Power Quality
Power Quality refers to the reliability and stability of electrical power in buildings and facilities. It's like ensuring the electricity flowing through a building is clean and consistent, similar to having steady water pressure in plumbing. When power quality is poor, it can cause equipment to malfunction, fail early, or operate inefficiently. Professionals who work with power quality help prevent these issues by monitoring, testing, and fixing electrical problems before they cause damage or downtime. This is especially important in places like hospitals, data centers, or manufacturing facilities where reliable power is crucial.
