rating, and Enclosure Type.

Primary voltage is the input voltage of a transformer. Referring to the voltage applied to the terminals of a transformer’s primary winding, the energy applied to the primary must be a changing voltage since only a changing magnetic field will produce a current in the secondary.

In contrast to the primary is the Secondary voltage. This is the output voltage of the transformer and the voltage that will sustain your crypto farm power.

Power Rating is the total power for mining that the transformer provides. Expressed Kilo volt-amps or kVA and is calculated with the following formula: S(VA) = I(A) × V(V)

This means Single Phase Amps (S) to volt-amp circulations (VA) is equal to Current (I) in amps (A) multiplied by the voltage (V) in Volts(V).

And lastly, Enclosure type. This specification pertains to the type of casing used to manufacture the transformer. Depending on the condition you want your transformer to be exposed to, it can vary from NEMA 1, 3, 3R, 3RX,4, 4X, and 12.

And here are a few other specifications and features:

  • High and Low-voltage Load Switch
  • Oil-immersed (Level Gauge and Oil Drain Valve)
  • Plug-in Protective Fuses
  • Cooper or Aluminum Winding Conductor
  • Thermometer
  • Automatic Pressure Relief Valves
  • Heat Sink
  • Power frequency: 60Hz
  • Impedance 5.59

What Are 1500 kVA Transformer Dimensions For Bitcoin Mining?

The typical overall 1500 kVA Transformer dimensions stand at 82 inches tall, 82 inches wide, and 83 inches in depth.

It weighs 9,888 pounds and typically holds up to 368 gallons of oil.

How Small Substation Transformers Work For Bitcoin Mining?

Substation transformers are a collection of transformers and switchgear that route the power to residential and commercial buildings. 

They are mounted indoors or outdoors on a concrete pad with high and low-voltage cables. 

These transformers are also designed for installation on three-phase transmission and distribution systems.

The liquid-filled substation transformers have various industrial and utility applications.

These transformers often include one of 2 different fluids. Either Mineral oil or silicone transformer oil.

Primary voltages of a substation transformer usually range from 2.4 kV to 69 kV in 225 through 20,000 kVA sizes but are also available for 600 volts through 35 kV secondary voltage ratings.

What Are Common Small Substation Transformer Specifications for Bitcoin Mining?

There are more than a few reasons why a transformer needs to be operated underground. Like space limitations, safety restrictions, or quality requirements.

With that in mind, you will need these critical components and utilities to develop your crypto mine further:

  • Main Transformer
  • Circuit Breaker Panels
  • Power Distribution Unit (PDU)
  • Control and Monitoring Software

Your main transformer will be the starting point of your whole power system, which converts high-voltage to low-voltage.

And following that would be the main disconnect.

The main disconnect is a switch used to cut all power for maintenance or in an emergency.

A circuit breaker panel is connected to the main disconnect, where the power is distributed out to the power distribution unit.

While selecting the type of panel to use, it is also good to consider the circuit breaker to install.

There are a few more things that factor into this, like the enclosure type, wiring or bus bar, circuit breaker sizing, and power system poles.

Next is your power distribution units, the final line of defense against power surges, spikes, and the like.

Selecting PDUs drives changes through your whole crypto farm.

On top of that, there are many things to consider when it comes to your PDU, Like enclosure size.

The 2 types of commonly used enclosures for crypto are vertical mounts and horizontal rack mounts.

Vertical mounts, despite their name, are typically mounted horizontally to run across long shelving racks and take up the least amount of space while providing better spread outlets.

Horizontal mounts are more popularly used for server racks and do not work well in cryptocurrency.

Other factors involved with PDUs are power configuration, safety precautions, and outlet types.

What Are Small Substation Transformer Dimensions For Bitcoin Mining?

In terms of dimension, substation transformers pretty much share the same details as the 1500 kVA Transformer.

And there are different dimensions and weights for these transformers, which also vary depending on the rise. But the approximate 1500 kVA transformers dimensions are:

  • Height: 90 inches
  • Width: 90 inches
  • Depth: 58 inches
  • Weight: 8,810 pounds


When in doubt, you can consider getting a mini substation that only requires a small amount of space if you have concerns with the location of your mining area and power consumption.

Do keep in mind that mini substations and regular substations have a significant difference in rating.

And if you are looking to customize a mini substation for yourself, consider contacting DAELIM for any advice and recommendations you want to look for.
