Dielectric damage measurement is a fundamental method in insulation testing, which can effectively detect both overall damp deterioration of electrical equipment insulation and localized defects. It is widely used in electrical manufacturing, electrical equipment installation, handover, and preventive testing. The dielectric damage measurement of transformers, reactors, capacitors, casings, and lightning arresters is the most basic method for assessing their insulation performance. This method breaks through the traditional bridge measurement technique by using frequency conversion power supply technology, a microcontroller, and modern electronic technologies for automatic frequency conversion, analog/digital conversion, and data processing. It offers fast testing speed, high accuracy, automatic digital operation, and ease of use. The power supply utilizes a high-power switch, outputting 45Hz, 50Hz, and 55Hz pure sine waves with automatic voltage regulation, providing up to 500V. An automatic filter eliminates 50Hz interference, making it suitable for substation electromagnetic interference field tests. It is widely used in the power industry for testing transformers, reactors, casings, capacitors, lightning arresters, and other equipment. Performance Characteristics 1.The instrument adopts Fourier transform digital filtering technology to measure capacitance, dielectric loss, and other parameters. The test results are highly accurate and allow for automated measurements.
