Abstract: A relay welding detector (72) is adapted for detecting welding fault of a relay (71). The relay (71) has a first electrical contact (711) coupled to a neutral terminal (N) of an alternating current (AC) power source (6) through a first power line (91), and a second electrical contact (712) coupled to a load (8) through a second power line (92). The relay welding detector (72) includes a signal generator (721) generating a test signal, a current transformer (722) wound with a portion of one of the power lines (91, 92) and generating an induced signal based on the test signal, and a determining unit (723) determining, based on the induced signal, whether the electrical contacts (711, 712) of the relay (71) are welded to each other.
