In power station EPC (Engineering, Procurement, and Construction), understanding the relationship between voltage levels and frequency (Hz) is crucial for designing efficient power delivery systems. Typically, standard frequencies used globally are either 50 Hz or 60 Hz, influencing the voltage level distribution. For instance, countries operating at 50 Hz, like many in Europe, commonly use voltage levels like 220-230V for domestic power, while those using 60 Hz, like the United States, often use 110-120V. Correct matching of voltage to frequency ensures optimal performance of electrical components and machinery, reduces the risk of operational failures, and enhances safety standards across power stations.
