A couple purposes for using an isolation transformer: 1. It blocks any DC on the AC power line from getting into your components' power transformers which will affect their magnetic behavior with possible saturation. 2. The very low capacitance type do a good job of filtering high frequency noise on the AC mains from entering your components. Used with sensitive electronic components such as computers, audio systems...etc This would be great if you have to power off of a stand alone generator...
