Visiting Trip to TNB-R (27/3/2008)

Well, the UFO picture before was able to attract some curious people to wait for my post on my visit to TNBR on 27 of March. I must apologise to them because of my late publish on this post, because the trip was nothing but boring and basically the trip was used to covered us up for extra 10 marks so as not so many of us will fail this subject. BUT eventually I do screwed up for this final and last paper of the semester.


F*CK!!!


Relax, now let's browse the gallery:

The main entrance for TNB-Research located inside UNITEN.



Auditorium

The organiser: Mr Aziman



THIS IS HIGH VOLTAGE LABORATORY:

Below: 400kV rms. PSZ400-1000-25: Used to test an object under high voltage for a period of time.

Full view:
The UFO shape-like disc is called Corona Disc, the design is completely out of sharp point to prevent high voltage stress and produced little lightning in the lab.
The sample is immerse into this oil liquid as the medium of conduction.
Below: AC Power Frequency & Partial Discharge Detector RSK100-1000-10. This device is design to test high voltage stress of a sample (usually cable) but at a low power rating.
Left hand side is the capacitor divider with the sample and connected to the measurement instrument.
Right hand side is the transformer to step up 415V to 40kV.
The input voltage regulator for RSK100-1000-10
A zoom on the 1:10 step up transformer.
This is the final device and where the UFO came from...

Lightning impulse voltage generator: SGSA 1200kV-60kJ. The main function is to generate 1.2/50uS of voltage.

This toy had 12 stages and able to generate 100kV for each stage. The purpose is to simulate the lightning effect on the sample.

The spark gaps: Mechanical switches to make up the mechanism of voltage boosting.
Below: R-C filter in series to divide the voltage for measurement
Continue: Connecting box from RC filter to control room
Below picture show the failure sample of XPLE power cable.

Up and Down: New XPLE Insulated Power Cable

Up: The center 3 aluminum core is the conductor for 3 phase system and each are isolated by an insulator and the ground copper cable is at the outer later. Then the cores are surrounded by water insulating medium and lastly the water jacket

Down: The cable you frequently saw at night when someone drilling the "Longkang" cover in front of your house. These are XPLE power cable.
Transformer:
Below: XPLE Insulated Power Cables test on water resistance and effect of water leakage on water jacket.
Up: Laboratory to detect the water tree(Water leakage from outside) inside the water jacket

Down: A sample with water tree

Up: Lightning Information Center

Down: Customise real time lightning display (LTraX™) which will indicate the exact spot of lightning occurred in peninsular Malaysia.
Zoom on the monitor to show the lightning activities on past 2 days.

TLA: transmission Line Arrestor (Read yourself, my lecturer's best way to avoid his paid duty.)


My lecturer asked me: Do you learn a lot in this trip? Are these thing impressive?
I answered: Impressive, very amazing piece of engineering.....

But inside my heart, these are only the real apparatus to carry out high voltage test, but no one will know except the staffs over there know whether this this can work or not. Unless the make the test in front of us

So in conclusion:
I come, I see, I forget...
