09:32 Aug-24-2005 UT at insolation integrity detecting criterea
Can some one help me by sending what will be the range scaning when at isolators integrity checking by using the ultrasound dectector like follows: at high voltage between 13,8kV & 138kV our great difficult is to stabilish the inspecting criterea, by the way at now we`re using: at 7 dBmV to 0 dBmV ----- good isolator at 1 dBmV to 10 dBmV ----- needing ground isolation measure soon as possible more than 10 dBmV ---- imediatly repair or replacement Can you send me more informations about measurement criterea to Corona effect limits? Thank you.
The compact inspection head is suitable for thermographic ndt
tasks. The uncooled infrared camera
is specially developed for
NDI-tasks and offers a thermal sensitivity until now known only
from thermal imagers with cooled detector. All required
components and functions are integrated into the inspection-head.
You will only need an ethernet cable to connect the sensor with
the evaluation system.
