An isolation transformer is a specialized electrical transformer that transfers electrical power from a source to a device while isolating the powered device from the power source. It provides galvanic isolation, preventing direct electrical connection and offering critical protection against shocks, surges, spikes, and noise.
Working Principle of an Isolation Transformer
The core principle of an isolation transformer is the physical separation of its primary and secondary windings, eliminating electrical continuity. While the input and output voltages are typically the same, the isolation helps:
This isolation enables only magnetic coupling, which ensures a safe power transfer without interference.
