Advantages and Disadvantages of 60 Hz (US) and 50 Hz (EU) Frequency

More power transmission: 60 Hz power can transmit more power over longer distances with less loss.
Better efficiency: Some types of equipment like motors and transformers can be more efficient at 60 Hz.
Common frequency standard: 60 Hz is a common frequency standard in North America and parts of South America, allowing for easier interconnection and coordination of power systems across regions.

Equipment compatibility: Some types of electronic equipment may be designed to operate at a frequency of 50 Hz, so they may not function as efficiently or effectively when used in regions that use 60 Hz power.
Higher voltage levels: Due to the higher frequency, the voltage levels of 60 Hz power are also higher, which can be a safety concern in some situations.
Increased skin effect: At higher frequencies, the skin effect becomes more pronounced, causing current to flow primarily on the surface of the conductor, which can increase resistance and reduce efficiency.

Stability and precision: 50 Hz power can be more stable and precise for certain applications, such as in timing and synchronization systems.
Compatibility with electronic equipment: Some types of electronic equipment may be designed to operate at a frequency of 50 Hz, so they may function more efficiently or effectively in regions that use 50 Hz power.
Lower voltage levels: Due to the lower frequency, the voltage levels of 50 Hz power are also lower, which can be beneficial in some situations.

Power transmission efficiency: Due to higher reactance, 50 Hz power may result in higher power loss during transmission over long distances.
Equipment efficiency: Some types of equipment, such as motors and transformers, may be less efficient at 50 Hz due to higher core loss and magnetizing current.
Incompatibility with some standards: 50 Hz is not a common frequency standard worldwide, which can create challenges for international interconnection and coordination of power systems.
