10000 kVA Transformer: Factors to Consider Before Making Your Purchase

A 10000 kVA Transformer is an electrical device that changes voltages, typically from low voltage to high. It also changes currents, since voltage and current are related by the ohm’s law. 10000kVA Transformer use electromagnetic induction to create a winding that links two coils of wire through which an alternating electric current passes. 

This electromagnetic field can be easily changed with the flick of a switch or knob, converting a low power input into high power output, or vice versa. Transformers are used in all sorts of electronic devices including audio amplifiers and televisions – especially older ones with vacuum tubes – because they allow them to work on the mains voltage while receiving much lower power input from batteries or wall-warts (like those you plug your laptop into).

10000kVA Transformers are also used in power transmission and distribution systems. In this system, different voltage levels are used to minimize the energy loss which is inherent in any electrical or electronic device. Transformers can also increase or decrease current flow, as well as step it up or down for different uses such as for lighting or heating. Transformers allow the transmission of power from locations where generation exceeds demand to areas where generation (or storage) is less than a requirement.

If you’re in need of a high-capacity transformer to power your industrial operations, a 10000 kVA transformer may be the solution. However, purchasing a transformer of this size is a significant investment and requires careful consideration. In this article, we’ll go over some factors to consider before making your purchase.

What is 10000 kva transformer?

10000kva transformer

A 10000kVA transformer is an electrical device that transfers power from one circuit to another by electromagnetic induction. It works irrespective of the distance between the two circuits. A transformer is made up of coils of wire, usually wrapped around a steel or ferrite core.

A 10000kVA transformer provides a means for transforming voltages between two circuits without using direct physical contact. The primary coil creates an alternating electric current in the magnetic field generated by the secondary coil, producing voltage and alternating current (AC) proportional to each other.

The 10000kVA transformer does this by exploiting the mutual inductance between two coils of wire, which results from their magnetic fields interacting. Inductive coupling between the two coils can be increased or decreased, depending on how the coils are physically arranged in relation to each other and whether they are electrically connected to each other, bypassing an electric current through one or both of them. 

This allows electrical energy to be transferred between the two circuits without physically connecting them. 10000kVA Transformers are used in power distribution and voltage conversion in electronic and electrical equipment. They are used in power supplies for equipment such as electric motors, and in power plants and electric power distribution lines.

10000 kVA Transformer Specification

The load current of a transformer is measured in amperes. A 10,000 kVA transformer has a rating of 10,000 ampere-hours. This rating indicates the size and cost of the transformer. 

To determine the number of excitation transformers required for each substation, multiply the total number of degrees per phase by 2000 to find an estimate for total kVA (kilo-volt-ampere) ratings and divide them by 1000. Any excess kVA should be used to power large load centers. 

If a larger transformer is required, the alternator capacity should be increased accordingly.

The total transformer rating for all substations should not exceed 25% of the total alternator output for the entire system. A 500 kVA system contains two alternators with a rating of 250 kVA each. If these alternators are connected to a generator rated at 1000 kVA, each substation can accommodate a maximum of 250/1000 = 0.25 = 25% of the total system load or 750 kVA each.

A large transformer rating does not mean that a system will have the highest allowable voltage rating. The requirement for a high voltage to be achieved by a transformer is more complex than just multiplying the total load current by the maximum voltage rating. Large transformers are made to operate within the limits of their statistical design parameters.

The following figure is the specification of 1000 kVA x 100 % with respect to the efficiency. This specification is applicable for transformers, capacitors, and power circuit protection insulations. The transformer will be rated in kilovolt-amperes (kVA) or on a full-load basis.

A continuously operated transformer must have an initial limit frequency of at least 50 Hz and remain in compliance throughout the life of the transformer. The efficiency is measured to be 2000%.

An overvoltage protection device is required for use with this specification when it exceeds 15% at any time during operation. The device must be rated for an overvoltage of 15% and must be able to accept a short-circuit current of between 100 amps and 1,000 amps.

The initial phase conductor impedance must be 1% or greater at a frequency of 100 kHz or less. The phase conductor impedance may not exceed 1% at over 100 kHz.

The open-circuit voltage must be maintained between -150 volts and +150 volts before power is applied, but the value is not critical for this part of the specification. The voltage should also remain within the limits specified for SCR under any load condition.
