How to buy electrical transformers in Kenya – A complete guide

Electrical transformers are devices that transfer electrical energy from one voltage level to another. This means that they are able to step up, or increase, the voltage of an electrical signal on a given wire as well as step down, or decrease it. Furthermore, a transformer is able to do so with no loss of power and in a way that does not generate heat. As such, transformers are found in almost every home and building. An electric heater uses a special type of transformer known as an impedance transformer to convert the high-voltage AC current from the wall into low-voltage DC current to power its heating element. Similarly, transformers are used in lighting circuits to reduce household voltage and extend their range by converting 240 volt electricity into a lower voltage for use by smaller light bulbs.

Types of electrical Transformers in Kenya

Electrical transformers can be generally classified into two categories – step-up and step-down transformers. Step-up transformers are used to increase the voltage of a given electrical current. This is used to power electrical circuits that use high-voltage equipment, such as a kitchen blender, or a vacuum cleaner. Step-down transformers, on the other hand, are used to lower the voltage of a given electrical current. This is used to power low-voltage electrical circuits, like those inside a computer or a light bulb.

How to select the right transformer for your home

When selecting a transformer for your home, there are a few things you will need to consider. Firstly, you will need to know the amount of current you will be using as this will determine the amount of voltage you will need. Electrical circuits are designed to handle a specific amount of current. Selecting a transformer with a higher voltage than what is necessary will lead to the circuit overheating and possibly causing a fire. Similarly, selecting a transformer with a lower voltage than what is necessary will result in a circuit that does not perform as intended. This can lead to a drop in performance, as well as a shorter lifespan for the appliances in your home. Electrical circuits are designed to work with certain voltage levels. So, selecting a transformer with a voltage that is too high can cause these circuits to shut down or even trip the circuit breakers. Similarly, selecting a transformer with a voltage that is too low can cause these circuits to be too weak to function properly.

Step-up Transformers

– Transformer steps up the voltage from 240 volts, to 480 volts and then back down to 120 volts. – This is used for heavy-duty appliances such as hair dryers, vacuum cleaners, etc. – Step-up transformers can be used for lighting circuits, but only if all the other appliances in your home are rated for 480 volts.

Step-down Transformers

– Transformer steps down the voltage from 480 volts, to 240 volts and then back up to 120 volts. – This is used for low-voltage appliances such as computers, TVs, etc. – Step-down transformers can be used for lighting circuits, but only if all the other appliances in your home are rated for 240 volts.
