Thiết bị kiểm tra phóng điện cục bộ NBD Technologies ADD
The ADD is designed to detect partial discharge in medium voltage components by direct contact on energised conductors. We developed a contact method using ultra wide band radio frequency detection technology. Using the ADD on a regular basis will help you to prevent failures, customers complain and costly investigation to identify the source of a problem or potential problems. The probe is placed in direct contact with the energised component under test. The partial discharge level is displayed on the ADD and on the remote display. The remote display gives a wireless reading of the probe’s measurement. The measurement range is 0 to 60dB and the display will show ‘‘OL’’ if the reading is over its maximum. The ADD efficiently filters the influence of corona type activity thus making it an ideal tool to detect insulating material internal partial discharge.
