Why silicon gel used in transformer?

Silicone gel is used in transformers as a cooling and insulating material. It helps to dissipate heat generated during operation and provide better insulation to prevent short circuits. Additionally, silicone gel is non-toxic, non-flammable, and has good resistance to moisture, making it a reliable choice for transformer applications.


Why dew point measurement is necessary in nitrogen filled transformer?

Short Answer: Dew point measurement is necessary to ensure the moisture content of the cellulose insulation is low enough to safely energize the transformer (after filling with oil). Maximum acceptable moisture content varies with unit size/age, but less than 1% moisture content is generally acceptable.


What effect does the waste energy from a transformer have on the air around the?

The waste energy from a transformer can increase the temperature of the air around it due to heat dissipation. This can lead to a localized warming effect, which may impact the immediate surroundings by potentially altering air currents or affecting nearby equipment or structures. Additionally, the waste energy may also contribute to overall energy loss and reduced efficiency of the transformer system.


What is mean core saturation?

Core saturation occurs in electrical transformers when the magnetic flux in the core reaches its maximum limit, resulting in a decrease in efficiency and potential overheating. It can be caused by excessive current or voltage in the transformer, leading to distortion in the output waveform and potential damage to the transformer.


How you can find positive and negative in a transformer?

There is no positive and negative on a transformer. Transformers will only pass AC (alternating current), due to the fact that induction will only occur with a moving field. The current has to be changing polarity and intensity continuosly, for the current to be induced in the windings. Both terminals on the output vary, with relation to each other. Put DC into a transformer and the coils will saturate, overheat and probably burn out.
