ADVANTAGES

The electronic circuit presented here is very simple and reliable circuit for testing AC mains voltage. Although there are many AC mains voltage testers are available but the major difference between those testers and contactless AC mains voltage detector circuit is that for testing the mains voltage we have to take in contact of AC mains voltage terminal to those tester but this testing circuit can test or detect AC mains voltage without going into contact of the Voltage terminals.We need not to go in to electrical contact with the conductor carrying AC current voltage.So The main advantage of this circuit is that we donít need to remove the insulation from the conductor wire.When the conductor comes into the area of this tester it automatic tests the current or voltage.

The advantages are as follows:

q    Very simple and reliable circuit for testing AC mains voltage.

q    The circuit can test or detect AC mains voltage without going into contact of the Voltage terminals.

q    We donít need to remove the insulation from the conductor wire.
