ABSTRACT:
A phase sampling protection device substantially includes a phase sampling circuit coupled between a tube circuit and a protection circuit. The phase sampling circuit captures a voltage signal and a current phase signal of the tube circuit for comparison, using phase comparing technique to detect an anomaly of the tube, if the tube doesn't function normally, then the phase sampling circuit driving the protection circuit to shut down the power supply of the tube to keep a transformer from burning down and other safety issues from happening.
