| dc.description.abstract | This study presents the design and construction of a non-contact AC detector capable of identifying live conductors without physical contact. The device operates on the principle of electromagnetic induction whereby a varying electric field around an energized conductor induces a small signal in a sensing probe. The induced signal is amplified using a transistor-based circuit to activate visual and audio indicators (LED and buzzer). The detector was constructed using discrete components and tested at various distances from AC conductors within the range of 110–220 V. Experimental results showed that the device successfully detected AC voltage up to 14 cm with output voltage ranging from 0.03 V to 0.24 V from a live Ac carrying conductor demonstrating its usefulness as a low-cost safety tool for electrical maintenance. | |
