Question 1

What are the main types of transformers used in industrial applications?

Accepted Answer

The main types of industrial transformers include oil-immersed, dry-type, distribution, power, special-purpose, and renewable energy transformers.

Question 2

What is the difference between a dry-type transformer and an oil-immersed transformer?

Accepted Answer

A dry-type transformer uses solid insulation materials such as epoxy resin, aramid paper, and fibreglass, while an oil-immersed transformer uses insulating oil for insulation and cooling.

Question 3

How do you select the right industrial transformer?

Accepted Answer

To select the right industrial transformer, consider factors such as required capacity, voltage, load, installation location, cooling requirements, insulation, safety standards, and efficiency.

Question 4

What is the difference between a distribution transformer and a power transformer?

Accepted Answer

A distribution transformer reduces voltage for end users, while a power transformer is designed for high-voltage, high-capacity transmission and substation applications.

Question 5

How long does an industrial transformer last?

Accepted Answer

An industrial transformer can typically last 20 to 30 years, depending on its design, operating conditions, maintenance, and other factors.
