This case demonstrates how the Dynatronic VM-S-100 Laser Doppler Vibrometer provides State Grid with a safer, faster, and more accurate way to measure aeolian vibration on overhead power lines. The non-contact system eliminates sensor mass-loading and allows real-time monitoring from a safe distance.

Wujiang Electric Reactor Destruction Test

To ensure reactor safety, vibration acceleration had to stay below 0.075g, exceeding this would halt the test. Due to intense electromagnetic interference and DC bias at the site, the RE-846U system was used. It delivered reliable results under harsh conditions, confirming reactor safety.

The German Lloyd's Register (GL) certification center certified the blades produced by Tianjin Mingyang Company and measured the stress variation and frequency of the blades under various working conditions. The unit completed the test by using SE-860.

Jiangxi Shitan Substation Online Monitoring

The Shitan 220kV substation in Jiangxi monitors vibration on three-phase shells, along with voltage and current, to comprehensively assess transformer operating status in real time.
