Buyer Guide
How to identify best voltage testers
It is okay to be in a dilemma on the item you should purchase. It is okay to spend hours looking for the right item.
But what if the dilemma takes longer than expected? What if you can’t differentiate the right item for you?
If you are on crossroads on the best non contact voltage device home use to purchase, we got you. The below questions and answers will not only simplify the search process but as well as the help I saving time.
And the good part?
You will get to know how the non contact voltage testers work.
No further ado, let’s get the ball rolling.
Which non-contact voltage test device is right for me?
Non contact voltage testers have a testing range. But first, what does the testing range imply? It refers to the voltage range the non contact voltage testers can detect. Basically, there is a standard voltage and low voltage, and high voltage.
Standardly, the voltage test device has no problem detecting the high and standard voltage. Hence, the question remains if you need even the negligible levels of voltage to be detected.
How can you bet that?
If possible, get a voltage test device whose test range starts from a low level. Also, it will get better if you can get a dual voltage tester. Why?
That is for the mere fact that you can test multiple types of equipment without any limitation.
And another thing-
Durability is un-compromisable. In other words, the plastic casing should be significantly reinforced as well as the bright red clip.
Also, in an environment that you are likely to multitasking, an automated voltage test device is recommendable. That is, it should have an auto power off system, which reduces the workload as well as save on power.
And finally?
If you are color blind, then the flashlight colors might be a little confusing. Thus, ideally, have a voltage test device with a beeping alarm. Further, if you will be carrying the tester along, consider a clip alongside a lightweight.
Why is non-contact voltage test device necessary?
The perfect way to answer that question is to look at the uses of the voltage test device. But do you know the type of tool we are talking about? Let’s get that out of the way first.
A voltage detector is a power tool that tests an electrical field’s presence in an electrical circuit.
Consequently, it is used when repairing electric circuits, detecting the live and neutral wires, and any other situation you need to verify the electric current’s presence.
But why necessarily a non-contact voltage test device?
Unlike the non- contact voltage testers, the contact testing function by getting into contact with the wires. Needless to say, that puts you at risk of electric shock. And I know you are aware that some of the electric shocks lead even to death.
So what’s the point?
This is the pure truth; using a non-contact testing meter guarantees a high safety level due to its non-contact way of functioning.
To top it off?
These machines are pen-shaped hence, a mini-size and lightweight. Actually, some of them will have a pocket clip as it is the case of the uncomparable HVAC non-contact voltage detector.
How does non-contact voltage test device work?
Now let’s get to know how the non-contact voltage testers work.
As I said earlier, they mainly function in a non-touch way. They are pen-shaped with voltage sensor on the tip. The user holds it on the upper part with the tip facing the ground or the circuit.
How does it detect the voltage?
The voltage testing meter detects the presence of voltage through capacitive coupling. Are you scared of the physics terms? Relax! I will break everything to the finest details.
In simpler terms, there are two capacitors at work. First is the live wire and the other one is the voltage sensors on the pen.
When there is a complete circuit with current flowing, the sensors detect by use of the atmosphere air as the virtual wire.
And the bonny part?
On the part the user is holding acts as a conductive plate. Technically, touching the metal plate provides the “earthing,” thus completing a capacitively coupled circuit.
Now, the sensor detects the presence of the current in the non contact tester pen. And boom! It is a bright shining flashlight or a beeping light.
How do voltage sensor work?
Broadly speaking, there are two types of sensors,
- Inductively coupled voltage sensor
- Capacitive coupled sensor
To begin with is the inductively coupled tester. In simpler terms, inductive coupling implies that the current flow creates a magnetic field, which in return creates another field.
How is that possible?
The sensors, in this case, have a winding like the style on the pen tip. When there is a voltage in the testing circuit, it results in voltage in the windings. Thus, an electromagnetic field is created in the sensor windings.
Now here is the kicker,
The testing meter works by detecting the electromagnetic field, which by now is detected on the windings. Thus flashlight will go on or the alarm.
However, that will not be the case if there is no current in the wires. You can guess why? Damn, right, because there wouldn’t be any electromagnetic field.
Almost done! The last type of sensors – capacitively coupled sensor
these sensors have parasitic relations. That is the sensor tip and the live wire conductor and the sensor capacitance to the ground capacitor.
Which is this ground capacitor?
You have probably heard you need to touch the metal plate for the testing device to function from your user manual or instructor. Did you ask why? The body contact provides the ground reference to earth the tester.
The key part?
When the tip is placed on the live wire, the coupled sensors detect the current and allow it to flow through the non contact tester pen, completing the circuit. Resultantly, it is the light or the alarm, which is the volt alert.
Can non-contact voltage detectors test for polarity?
We all go for multi-purpose items. Unfortunately, that is not the case with the non contact voltage testers. This is the thing, as the name suggests, it will only indicate the voltage, not the polarity.
Is there any good news?
Yes, I got some heart pleasing news. There are non-contact voltage detectors that are designed to test for polarity. These test pens buzz or light up when they detect the electric field.
However, there is one small catch. If you need a voltage and polarity tester, a millimeter will sort you. But not without the contact working, which risks an electric shock.
