Refrigeration Compressor Turbine Not-tripping when needed Trip

[RCA] Refrigeration Compressor Turbine Not-tripping when needed Trip Throttle Valve threatened potential compressor wrecks eliminated.

Root Cause Analysis: K-602 Process Air Compressor too frequent & too lengthy overhauls Eliminated. RCA problem and solution provided.

Steam Turbine Driven centrifugal compressors K-601’s IP case discharge temperatures gradually increases & lead to plant shutdown.

Root Cause Analysis (RCA): Persisting K-601 steam turbine driven centrifugal compressors Discharge Head 3‑monthly leaks.

Root Cause Analysis (RCA): Yearly production reduced due to the steam turbine driven centrifugal compressors leak due to broken instrument.

Root Cause Analysis (RCA): Totally enclosed fan cooled (TEFC) electrical motors rampant winding burnouts. RCA solution provided.

Root Cause Analysis (RCA): Transformers Coolers Weld Joints Oil Oozes Were Eye Sores. RCA solution provided.

Root Cause Analysis (RCA): An 11000/400V electrical transformer and its 11 kV input breaker burst on an occasion incident.

Root Cause Analysis (RCA): Within few weeks failing weigh feeders mechanical variable speed drives (VSD).

Root Cause Analysis (RCA): 50% only heat transferring from Heat Exchanger threatens urea plant commissioning indefinite halt.
