Chapter 3: Q2CSQ (page 158)

Why is it important to reduce the moisture within a transformer to acceptable levels during transformer installation?

Short Answer

Expert verified

The moisture reduces the transformer life; therefore, it is important to reduce the moisture to acceptable level.

Step by step solution

01

Moisture in the transformer.

The term moisture is used to indicate the water which absorbed by the paper or dissolved in the oil. The solid insulation majorly absorbs the moisture, but it can also be detected in the different insulation parts. The excessiveness of the moisture can be detected by water in oil analysis or dew-point analysis.

02

Importance to reduce the moisture within a transformer to acceptable level.

The moisture content is checked before the installation of the transformer because moisture helps to increase the decomposition through the oxidation of cellulose, reducing the oil's insulating property. This affects the life of the transformer and reduces the transformer's life.

Therefore, it is important to reduce the moisture within a transformer to an acceptable level.

On the base ofTa the impedance of the two components of Tbper unit. Determine the complex power in per unit transmitted to the load through each transformer. Comment on how the transformers share the real and reactive powers.

Consider the adopted per-unit system for the transformers. Specify true or false for each of the following statements:

(a) For the entire power system of concern, the value ofSbaseis not the same.

(b) The ratio of the voltage bases on either side of a transformer is selected to be the same as the ratio of the transformer voltage ratings.

(c) Per-unit impedance remains unchanged when referred from one side

of a transformer to the other.

The motorsM1and M2of Problem 3.45 have inputs of 120 MWand 60 MW, respectively, at 13.2 kV, and both operate at unity power factor. Determine the generator terminal voltage and voltage regulation of the line. Neglect transformer phase shifts.
