As a result of the Industrial Revolution, natural habitats were destroyed and the environment was polluted, causing diseases in both humans, animals, and plants.
Quick Answer. Megavolt amperes (MVA) power is a unit used for measuring apparent power. The apparent power refers to the total current and voltage in an electrical circuit. The term is preferred in descriptions of total electrical power in installations, and it captures both true and reactive power in an electrical circuit.
MVA is the aparant power, MW is the real power and, MVAR is reactive power. If you remember your Circuit II course MVA is the Square Root of MW^2+MVAR^2. Just like a right triangle. It is actually called the power triangle. You adjust the MW of a plant based on the load on the grid. Generation = Load at all times.
