week2 day 5: trainee engineer~

salam~

funny isnt it when people address u as a trainee engineer when u urself know..u cant even design a 30 socket single line diagram..haish..but like my mom said..just except it as a doa..amin~ ^_^

so today..since its friday..nothing much can be done in the morning..everyone was busy..bosses was going here and there..they are all going for meeting here and there..plus the collapsed fence near the runway..everyone was out..leaving me and the rest of the clerks at the office..so i fill my free time searching bout the transformer..reading on IP code..and before en din go to subang for his meeting..he told me to check the transformer plate later in the evening when the representative from ABB transformer come for testing..my hope was lifted..yes! site visit! so i waited for anyone who i can ask to send me there..so i sit there patiently..reading this and that..completing my log book..and waited~

friday prayer~

then on the evening..i heard someone called mr azhar..this is the funny part..he told the person on the phone to come to the office to see the trainee engineer..omg! thats me! haha..so i waited who is coming to see me? haha..then it turn out to be the chargeman and hj radzi the contractor..they came to check on the previous test on transformer..after seaching the whole office..then searched the drawing library..they found it..luckily the chargeman, mr dahari said i can follow them..so i did..yey! and here some picture form the visit to the main intake substation...here the incoming supply of 33kV from TNB were stepped down straight to 415V for few areas..but for other area and building..33kV are distributed to each..i asked the chargeman..why didnt they stepped the 33kV to 11kV first? he said, the designer think maybe in the future the complex would need more than 415V so they directly distribute the 33kV not 11kV..see..how advance the engineers back then? amazing~

oh..here..enjoy the pictures~

: total km travelled each day..95.7km bangi-lcct-bangi :


: plate of the broken transformer:
its 1000kVA..one of the smallest tx..there are bigger tx..havent get the chance to see..yet~ ^_^


: high voltage side 33kV :


: low voltage side 415V :
the red phase's coil burn due to environment factor and maybe manufacturer's defects
still waiting for full report from ABB transformer


: main intake (33kV) from TNB; all are underground :


: 3 phases..red yellow blue :


: see the left orange cable? that was tapped to the bus bar form generator set substituting the broken transformer :


: 2 generators are used; 1 for back-up..they are alternating each genset in 12 hours..here are mr dahari, mr megat and mr maswan..switching the right genset on for another 12 hours resting the left one:

the procedure is quite easy..
1: check diesel and engine oil levels
2. on the 2nd genset; setting it to parallel 
3. set the 1st genset to parellel from current single..
4. after few second..let both genset synchronised
5. set the 2nd genset to single
6. set the 1st genset to single
7. off 1st genset
8. 2nd genset take over the system for another 12 hours 
9. after 12 hours these procedures will again repeated by switching on the 1st genset letting the 2nd genset rest.

its interesting indeed! ^_^
wish i could do it next time~


: mr dahari showed me the underground room which place these cables..thanks so much! :

: the testing device, DC test :


: diagnostic test device :

so that'll wrap-up week 2 activities..

schuzyy cant wait for monday to come! ^_^
