Current transformers utilize the principle of electromagnetic induction to function effectively. These devices consist of two vital elements: primary and secondary winding. The primary winding is interconnected in series with the high-current circuit, generating a magnetic field proportional to the flowing ...
The Basics of Transformers - By raising and lowering voltage levels, transformers make power systems versatileWhen alternating current (AC) prevailed over direct current (DC) in the late 1800s, one of the deciding factors was the need for voltage levels to be raised and lowered throughout the ...
This is the second lesson of the Basic level of the Introduction to transformers course by Mr Orlando Giraldo.
In the electrical utility industry, step-up transformers revolutionized the industry by allowing energy — higher voltage and lower current — to be transmitted from remote electrical generating plants over great distances. The higher voltage reduces size and cost of transmission lines and reduces transm...
Transformer types are main transformer, audio frequency transformer and radio frequency transformer. Main transformers are used in Britain, which works at 50 Hz and primary voltage of 240V AC. The secondary windings may be step up or step down or will have one or more of each. ...
These relationship described above can be used to calculate each of the parameters in the equation. The formula above is known as thetransformers voltage action. Since we said the power remains the same after transformation then; This formula above is referred to as thetransformer's current action...

Transformers come in range of sizes from a thumbnail- sized coupling transformer hidden inside a stage microphone to huge giga VA-rated units used to interconnect portions of national power grids. All operate with the same basic principles and with many similarities in their parts, though a ...
