🔥TIPOS DE TRANSFORMADORES ELÉCTRICOS 🟢 LO QUE DEBES SABER

What Types of Electric Transformers Exist?

Introduction to Electric Transformers

• The video explores the various types of electric transformers, their differences, and their impact on industry.

• Host Fabián Raso introduces himself and invites viewers to subscribe for daily industrial electricity training.

Importance of Transformers

• A personal anecdote is shared about inspecting a large transformer (6 meters tall) to identify a fault detected through oil analysis.

• Emphasizes the critical role of transformers in substations and industries, comparing their care to that of a newborn baby.

Understanding Transformers

• Defines an electric transformer as a device that modifies voltage and current levels using two coils (primary and secondary) coupled by an iron core.

• Explains that transformers can elevate or reduce voltage without altering frequency.

Classification of Transformers

• Discusses how transformers can be classified based on:

• Number of phases: monophase, trifase, or polyphase.

• Type of insulation: dry or oil-filled.

• Application and construction type.

Types of Electric Transformers Explained

Distribution Transformers

• Distribution transformers lower electrical energy voltage for urban and rural networks; used in buildings, industries, and residential areas.

Power Transformers

• Power transformers elevate or reduce voltage at electrical substations; essential for high-power transmission systems.

Isolation Transformers

• Isolation transformers protect sensitive components by isolating high-voltage circuits; commonly used in medical equipment and telecommunications.

Current Transformers

• Current transformers convert high-intensity currents into safer proportional measurements; vital for energy monitoring systems. Important safety note: never leave secondary connections open while primary current is present.

Potential Transformers

• Potential transformers transform high voltages into safe measurement levels; utilized in protection systems.

Additional Transformer Types

Welding Transformers

• Provide necessary current for metal welding with low voltage; crucial in manufacturing industries and welding workshops.

Frequency Converters

• Operate at higher frequencies than conventional transformers; used in telecommunications, power electronics, and radio systems.

Dry-Type Transformers

• Utilize solid insulating materials instead of liquids; suitable for environments where liquid presence is restricted or safety is paramount.

Control Transformers

• Supply power to control low-power electrical equipment in industrial settings; one company reported over 3000 such units in use.

Transformers Mounted on Pedestals

Pedestal Transformadores

• These are mounted on pedestals for easy access outdoors, often found in parks or commercial areas like shopping centers.

Pole-Mounted Transformadores

• Used primarily for supplying energy to residential areas via overhead distribution systems.

Conclusion on Transformer Selection

Understanding Transformer Types and Their Applications

Overview of Transformer Types

• The choice of transformer depends on the specific needs of a system; control transformers are not suitable for powering an entire enterprise.

• Dry-type transformers are highlighted as excellent options for electrical safety, being more resistant to moisture and fire due to the absence of insulating liquids.

• Pedestal transformers are popular for outdoor applications due to their compact design, but they should not be confused with substations.

Selecting the Right Transformer

• There is no universally superior transformer; each type (monophase, triphase, dry, liquid, pedestal, pole-mounted) has its own advantages and disadvantages.

• Monophase transformers are commonly used in residential settings with one primary coil and one secondary coil, making them ideal for household appliances.

Characteristics of Triphase Transformers

• Triphase transformers are essential in industrial applications where higher power is needed; they consist of three primary coils and three secondary coils arranged to create a balanced sine wave current flow.

• To identify whether a transformer is monophase or triphase, observe the number of input/output wires: monophase has two wires each way while triphase has three.

Identifying Transformer Specifications

• Monophase transformers typically have two input and output cables along with a single core coil. In contrast, triphase models feature three cables connected to different phases.

• Checking the data plate on a transformer provides crucial information such as voltage ratings and whether it’s monophase or triphase.

Functions and Voltage Ranges of Triphase Transformers

• Triphase transformers play a critical role in efficiently distributing electrical energy by adjusting voltage levels according to application needs.

• They can handle high voltages ranging from 13.8 kV up to over 400 kV for long-distance transmission while also accommodating lower voltages like 220 V or 480 V for industrial use.

Regulatory Standards

• Voltage standards vary by country; NMXJ 098 outlines normalized voltage values that must be adhered to when selecting transformers.
