Fundamentals of Floating Measurements and Isolated Input Oscilloscopes, please attached file for full details.
This guide will provide you with a fundamental glossary of power measurement terms, explain the different options available for making floating measurements, and highlight the advantages and trade-offs of each option.The most demanding floating measurement requirements are found in power control circuits, such as motor controllers, uninterruptible power supplies, and industrial equipment. In such application areas, voltages and currents may be large enough to present a hazard to users and/or test equipment. When measuring floating high voltage signals there are many options to consider. Each option has its advantages and trade-offs.
