The whole circuit can be accommodated in a small PVC pipe and used as a handy broken-wire detector. turn on switch S1 and slowly move the test probe closer. INVISIBLE BROKEN WIRE DETECTOR. IN HOUSE TRAINING PROJECT. 1. ABSTRACT. In our day to day life we use various electronic appliances employing. 3 Aug A continuity tester is a device which tests the continuity of the wire at hand. It is an indispensable tool to check broken wires and undesired.

Portable loads such as video cameras, halogen flood lights, electrical irons, hand drillers, grinders, and cutters are powered by connecting long 2- or 3-core cables to the mains plug. More information about text formats. A 3V DC supply is sufficient for powering the whole circuit.

invisible broken wire detector Published by Mercedes Poyser Modified over 3 years ago. It detects the broken wire by detecting the presence of AC voltage in the wire. Invisible broken wire detector of this Broken Wire Detector is very easy and the main part of this circuit, as mentioned preciously, is a hex inverter IC CD Gates N1 and N2 are used to sense the presence of V AC field around the live wire and buffer weak AC voltage picked from brroken test probe.
And because of this, people generally prefer to replace the broken instead of repairing it.
In 3-core cables, it appears almost impossible to detect a broken invisible broken wire detector and the point of break without physically disturbing all the three wires that are concealed in a PVC jacket. Similarly, the low output of the pin 6 restrain the transistor from conducting.
Uttamraj Giri December 22, at 5: The circuit is made cheap and best. Leave this field blank. Your Projects that you have made open to all of us will be very helpful When the circuit detects the presence of AC voltage near it, then the output pin 10 goes high. I definitely enjoyed every little bit of it and I have you bookmarked to check out the new stuff you post.
It would not only be able to Reduce wastage of time but also resources Thus using just a hex inverter and few resistors we are able to construct a device which can easily detect a faulty broken wire and invisible broken wire detector save invisible broken wire detector extra cost of user which is incurred on replacing the faulty wire and not repairing it which is difficult.

We can use an inverter in between the led and the oscillator which will then turn on the LED only when the broken point is detected and keeping it off when wire is not broken.
In 3-core cables, it appears almost impossible to detect a broken wire and the point of break without physically disturbing all the three wires that are concealed in a PVC jacket.
It is very difficult to locate the accurate location of the broken wire, because now days electric wires are installed inside the walls by using the PVC pipes. Posted by Uttamraj Giri at invisible broken wire detector We think invisible broken wire detector have liked this presentation.
That point is the location of breakage. As a result LED 1 goes off. How much range it will cover. The main part of the project is IC Invlsible Pravin October 18, at Thus during every positive half cycle of mains frequency N2 goees high,and oscillator circuit is allowed to oscillate at around kHz making LED 1 to blink. Thus the circuit was made successfully which ingisible easily detect broken point in the invisible broken wire detector inside PVC jacket without physically disturbing it.
Gates N3 and N4 are used as a pulse generator that oscillates at around Hz in audio range. Invisible broken wire detector type of blinking reduces consumption of the current from button cells used for power supply. Our basic aim in this project is to locate the exact position of breakage in conducting wires concealed in PVC jacket without physically damaging the jacket thus reducing the waste of time as well as resources.
