When we talk about thermal imaging, we mean serious business. Thermal imaging is used to detect the temperature and conditions of your electrical equipment. Doing the tests annually is recommended, as businesses can suffer fire damage or injury in the event of an electrical incident. Doing these tests on an annual basis not only reduces the risk of electric fires but also improves the system performance of your electrical equipment. At any rate, excessively high temperatures in your electrical equipment isn’t a good thing so it’s important to test them regularly.
