ASTM D149 Test method for dielectric breakdown voltage and dielectric strength of solid electrical insulating materials at industrial power supply frequencies.
First, the scope and function
Mainly applicable to the breakdown strength and withstand voltage of solid insulation materials (such as plastics, rubber, laminates, films, resins, mica, ceramics, glass, insulating varnish and other insulating materials and insulation) under power frequency voltage or DC voltage. Test.
This instrument is controlled by computer. It is a new second-generation dielectric breakdown detection instrument independently developed by our company. The electronic control system of this instrument is controlled by Siemens PLC. The data acquisition method is optically isolated to effectively solve the anti-interference problem during the test. The software is easy to operate and can display the dynamic curve in real time. At the same time, the boosting rate is steplessly adjustable. The boosting rate can be adjusted according to your needs. The adjustment range is from 10V to 5000V/S, which is the leading position in China. The manufacturer of this function makes the boost rate truly uniform and accurate, and can accurately measure the leakage current data. The test curve can be drawn in real time, the test data is displayed, the judgment is accurate, and the test data can be saved, analyzed, and printed.
The system can automatically determine the breakdown of the sample and collect the breakdown voltage data and the leakage current, and at the same time, the voltage can be quickly reduced to zero at the moment of breakdown. The software system is easy to operate, stable in performance, safe and reliable.
