Engineers involved in the design, manufacture, or verification of any device subjected to power disturbances or creates power disturbances, need to understand the ramifications of those disturbances to ensure a reliable, high-quality product for your customers. Products such as inverters/converters, uninterruptible power supplies, battery systems, and appliances are all susceptible to these power disturbances. These products may have to comply with a regulatory standard or a company’s own internal standard regarding power disturbances. This application note focuses on ways to measure these power disturbances, and compares using an oscilloscope versus using a power analyzer with dynamic measurement capability for measuring power disturbances.
