■ Product Overview

Partial discharge tester uses Windows system operating platform, can freely choose ellipse, straight line, sine wave display, two-dimensional, three-dimensional graphic analysis and spectrum window, Q-V-F three-dimensional characteristic window, static to a cycle of test voltage local discharge pulse detailed measurement, observation, analysis. Digital window opening operation can be carried out, window opening at any phase, single window, double window optional, elliptical 360° rotation, in order to avoid the influence of interference on measurement. Multi-channel measurement and digital differential technology can flexibly form the pulse polarity identification or balance measurement loop, effectively suppress the interference pulse signal. Spectrum analysis can effectively reduce background interference. Multi-channel input channel, which can increase the voltage at one time to measure six local emission signals of the sample (expandable), which can easily analyze the source of local emission signals. On the whole Chinese character operating platform, it is convenient for frequency band selection, gain conversion, spectrum analysis and 2d and 3D graphics display. In addition, the system can also print or save a single graph, save continuous time graph data for analysis.
