The weight of a 115kV transformer can vary depending on its size and design, but typically ranges from 5,000 to 50,000 pounds.

The oil should be greater than 100M Ohms resistance. If a flash over occurs within the transformer the oil has to be replaced
A step-up transformer increases voltage, while a step-down transformer decreases voltage.
When the frequency of a transformer is increased, the core losses of the transformer increase due to increased eddy current losses and hysteresis losses. This results in a rise in temperature of the transformer. Additionally, higher frequency can affect the impedance of the transformer and alter the voltage regulation and efficiency.
A step-up transformer increases voltage, while a step-down transformer decreases voltage.
The footprint of a transformer foundation depends on the size and weight of the transformer, as well as the specific design requirements to support and securely hold the transformer in place. Typically, the foundation will be sized to provide adequate support and stability for the transformer, as well as to distribute the weight evenly across the ground to prevent sinking or shifting.
In general, the lower the frequency of operation, the more weight must be added to the core laminations to avoid magnetic field saturation. This increases the size and weight of the transformer as the frequency decreases.
Look at it and find its weight. If it is heavy it contains a transformer and is dimmable. If it is very light and obviously contains no transformer, it can't be dimmed.

The transformer used in mobile is pulse transformer which operates at very high frequency pulsating DC in order to make charger energy efficient and light weight.
The most important trends in coil and transformer production were continued miniaturization and weight reduction, as well as surface mounting
no transformer is not necessary for rectification today most of power supplies have been made without using transformer in order to reduce weight and size of power supply.for example SMPS(switch mode poqwer supply)
The weight of 1 litre of transformer oil can vary depending on its specific gravity, which typically ranges from 0.84 to 0.89. To convert volume to weight, you can use the formula: weight = volume x specific gravity. Therefore, for transformer oil with a specific gravity of 0.84, the weight of 1 litre would be approximately 0.84 kg, and for oil with a specific gravity of 0.89, it would be around 0.89 kg.
Due to the heavy coils found inside the body also you will find an insulation that is oil type, that s why it s so heavy , but if u look at the dry type transformer u will find it so light and compact that s all i know my sir Eng: Amr <<>> The reason that power transformers are so heavy is from the steel laminations that the core of the transformer is built from. The outside transformer is constructed out of steel which also adds to the weight. Transformer coils these days are using aluminium wire for the primary and secondary wraps. This keeps the weight down and also helps in preventing copper theft.
