The project site sits in a middle of a jungle in Semenyih. Its main function is to process the solid waste produced daily to useful energy to assist TNB to generate power for industrial and household use.
The termination and commissioning time for the overall power system came in so sudden. I still remember that my boss just received this deadline a week ago from his main contractor. Since it is our customer’s request, we have to fulfil what our customer wants.
Site visit helps to educate me from what I have read in the project documents passed down to me. I have a chance to experience the Field Acceptance Test for the functional motors.
To supply power to them, we need to first bring up the Circuit Breakers for the power surge / short circuit protection. Now we come to the most important part of the procedure - to switch on the Circuit Breaker (Fig.1).
Fig. 1 Switch Board.
Some of us might think that turning on the breaker is like switching on a light. Right? Wrong...!!!
It nearly freaked me and my other colleagues out when my boss attempted to power on the breaker. Once the switch is moved to the ON position, the magnetic circuit immediately attracts a steel bar to connect the high voltage circuit. And due to the dust collected on the Bus Bar (Fig.1), all of us witnessed a huge electrical sparks.
Full of sweat, I was told later that this is normal. Imagine touching a 22kV(live) Bus Bar, I will turn into dust in a matter of minutes. I really feel a bit nervous with my job now. Adding to a few stories of my colleagues getting electrocuted for several times, I am still yet to recover from a slight trauma.
Apart from the danger of high voltage devices, the construction site condition is also a threat to the workers there.
Just check out the few pictures that I have taken below. The platform (white) is only 1.5 feet wide. One mistake and I will land straight to the ground from 2nd floor.

Man really pray hard that I survive through out the commissioning period.
Till then, sign off from Puchong.
