Electrical testing equipment refers to a variety of tools and devices used to measure, analyze, and ensure the safety and performance of electrical systems. These instruments can test voltage, current, resistance, and insulation, helping technicians identify issues in electrical circuits and components. Common types include multimeters, oscilloscopes, and insulation testers. Using electrical testing equipment is essential for maintaining the reliability of electrical installations in homes, industries, and commercial buildings. Regular testing can prevent electrical failures, reduce the risk of accidents, and ensure compliance with safety standards. Proper use of these tools helps technicians diagnose problems quickly and accurately.
