Study guide Flashcards
Why are pipelines normally pressurized?
To prevent condensation and air lock in the system
What are the other components in a slop tank?
2 filter separator in series [not parallel]
Equipment stored in the receiving building is designed for what purpose?
Handle fuel in the JFS under normal delivering conditions
What is the max fuel loading capacity per island during an emergency?
1200 GPM
Peacetime and emergency, maximum fuel receiving rate is 1200 GPM, what is the maximum fuel receiving rate in times of emergency when using mobile emergency power?
1200 GPM
What will happen when the water level in the concrete tank falls below (E2) a certain level? (With Diagram)
a. Water level in concrete tank falls below E2 level, it will initiate the duty pump at break tank to pump, provided the break tanks level is at E1
b. The duty pump in the break tank will stop when the break tank level falls below E2
c. As the water level in the break tank falls, the float valve opens and PUB water will refill the tank once the break tank reaches E1; the next pump on duty will start pumping if the concrete tank level has not reached E1 level
d. The entire cycle will repeat itself until the concrete tank level reaches E1
e. When concrete tank reaches E1, it will initiate the break pump to stop
pumping
PUB pressure head is insufficient in delivering water to the main storage, how can this be resolved?
Install pump, inform PUB, provide intermediate pump house, fire pump
*either 3 or 4 (50%)
Consequence if load demand exceeds electricity generation?
If demand of overloading causing shut down of the generation plant resulting in a major black out.
Design and installation limit for the different types of electrical worker? (How many KBA? For one of the 3 types of electrical workers)
a. Electrician :
i. Capacitor: not exceeding 45kVA
ii. Voltage: not exceeding 650V
b. Electrical technician:
i. Capacitor:
1. Design: Not exceeding 150kVA,
2. Install: Not exceeding 500kVA
ii. Voltage : Not exceeding 650V
c. Electrical engineer : No limit for both
Find the reason why electricity transmission is done at high voltage? (This question the answers given is abit different)
For efficiency (To reduce losses)
a. Reduce energy loss and cost of transmission?
B. Reduce voltage loss
I forgot c and d
Access right in the SCADA system (what are the things that 3 level can do: Operator LEW and engineer can do)
What can LEW do?
a. Provides central monitoring and control of power stations
b. Overview of Base Power Network
c. LEW can control switching which is achieved using Interllution iFix SCADA software and Modicon PLC Remote Terminal Unit
d. Provide for survivability (Harden building, asset dispersion, separation of concentrators) and reliability and availability (Redundancy, Hot standby, ring topology)
Which of the following statement is false about the protective structure (what can it do what is it design for
Structures that have been specifically designed to reduce its vulnerability and to enhance its survivability to weapon effects through passive defence measures
(Don’t even know if this answer is right)
New SQCP will be develop, what are the hardening concept can be adopted for the design of the SQCP
ALL OF THE ABOVE ?
When designing a protective structure, what type of explosion effect needs to be taken into account?
Blast, fragmentation shock, fire ball
Which is not a form of Rigid pavement distress?
Pothole
What are the purpose of shunts?
All of the above
