Isolation Transformers South Africa
What Are Isolation Transformers?
We use isolation transformers to transfer electrical power from AC to sensitive equipment. The transformer isolates the powered device from the primary power source for safety reasons. An isolation transformer provides isolation to prevent electric shocks.
They suppress electrical noise in sensitive connected equipment. We use them for transferring power between two unconnected circuits. We build transformers with specific insulation between the primary and secondary circuits. They can withstand high voltage between windings.
How Does a Transformer Work?
A transformer is a static electrical device. We use transformers to transfer AC current from one circuit to another circuit at stable frequencies through electromagnetic induction processes.
Voltage is decreased or increased according to the specific requirements. Transformers can step up or reduce voltage within the circuits to protect sensitive devices, such as medical devices.
What Are the Different Parts of an Isolation Transformer?
A primary winding plays a vital role in the functioning of an isolation transformer. There are many windings and additional features in transformers.
Your transformer comprises many parts. These include:
- Core
- Coils
- Oil
- Breather
- Tap changers
- Cooling tubes
- Explosion vents
- Insulating materials
- Windings
- Conservators
How Are Transformers Used for Safety Purposes?
We use transformers to determine the correct voltage between 2 systems. We link the safety needs of transformers to a series of factors. These include distance and insulation.
The design of a transformer is important. This is essential for extra protection and when determining the level of safety, the transformer needs to provide. It also determines how it handles voltage.
Why We Use Interface Transformers Specifically in Africa
Interface transformers are used on the continent of Africa. This is where conditions vary from one country to the next. Conditions also fluctuate from one site to the next.
- The Interface Transformer has an easily adjustable tap-changer. This allows for voltage fluctuations of 380VAC ~ 415VAC nominal.
- They have designed the power output for 400VAC. This is a 3-phase European standard voltage.
- 95% of all equipment manufactured in Southern Africa and Europe requires this power output.
Where Do We Use Isolation Transformers?
We use isolation transformers for a wide range of electrical devices. These include computers and industry specific electronic devices. Some include medical equipment.
For example, isolating transformers is important for oscilloscope measurement of signals in electrical circuits. This is especially important if there is no galvanic isolation from networks. The reason is the current circuit can be short-circuited between oscilloscope and grounding.
What is the Main Purpose for Using an Isolation Transformer?
The main purpose of the isolation transformer is for electrical safety reasons and for protecting electronic components. It protects persons against electrical shock.
It physically separates the power supply from primary and secondary side circuits that are connected to electronic components. They are also connected to grounded metal parts which come in contact with a person.
