Corona Pointer


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.

Applications :

• HV Labs
• Switchgear
• Substation
• Transmission Lines

Functions :
1. Color LCD screen display, friendly interface, intuitive display and easy operation. It can determine the
location of the failure point of the partial discharge point, and has fault recording, storage and playback
2. Built-in inspection task management system. Data is compressed, interconnected, and communicated in
compressed form.
3. Intelligent RFID electronic tag inspection function, which supports the interconnection of cloud platforms,
and can realize intelligent inspection and joint fault diagnosis on site.
4. Equipped with a camera with a long-distance function, it can also record photos of the discharge part
while determining the location of the partial discharge fault.
5. Support GPS inspection and positioning anagement, the system supports two-dimensional
code scanning and one-dimensional code data reading.
6. Equipped with a headphone output function, which can convert the ultrasonic signal into an audible
sound signal for the adult ear, which is sent by the headphone, which facilitates inspection operations and
improves efficiency.
7, Strong anti-interference ability, can be applied to noisy environment, not affected by external
environmental sounds, has a strong directionality, can quickly and accurately locate defective equipment.
8. Equipped with a high-brightness red laser aiming device, users can easily locate targets even under
strong light.
9, High sensitivity, long distance inspection, can achieve long-distance online monitoring, no power outages,
no close proximity, can be operated in a safe location.
10, Built-in diagnostic software, real-time display of test results, and supporting special management
software, can achieve test report generation, printing, search and other functions, easy to search.
11. It adopts large-capacity and high-performance lithium battery for power supply, low power
consumption design, long battery life, easy to carry, and suitable for a variety of work occasions.
12. It can be tested on vehicles with a driving speed below 30km / h, which can realize fast detection.
