An integrated measurement system for the investigation of high speed and high temperature arc plasma is presented. 2-D optical fiber high-speed imaging system is integrated with four analog channels to gain insight into the complex arc plasma in molded case circuit breakers. The imaging system captures at a rate of 106 images per second. The analog channels permit direct measurement to obtain transient signal, such as arc current, voltage and pressure. To improve the spatial resolution of optical fibers, lens with inhomogeneous dielectric is fixed on the top of each fiber. The Publisher-Subscriber behavioral design pattern is applied to the software and the loosely coupled relationship between glyph and experimental data is once established, the graphic configuration can be implemented for simulation analysis, and the flexibility and applicability of the whole system are obviously improved. It demonstrates that the system provides a better research technique especially for new-generation MCCB with gas-driven arc.
