False Hydraulic Fault Resolved After Module Connection Fix
"A rising hydraulic oil temperature trend triggered a flag on Kavaken. After cross-checking similar turbines, the team discovered that the issue wasn’t mechanical but caused by loose module connections creating a false fault signal."
The Impact
The Issue
Irregular behavior was detected in the hydraulic oil temperature readings. Possible root causes included oil contamination, accumulator pressure drop, valve leakage, or a faulty pressure sensor in the hydraulic system.
The Action
Kavaken noticed that one turbine’s hydraulic oil temperature was trending higher than comparable units across multiple sites and advised checking for sensor or module issues. Following this guidance, the service team inspected the hydraulic unit and found that vibration had loosened the module cables, causing false readings. The cables were reconnected and secured, which immediately resolved the issue. The client confirmed that the fault was not mechanical but sensor-related.
