Which condition could require immediate system attention and lead to a shutdown?

Increased vibration is a critical condition that signals potential problems within machinery and equipment in power engineering systems. Vibration levels that exceed normal ranges can indicate that components such as bearings, rotors, or couplings are experiencing excessive wear, misalignment, imbalance, or impending failure. Monitoring vibration is essential since unchecked increased vibration can lead to catastrophic failures, resulting in not only costly repairs but also safety hazards for personnel and equipment.

When increased vibration is detected, it often necessitates immediate investigation and possible intervention to assess and rectify the underlying issues. Addressing these concerns proactively can prevent further damage and ensure the safe and efficient operation of the power system. Other conditions mentioned, such as normal vibration levels, stable temperature, and consistent flow, indicate that the system is functioning as intended and do not typically require immediate attention or present an immediate risk to safety or operational continuity.
