Electromagnetic Induction

The core principle of transformer operation:

• Alternating current in the primary winding creates a changing magnetic field
• This field induces voltage in the secondary winding
• The number of turns in each winding determines the voltage ratio

I once explained this concept to a client using a simple demonstration. By wrapping two wires around a iron rod and connecting one to a battery with a switch, we could see how changing current in one wire induced voltage in the other. This basic principle is at the heart of all transformer operations.

Voltage Transformation

Transformers change voltage levels based on the turn ratio:

• Step-up transformer: Secondary has more turns than primary
• Step-down transformer: Primary has more turns than secondary

Here’s a simple formula to remember:

Voltage Ratio = Primary Turns / Secondary Turns = Secondary Voltage / Primary Voltage

For example, in a step-down transformer:

• Primary: 1000 turns, 11000V
• Secondary: 100 turns
• Secondary Voltage = (100/1000) * 11000V = 1100V

Heat Management

Dry type transformers must manage heat effectively:

• Core losses and copper losses generate heat
• Air circulation (natural or forced) dissipates heat
• Temperature monitoring is crucial for safe operation

During a recent industrial project, we implemented a forced-air cooling system for a large dry type transformer. This allowed us to increase its capacity without compromising on size, crucial for the space-constrained installation area.
