1. Scope and function
It is mainly suitable for the test of the breakdown strength and withstand voltage of solid insulating materials (such as plastic, rubber, film, resin, mica, ceramic, glass, insulating paint and other media) under power frequency voltage or DC voltage.
This instrument is controlled by a computer and is completed by the new intelligent digital integrated circuit system and software control system independently developed by our company, so that the boost rate is truly uniform and accurate, and can accurately measure the leakage current data. The test curve can be drawn in real time, the test data can be displayed, the judgment is accurate, and the test data can be saved, analyzed and printed.
