INTRODUCTION
Electric Panel Factory at Dammam has decided to modify compact substation production line by replacing Oil Ring Main Unit (RMU) with sulphur hexafluoride insulation (SF 6).
Replaced Oil Ring Main Unit (RMU) by SF6 insulation
OBJECTIVES
1.1. Replace Old and Obsolete Oil RMUReplace Old and Obsolete Oil RMU
2.2. Use SF6 RMUUse SF6 RMU
3.3. Select the best RMU Select the best RMU
4.4. RMU should be delivered in six lots / 2 RMU should be delivered in six lots / 2 year year
5.5. The cost of oil type RMU is 15,000 SRThe cost of oil type RMU is 15,000 SR
SF6 in RMU
SF6 gas is used in electrical power equipment
It is insulation and arc quenching medium in RMU

Value Study Summary Comprising between SF6 and Oil RMU
Reduce the cost of compact substation Easy to install Increase customer acceptance of co S/S Increase the Factory market share RMU`s manufacturer will provided technical
support for changing implement the new design
Reduce maintenance cost Increase breakdown The difference in price between oil and SF6 is
slightly very small
Implement Plan 1- How Should it be implemented?
The propped RMU from Saudi Lucy will be discussed with factory , purchasing and engineering managers to overcome any road blocks prior to management presentation
2- What should be changed and in what sequence?Within approval the purchasing department should finalize the price and delivery time. Then , the designer shall revise the drawings to meet new approved SF6 RMU.
3- Who should do it?Engineering department and do necessary changes prior compact substation submittal to procurement department
Implement Plan 4- How long should it take? Two weeks
5- Any deadline requiredAs per management report forcast
6- Implementation cost , internal house30 hours for engineering 20 procurement 50. Total cost SR 3000
