Working
This circuit can be designed with CD4069 IC which includes six CMOS inverters. This chip may be used for all general inverter applications. So this circuit is used mainly for up to 1KHz frequency oscillation.
In the above circuit, R3, R4 resistors & C2 capacitors help in oscillating the IC signals which are provided to the buzzer element, so it becomes enabled when the EMF detection on testing wire and two LEDs are connected through pin 12 of the IC through BC547 transistor. So, the Q1 transistor in the circuit works as a switch & makes the first LED glow throughout EMF detection then makes the second LED glow in the EMF absence.
This broken wire detector circuit must be used with perfect 15 cm wire with spiral wire length & it works as an EMF detecting antenna. So, this circuit sensitivity can be adjusted by the VR1 variable resistor. This antenna wire should not touch a high AC supply directly, so you must be secure while AC supply testing & do not touch any supply wire with bare hands.
