Where to Buy Power Transformers in Nigeria
Power Transformer is an electrical apparatus designed to convert alternating current from one voltage to another. It can be designed to “step up” or “step down” voltages and works on the magnetic induction principle.
Our Power transformers have no moving parts and are completely static solid state devices which ensures under normal operating conditions, a long and trouble-free life. It consists in its simplest form of two or more coils of insulated wire wound on a laminated steel core. When voltage is introduced to one coil called the primary, it magnetizes the iron core. A voltage is then induced in the other coil called 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.
Power Transformers are widely used also for stepping up and stepping down the voltage at the electrical power generating station and distribution station (or substation) respectively.
There are several reasons for using a power transformer in electrical power systems. But one of the most important and simple reasons for using the power transformer is to reduce power losses during electric power transmission.

Applications of Power Transformers
The power transformer is mainly used in electric power generation and at distribution stations.
It is also used in Isolation transformers, earthing transformers, six pulse and twelve Pulse rectifier transformers, solar PV farm transformers, wind farm transformers and in Korndörfer autotransformer starter.
It is used for reducing power losses during electric power transmission.
It is used for high voltage step-up and high voltage step-down.
It is preferred during long-distance consumer cases and preferred in cases where load runs at full capacity 24x7.
Frequently Asked Questions (FAQ) about Power Transformers
Can a single phase Power transformer be used on a three phase source?
Any single phase Power transformer can be used on a three phase source by connecting the primary leads to any two wires of a three phase system, regardless of whether the source is three phase 3-wire or three phase 4-wire. The transformer output will be single phase.
What is the difference between a power transformer and an instrument transformer?
A power transformer is used either for stepping up or stepping down a voltage level, primarily in power transmission and distribution. An instrument transformer is used in a circuit for the measurement of voltage or current. Current transformers and potential transformers are examples of instrument transformers.
Why do Power transformers hum?
Power transformer hum or transformer noise is caused due to the repeated expansion and contraction of the steel core inside the transformer. The expansion of the core depends on the amount of flux, which in turn depends on the applied voltage and number of turns of transformer coils. The magnetic flux passing through the transformer core varies continuously which expands and contracts the core.
What is the purpose of Transformer oil?
Our Transformer oil functions as a coolant as well as insulating material. It also enables transformer protection during internal faults. It is chemically stable and has high thermal conductivity and dielectric strength. On the event of faults it decays rapidly and forms gases which operate Buchholz relay.
Can a Power transformer be connected reversely?
Yes, a power transformer can be connected reversely. However, the output voltage will be less than the rated voltage due to the compensation factor of the windings.
Power Transformer being the vital and essential device in the electric network has gained the maximum importance. Flow of power and electricity into our homes and other locations would not be possible without the availability of power transformers.
Power transformers are designed to handle high voltage inputs and can operate at 100% efficiency. Typical power transformers can handle high voltages in the range of 33 to 400 kV. Moreover, power transformers use the disc-type of winding, which connects separate disc windings in a series through outer and inner crossovers.
