Best Non-contact Voltage Tester 2018


The best non-contact voltage tester 2018 can change your working mind by its new features. it is the best ever made non-contact voltage tester in 2018.

Non-contact voltage tester is the secure way to check the electrical power without touching any wires. The non-contact voltage tester comes in handy. the tester will light up when it comes to close to a live electrical wire, even one that’s covered in plastic insulation. The non-contact voltage tester can not test voltage through a metal conduit or metal sheathing.
Before using the tester just simply check the batteries an easy way by putting the tester tip into a live electrical socket. You will see that a series of indicator or LED’s are flashes to confirm the tester has detected voltage.

The necessity of Non-Contact Voltage Tester
A non-contact voltage tester is a life-saving device for an electrician or a person. Whatever you are, making a simple electrical repair in your house. It’s a device that sometimes separates you from life from death. The tester can detect voltage without touching the wire and show an indication that a wire or an object is carrying electrical current.

How does Non-Contact Voltage Tester Work?
The non-contact voltage tester work on a simple physical phenomenon. You already studied back in school that “A CURRENT CARRYING CONDUCTOR CREATES A MAGNETIC FIELD AROUND IT” There is a sensor inside the tester that interacts with the present magnetic field around the live wire and provides an indication whether or not voltage is present or not. The tester sensor indicates voltage even the conductor is under several layers of insulation.

Do you Need the tester in Your House?
Doesn’t matter you have an interest in electrical work or not but this type of tools may always you should have. These handy tools help you to replace a faulty electronics or replacing damage switches. If you are in a new home, it can help you to map your circuit box if it is not labeled.

 The Possible Applications of the voltage tester:
There are a lot of places where you can find the use of the non-contact voltage testers. Some of the most common use is given below.

⇒Testing switches and receptacle:
The non-contact voltage tester is very useful. If you want to check the wall socket or switch, just put into the testers tip in the socket and you will know the voltage is available or not.

⇒Replacing Switches:
The tester will help you to confirm that you have turned off the right circuit breaker if your circuit breaker box is not mapped correctly. So it will help you to avoid an electrical accident.

⇒Fixing open end wires:
Let suppose that you came across an open end wire in your house. Before you start to fix that cable, the tester will get confirmation that whether the electrical power is flowing through the cable or not.

⇒Troubleshooting power strip:
Sometimes in home power strips or outlet are not working correctly and you have to check the strips or outlets. Before you start to check outlets you can check the strips or outlets are receiving electrical power in the first level or not.

⇒Patching broken wire:
Sometimes wires are comes twisted together to minimize interference with devices. So if the power cable breaks internally, it is so difficult to locate fault by conventional detectors but non-contact voltage detector can easily detect fault just by running the tester over the cable.

There are many other uses of Non-Contact Voltage Tester. Which we will be discussing at some other point in time.
