24.

After morning briefing, i accompanied En. Zul and En. Wan, both of them is street lighting's technician to to their job. They actually in a standby mode which they have to finish the job ( on the spot ) that the consumer asked to or if anything bad happened that involved consumer's right regardless of time.

En. Wan taught me a lots.

There was a few types of light:

1.400w ( highway or federal )
2.150w ( main road )
3.100w/70w ( lanes , 70w is old light system for lanes)

there is a few system for street lighting:
1. Panel controlled -MPJB
- MPJBT
2. Owner - at their house. there will be charge - RM10 ( 150w )
- RM 7 ( 70w )
3. KPLB ( kemajuan pembangunan luar bandar ) - kampung
4.LJK ( Lampu Jalan Kampung )

both KPLB and LJK was paid by government.

there is two type of street lighting pole. one is galvanised and the other one is spun concrete pole. If you see the galvanised pole, that one is not tnb's street lighting pole. That one was maintained by JKR or MPJB.

The distance between street lighting pole and another was 25 meter. The height was 9 meter. is the higher than overhead cable which was 7.5 meter ( SAVR ) .

There is a few brand for street lighting (TNB) :
1. Muarlite
2. Permintex
3.Amat Sinar (known as ASL)


After that, we went to Taman Tun Aminah to see the traffic light that have problems. TNB is not in charge for traffic light but TNB is giving them a supply. Since the traffic light is not working so there must be a problems regarding the supply.

after checking the current and everything was okey at the panel, mybe there was something wrong with the IPC. So they change the IPC and everything turns to be normal again. Sometimes the IPC is broken or loose until not touching the cabel.
