An IR tester is a valuable tool, designed to support insulation resistance tests that affect a range of project quality and safety considerations.
By learning about IR testers and how they work, you can plan to achieve better-quality results across a variety of professional tasks. An IR tester can help you ensure safety while working with insulation and electrical gear.
Wondering what an IR tester is and how to use one? Here is everything you need to know.
What is an IR tester?
An IR tester, or insulation resistance tester, is designed to evaluate the condition of electrical insulation relating to cables, transformers, switchgear, and other equipment.
Applying a direct current voltage to a conductor, an IR tester measures current that flows through insulation and determines how much current is leaking. An IR tester can establish electrical current patterns and identify problems that may compromise the efficacy of electrical insulation.
IR testers come in a range of sizes, and output voltages can vary depending on your device’s design and applications. In most cases, handheld 1000V devices are sufficient for testing 600V equipment, while you may need a 15,000V or higher-voltage IR tester to work with high-voltage equipment.
Why IR testing is important
IR testing is essential, allowing for important safety checks that can catch hazards and reduce the risk of injury or harm.
Using an IR tester, you can determine whether electrical insulation is working correctly and pick up on current leaks that may be affecting non-current-carrying metal parts. By knowing how current flows through insulation, you can resolve problems and repair damage that could pose a safety risk in the long-term.
Maintaining IR testers
Maintaining your IR tester is an important consideration. Looking after your testing equipment can help devices to stand the test of time, as well as ensuring that accuracy and efficiency are preserved.
For most IR testers, basic care includes periodic cleaning with a soft, lightly damp cloth, followed by a clean, dry cloth. While it’s important to remove dirt from your IR tester, alcohol and solvents should never be used for cleaning.
If your IR tester uses rechargeable batteries, follow the manufacturer’s battery maintenance recommendations to ensure the best possible results. Regularly check your device for signs of damage or broken parts that could affect functionality.
How to choose an IR tester
When selecting an IR tester, it’s important to think about your project needs, helping you choose a device that is well suited to your requirements.
A good IR tester can last for several years, so it’s often worth making an initial investment to purchase a high-quality model.
Before you choose your testing device, shop around, and compare your options. Choose a device that is designed for the kinds of tasks you work on most often, and select a tester that features a clear display and produces highly accurate measurements.
