Voltage Testers

A voltage tester is an electronic equipment that tests the presence of electricity in a circuit or equipment. However, there is a wide range of testing options available in the market. They may range from simple test lights to digital and even non-contact options. Let us explore which ones work best for your application.

The basic voltage tester comes in the form of a test light. It contains a tiny neon bulb and two insulated wires attached to it. Electricians use this tester to determine whether the current is flowing through the wire or not. It also lets you know if an adequate voltage is there in the wire or not. By attaching the flying lead to an earth reference and touching the tips of the tester to different points in the circuit, you will be able to detect the presence of voltage at those points. However, many other types of testers are also there, which may work differently. If you are planning to buy a voltage tester online in the UAE, then you have reached the right place. The below guide will help you choose the best.

Things to know about voltage testers & their types

For the projects like replacing an outlet, installing wiring, or putting in new lights, you need to follow some safety measures. Whether you are a DIY person or a professional, a voltage tester is a must-have for your kit. It not only helps you test receptacles & switches for current flow but also helps you fix open-end wires. Moreover, sometimes the power outlets do not work properly. But if you have a tester in your kit, you will be able to check the power before fixing the issue. The best part is that they come in a wide range of options based on the type of application. To make the most out of this excellent device, you should be aware of its popular and useful types. So, read on!

One-contact vs non-contact voltage tester

As the name suggests, with the one-contact tester, only one side of the under investigation circuit is contacted. The tester depends on your body to behave as earth and complete the circuit. However, it sometimes involves the risks of short-circuiting faults or shocks. On the other hand, with a non-contact one, you do not have to come in contact with the live circuit. It is a device that can detect changes in the electrical field when brought near. Using the best non-contact voltage tester is one of the safest and easiest ways to ensure that electrical conductors have power or not. When you place it near a live conductor, the electrostatic or magnetic fields induce a current flow through the tester.

Voltage detectors & their types

Voltage detectors determine the presence and absence of electricity in equipment. It may come in the form of a pen-shaped testing device, but you can also find advanced tools that detect voltage levels in electrical systems. There are four main types of detectors- High-frequency AC voltage detector, low-frequency AC voltage detector, pulsed DC voltage detector, and continuous DC voltage detector. Each of them has different levels of capabilities. For example, the first one, i.e. high-frequency AC voltage type, is generally mains powered and able to detect charges over 50,000 V. But pulsed DC one is battery powered and lightweight.

Popular equipment like Fluke and Megger voltage tester

Fluke is a popular name for its electrical and calibration tools . The voltage detectors and electrical testers you will get here are designed for use in many applications. From non-contact ones to open jaw and open fork current testers, you can find many varieties here. Find cheap fluke voltage testers if you have budget restrictions. Megger is another name that is popular for its high performing electrical tools. For example, the Megger TPT320 voltage tester helps electricians with voltage indication. It also has some additional features that make it a versatile tool. Dewalt, Milwaukee, and Sperry Instruments are other popular brands to choose from.
