Technical Challenges :


1. Equipment Failure

GTGC A, Engine Flame Out

GTGC A, GP Over speed

2. Product Obsolete

Gas & Detection System, Power Supply

GTGC PLC product



1. GTGC A, Engine Flame OutDowntime : Often shutdown and re-start @11:30 am since Dec 2009 – Feb

2010Cause : 1 of 10 units Battery 110VDC for Control Console GTGC A drop

voltage

Rectification: Checking all batteries and perform battery replacement.

TCS Panel DC PUMP

EGF



2. GTGC A, GP Over speed

Downtime : 0.83Hrs unavailable unplanned on March 11, 2012 Often shutdown and re-start since Nov 2011 – April 2012

Cause : Spike at GP over speed probe sensor due grounding shield for GP

Probe cable connection failure

Rectification: Ensure grounding shield connection system are correct base on
