WeeK 2 (12th~16th April 2010)

Day 7 (12th April 2010)

• Download Infrared pictures, Photos and Ultrasonic graph from flirimage server for report formatting.
• I need to do report formatting for Mr.Rehanfairuz (Team Leader) team.

Client: TNB Distribution KL Pusat

Date of Inspection: 9th April 2010

No. of Reports: 11 (for each Pencawang Elektrik)

• From last week assignment, my supervisor (Mr.Khairil Fitri) recommend me to read Bangkok Conference Slides. It is easy for me to be at the site after i understand what actually the company do.
• After finished my work, i have some extra time to read the slide.

BANGKOK CONFERENCE SLIDE

There are 8 topics discussed in this slide which are:

1. Utility's target - Zero Downtime
2. Preventive Maintenance as the least -cost approach towards Zero Downtime.
3. Condition Monitoring as an important input in Preventive Maintenance Program.
4. The Role of Infrared Scanning in Condition Monitoring and the Speacial Capability of Thermoflir Infrared Camera.
5. Case Study Demonstration effectiveness of its high technology in Condition Monitoring.
6. Technology, Procedure and Responsibility.
7. Actual Data.
8. Complimentary System (Digital Ultrasonic Scanner).

• For the extra time, I finished read the first 3 topics.

1.Utility's Target

As we all know, electricity is a basic necessity in our daily life. So, we know the main supplier of electricity in our country is Tenaga Nasional Berhad, TNB have to make sure consumer get this basic necessity in every hours.

• Target - Zero Downtime: Continuous supply of electricity is paramount to highly critical installation. Thus, 'Zero Downtime' is primary target.

2.Preventive Maintenance

"Prevent is the better way before the Flash Over Occur"

• Is the least-cost approach towards zero downtime.

3.Condition Maintenance

There are 3 types of condition maintenance which are:

i. Breakdown Maintenance, BM; is maintenance that is undertaken after a component fails.

ii. Scheduled Maintenance, SM; is where a ficility is taken offlne at fixed interval and scheduled maintenance is performed.

iii. Preventive Maintenance, PM; allows the early detection of potential equipment failure. This is also one of the maintenance that prefered by TNB due to least-cost approach.

Condition Monitoring System

• Before the problem or accident happen (i.e Flash Over), the best way (least-cost approach) is to monitor the condition of the substation.
• The condition of substation can be monitor using Infrared technology.
• Infrared technology:

- Service provider could asses teh condition of the electrical power equipment under 'live condition'.

-This is very important as the infrared scanning operation wil not disrupt the present supply of electricity to the respective clients.

Day 8 (13th April 2010)

• Download Infrared pictures, Photos and Ultrasonic graph from flirimage server for reports formatting.
• I need to do report formatting for:

• Studied Bangkok Conference Slide

4.The Role of Infrared Scanning in Monitoring Condition and Speacial capability of thermoflir Infrared Camera.

The Basic Principle

1. Each object has its own 'heat capability'.
2. When the object is worm/hot, it produces radiation.
3. The radiation can be quantified in term of frequency.
4. The object is hotter ~ the higher the radiation~the higher the frequency intensity.
5. This frequency - detected by infrared sensor and sends the data over the infrared system processor.
6. The infrared system processor will subsequently process the data and projecting an infrared image on the screen.
