Power Quality refers to how reliable and stable electrical power is when it's delivered to homes and businesses. It's like ensuring the water coming from your tap is clean and at the right pressure, but for electricity. People who work in Power Quality focus on preventing problems like power outages, voltage fluctuations, and electrical disturbances that can damage equipment or disrupt operations. This is especially important for renewable energy sources like solar and wind power, which need to be properly integrated into the existing power grid. Power Quality professionals help ensure that electricity flows smoothly and safely, whether it's coming from traditional power plants or renewable sources.
