I followed En Elias and his team to Kampung Parit Haji Yakob. We need to bring down conductor ABC 3x16+25 to let customer cut down trees. There were 12 trees they need to cut down. We wait there for almost 4 hours and put the conductor up at poles. On the way back to the office, En Elias removed creepers at stays to avoid any breakdown in the future.

Figure shows a staff untied the conductor from its holder.

Figure shows the conductor was on the ground and customer can cut down the trees.

I stayed in the office and learnt more about load,capacitor bank and earth pipe.

• load is a measure taken from an equipment that has voltage coil or a motor (such as a compressor)
• capacitor bank is used to collect current (extra/wasted) to avoid current loss.
• earth pipe is a kind of metal (copper) which is about 7 ft. length, located underground. Earth pipe is used to avoid accident and save properties if electric trip happens.

12 May 2010
I followed En Wahi and En Yakob teams again. We set up LPC meter like yesterday but there are 4 meters today. It is a new factory with 4 blocks in Jalan Perusahaan 1 in Parit Hulu Industrial Area.

1. The connection for LPC meter : Tx->bus bar->current Tx->test terminal block->LPC mater
2. For the current Tx or CT, we must put its side labelled 'S1' as the bus bar is going in it and going out from its side labelled 'S2'. CT is made of copper coil; function to change voltage in the bus bar.
3. The test terrminal block has 2 parts: current and voltage parts. The voltage part is covered because it is a high voltage side.

11 May 2010
I followed En. Wahi and En. Yakob teams to Bakri Industrial Area. A factory had problems about the electricity supply. They claimed that TNB doesn'nt supply enough electricity. The Foremen, En. Samzaini took the reading at the meter by using a multimeter. The result are (take phase-to-neutral wire):

1. R=213 V
2. Y=215V
3. B=223V

With the result, it shows that TNB supplies enough electricity to the factory. For single phase, TNB supplies 230 V +- 6%.

Then, we went to new build Police Apartment to set up LPC meters. The setting up of LPC here were challenging because the work space is small.

7 May 2010

12 April 2010

I went to TNB Cawangan Tangkak for Technical Sport. Actually, the Area Manager advice us to come for this event. It was a good opportunity for me because I can see and learn about so many things. There were many categories had been presented such as poles dressing, fault finding and lamp-post installation. In these competition, not only the TNB staff took part but there were also contractors. All the participant showed their teamwork and quality, but the most important thing is they always put the safety first.

9 April 2010

We went to Kawasan Perindustrian Bakri. The underground cable from a substation need to be replaced with a new one to avoid breakdown in the future.

3. Then, we went to substation or P/E Jalan Ibrahim. The old IDB (indoor distribution board) need to be replaced for the new feeder pillar for customer future convenience. My supervisor used a walking meter to take the distance where new cable are needed for the new f/pillar.

Indoor Distribution Board

note: P/E pencawang elektrik

7 April 2010

1. I learnt the flow of a supply project. The flow starts from the receiving of form from the applicant until the budget for the project is approved.

• if the budget is up to 20K only, the approval can be given by the Branch Manager.
• if the budget is up to 50K, the approval must be given by the Area Manager.
• higher budget must be approved by more important person in TNB thus, it will take longer time than a project with lower budget.

2. I followed En. Zulkarnain to site of 10 units shop in Payamas, Tangkak. These shop will be supplied from a feeder pillar which is only 100 meter away.

3. We also went to Sek. Keb Sri Jong to make estimation for its new block.
