Electrical testing is the process of evaluating the performance and safety of electrical systems and components. This includes checking the functionality of devices, measuring voltage and current, and ensuring that equipment meets industry standards. Testing helps identify potential issues that could lead to failures or hazards. Various methods are used in electrical testing, such as insulation resistance testing and continuity testing. These tests are essential for maintaining the reliability of electrical installations in homes, businesses, and industrial settings. Regular testing can prevent accidents and ensure compliance with safety regulations.
