On March 9, 2026, the Brent crude oil price stood at 88. dollars per barrel, compared to 87. Oil prices rose slightly that week. Power Supply is 430V (P-P), 230 (P-N), 50Hz. 6 for Non Continuous Load & 1 for Continuous Load for Each Equipment. This is very helpful in determining a capacity of a power system & the required reserve capacity to meet peak loads. For example, if a residence having 6000W equipment connected has a maximum demand of 300W, than demand factor = 6000W / 3300W = 55%.
