In order to real-time monitor the high-voltage corona discharge,an ingenious,portable and inexpensive corona testing equipment is needed and can be widely used in the future.Through requirements analysis,an UV flame detector to count the number of photon and evaluate the corona intensity is used.In order to improve the detection sensitivity,an ultraviolet system was designed which composed of double-convex spherical lens,super-hemispherical solid immersion lens and an UV detector.The system is simple and compact,together with greater energy concentration ratio to improve detection capability.Designed by Matlab calculation and lighttools simulation,the test result of the sample machine shows that the system can fully meet demands.
