Which part of the transformer is most affected by the operating?

Which part of transformer is most affected?

Part of the transformer which is most subject to damage from overheating is. iron core.

What affects the efficiency of a transformer?

Iron loss depends on voltage whereas copper loss depends on current. So when loading on transformer is increased means current is increased, means copper loss is increased. Iron loss is always present since charging of transformer, as copper loss increases, efficiency of transformer is increased.

What causes the primary side of a transformer to fail?

A shorted turn can easily cause enough current to break the wire, an due the cheap, high turn count winding it is easy to get a shorted turn when the insulation gets worn down by the heat. Tom. G said: Some small transformers such as these have an internal fuse or thermal overload in the primary side.

Which is the most common famous and adopted method of cooling of a power transformer?

Which is the most common, famous and adopted method of cooling of a power transformer? Explanation: Oil acts as a best coolant material, for transformer cooling. Due to its high efficiency as a coolant it is most widely used in transformers.

Which winding has more number of turns?

Which winding has more number of turns? Explanation: High voltage winding always has a large number of turns, as voltage is directly proportional to the number of turns.

At which load condition maximum efficiency of a distribution transformer will be achieved?

Explanation: Maximum efficiency for a transformer will be achieved at full load. While in the case of power factor also every device is set to get maximum efficiency at unity power factor. Thus, one will have maximum efficiency if load is nearly equal to full load and at unity power factor.

Why is transformer efficiency more than other machines?

The efficiency of transformer is greater than any other electrical machines. This is due to transformer is a static device and there is no any mechanical losses in transformers. While if you say DC machine then there is a rotational part so their losses is greater than the transformer.

What is condition for maximum efficiency of transformer?

The transformer will give the maximum efficiency when their copper loss is equal to the iron loss.

How can transformers be more efficient?

The more efficient transformers require less cooling, which in turn saves more energy. According to M Vijayakumaran, no load loss and load loss are analysed separately below. He also suggests solutions to reduce these losses, leading to enhanced efficiency of transformers. No load loss is also known as core loss.
