2. Valve leakage detection by means of UNISCOPE devise was presented.
3. Investigation of air inflow detection possibility on vacuum equipment was carried
out. Air inflow detection possibility was confirmed.
4. Investigation of RC cooling tower support columns monitoring possibility was
carried out. Monitoring possibility was confirmed.
5. AE testing of 2 power transformers was carried out. Insulation defect was found
based on the results of testing.
