KPM Corona Pointer is an ideal equipment for condition-based maintenance programs. Online partial discharge testing is a method of inspecting the insulation of electric power systems while equipment remains energized and in service. Corona Pointer is based on online Ultrasonic PD sensor technology. The product adopts a low power consumption, low noise, and high sensitivity design. By optimizing the signal acquisition and processing algorithms, fast capture of discharge pulses can be achieved. It performs a real-time ultrasonic measurement and superimpose it on the visible image with laser pointer . This gives user a pin pointing idea about the PD source.
