High Voltage or Low Voltage? Which Tester Should You Buy?

Investing in a quality tester, whether new to automated testing or upgrading your test process, is essential. When looking for these testers, you will realise they are available in low- and high-voltage versions. Without the guidance of high voltage tester manufacturers, it can be hard to choose the right one. With enough information, it can be easier to choose the right one. 

This post will discuss the differences between the two and which one you should consider.

High Voltage

This is a form of electricity with high potential energy compared to low voltage. It powers large devices like streetlights and industrial machines.

High voltage is a form of electricity with higher potential energy than low voltage. High-voltage machines can be dangerous if not handled with care. Before using these machines, always consult the high-voltage tester manufacturers.

Low Voltage

This is also a form of electricity with lower energy potential than high voltage. It powers smaller devices like appliances and other electronic devices. The best thing about low voltage is that it can power large devices like high voltage.

Main Differences Between High And Low Voltage.

Let us dig deeper into the differences between low and high voltage to enable you to choose the right one. If you need to power large devices, then go for high voltage. But low voltage will be the best option if you power smaller devices. Here are the significant differences between the two.

Safety Measures

High voltage can be dangerous. You need to have proper safety measures in place when working with it. Low and high voltage is the intensity at which electricity moves through wires. Low voltage is less likely to cause harm, while high voltage can be dangerous. Although low voltage can be safe, it is critical to take safety precautions.


It is more expensive to produce high voltage than low voltage. However, the high and low voltage cost varies depending on the thickness and length. Low-voltage cables are cheaper than high-voltage ones. High-voltage cables are expensive, and they cost more energy. Installation cost also varies depending on the type of cable used.

Danger and Arc Generation

As mentioned above, high voltage is more dangerous than low voltage because it has a high degree of voltage. It is classified as having a high risk of injury or harm. High voltage also generates more electric arc, harming people and the system. The discharges from the voltage release toxic gases that can be a health hazard.

Cables and equipment

High-voltage cables have a larger diameter than low-voltage cables. High-voltage equipment like breakers and motors are bigger than low-voltage equipment. In this case, the high-voltage cable requires careful isolation. The type of electricity you use should depend on your needs. Always go for high voltage if you need more power; otherwise, stick to low voltage.

Safety is a critical aspect when it comes to handling electrical devices. As we have discussed, low voltage is safer than high voltage. Take precautions when using either voltage, depending on your power needs. 

Overall, the suitable voltage type will depend on the power you need. If you are using heavy electrical devices, then go with high voltage. However, if you need less power, then it is advisable to use low voltage.
