It would be hard to imagine the world today without electricity. It drives almost every industry across the globe. So it’s not surprising that most companies have their electric stations, and they can not work without a voltage tester. But which voltage tester should you choose? Voltage testers are devices used to measure the electrical potential differences in determining if there’s a line current and a phase sequence state. Here are the best voltage testers for electricians.
Before you get to choose, the best voltage testers for electricians will have these features:
-
An indicator light
Some testers are simple — they just tell you if there’s power present or not. Others have lights indicating different levels of power — low power, high power, or something in between.
-
Contact detection
Most voltage testers include contact detection, which means they can detect whether power is transmitted through a wire without touching it. This saves time and reduces the chance of an accident.
-
Visual Display
The classic way to test voltage is with neon lights. A neon light tester produces a spark when it detects voltage, making it very easy to determine if there’s current coming through a wire. The spark can be dangerous if you’re using it on live wires, but it’s very effective for testing whether or not your circuit is dead. LED lights are a much safer alternative that still has the same effectiveness. Some devices will have both options.
-
Safety
Voltage testers should be safe to use in any situation, even in wet conditions such as rain or snow. They should always come with insulated probes to protect against shock hazards and other dangers associated with high-voltage testing operations.
-
Durable design
The best voltage testers are made from durable materials like impact-resistant plastic and heavy-duty metal pieces. They should also be resistant to water or moisture in case you get splashed while testing an outdoor wire. A good warranty can protect against any defects that may arise over time.
-
AC/DC capability
Most home appliances run on alternating current (AC), which runs through wires 60 times per second. Direct current (DC) will only run through wires once per second, and it won’t produce a spark. When you need to check for AC or DC voltage in an object, make sure your voltage tester can handle both current types.
An ideal voltage tester for electricians should have all of these features, and if it does, it will make your job easier. You should also be aware that all voltage testers are not created equal. Some might have more features than others, so we would encourage you to do a little bit of research before you purchase.
