Reasons To Use Voltage Testers

Voltage testers are testing devices used for checking the flow of electrical current through electrical circuit. To use voltage testers, electrical current must be running. However, voltage testers are usually used to confirm that the electricity is shut off before starting any kind of electrical work. There are many different voltage tester models depending on the application and type of job that needs to be completed.

The benefits of voltage testers are commonly neglected, although there are many. These simple testing devices are reliable and effective for ensuring safe and proper operation of every piece of e systems, insulation checks with voltage testers are highly recommended and in some cases, they are even a legal requirement. If you are able to predict, or timely test the end of the reliable service, you can avoid costly downtime and unplanned maintenance. Testing is the key, but it can be done only with a reliable device, such as the voltage tester. Here are few reasons to use one.


Dependable Results – Voltage testers provide dependable results. When a voltage tester is positioned high enough, it can effectively measure insulation resistance, but try not to position it too high not to over-stress the insulation during testing. To ensure dependable results, you must use the right type of voltage tester for your application. Once the voltage tester is connected to an electrical circuit, it provides immediate reading.

AC And DC Currents–Voltage testers are able to check both AC and DC currents. Smaller businesses and for home applications, AC current is used, while car stereos, for example, use DC current. Before use, set the meter on the appropriate range to get accurate results.

Portability – There are portable voltage tester models which use high-impedance voltage sources for safety reasons. So, the output voltage of these testers falls to a fraction of the nominal value, while the currents are flowing. However, the charging current decreases over time and the output voltage of the voltage test rises. But not all testers are the same. Therefore, in many cases, the desired test voltage is not achieved.

Maximum Value – When choosing a voltage tester, it is very important to consider and examine the load curve. If diagnostic testing is intended, consider the maximum value of insulation resistance that the device can measure. Try to find out correct numbers to get the maximum benefits out of your voltage tester.
