Product Description
■ Product Overview
Dielectric loss measurement is a fundamental method in insulation testing, capable of effectively detecting overall moisture ingress and degradation of electrical equipment insulation. , as well as localized defects. It is widely used in electrical manufacturing, electrical equipment installation and handover, and preventive testing. Measuring the dielectric loss of transformers, instrument transformers, reactors, capacitors, bushings, surge arresters, and other components is the most fundamental method for assessing their insulation performance. By employing variable-frequency power‑supply technology and leveraging microcontrollers and modern electronic techniques, automatic frequency conversion and analog… / Number conversion and data operations , It achieves strong anti-interference capability, fast testing speed, high accuracy, fully automated digitalization, and simple operation. ; The power supply uses a high-power switching power supply. , Output 45Hz and 55Hz Pure sine wave , Automatic pressurization , Can provide up to 10kV the voltage ; Automatic filtering 50Hz Interference—suitable for on-site testing in environments with significant electromagnetic interference, such as substations.
