Week 1, 7th April

In the morning, i followed Mr. Tan to the gas turbine hall for gas turbine motor preventative maintainance (PM). In the control room, Mr. Tan explained to me that the code 88 is for motor system while code 23 is for heater system. The insulation resistance must be larger than 2M ohm and winding ohmic value must be balanced so that the system is safe.

In the evening, I followed abang Razak to circulating water pump hall to further observed their work.
