EMEK received a letter from HYDROCHINA regarding an oil leakage issue with protection CT serial number 16C 0028. EMEK and its agent RABAF Engineering investigated the leakage and found it was caused by a loose gasket. They instructed tightening the bolts around the gasket with 24nm torque and monitored the leakage. After 24 hours, the leakage had successfully stopped without damage to the CT. EMEK guarantees the oil level is sufficient and the CT can be energized without issue.
