Tips: Why using isolation transformer?

1. Generally, ungrounded systems leads to fewer single-phase electric shocks. Due to that, grounding system should be transformed into ungrounded system by using isolation transformer in some specific situation. For example, if people fix a TV which connected to an isolation transformer, he can operate it at 220V voltage with no trouble in electricity. It is safe!
2. For safety, isolation transformers are needed to supply ungrounded power to industry pick and place equipment, wave soldering machine, reflow controller, etc.
