what is the knee point and why it is desired that transformer operates at knee point.

Question

Accepted Answer

The knee point is the point on the magnetization curve where a small increase in voltage causes a large increase in current. It is desired that transformer operates at knee point for better voltage regulation.

Knee point is the point on the magnetization curve where the transformer core starts to saturate.
At the knee point, a small increase in voltage causes a large increase in current, which can lead to overheating and damage to the transformer.
Operating the transformer at the knee point allows for better voltage regulation and reduces the risk of damage to the transformer.
The knee point is determined by the transformer's design and the materials used in its construction.
Transformers used in power systems are designed to operate at or below the knee point to ensure reliable and efficient operation.
