Pre-Training Self Assessment – Question Data Bank

BEST PRACTICES IN DISTRIBUTION
SYSTEMS OPERATION AND MAINTENANCE (O&M)


Pre-training Self Assessment – Question Data Bank

The participants may wish to assess their knowledge about Operation and maintenance issues – tools, techniques, etc, its importance in reducing distribution losses, better quality regular power supply, and customer satisfaction before the commencement of the training. A comparison with the self-assessment after the training would help them in assessing the benefits of the training.

1. Which of the following contribute to the deterioration in the power sector distribution system performance?
a. More than optimum loading of DTRs
b. Technically wrong expansion of distribution lines (i.e., network structure is tree rather than radial)
c. Improper maintenance of distribution equipment
d. All above and more

2. For good earthing soil Resistivity should be
a. High
b. Low

3. Good earth resistance for a distribution sub-station is
a. 2 ohm
b. 20 ohm

4. Moisture improves earthing
a. Yes
b. No

5. A current of 100 MA is fatal
a. Yes
b. No

6. Sub-stations should also be provided with earthing
a. Yes
b. No

7. Closing a distribution transformer on repeated faults is a bad practice
a. Yes
b. No

8. Overloading of transformers result in technical losses and high transformer failure
a. Yes
b. No

9. What factors impede the conduct of an accurate energy audit of a distribution system?
a. Inadequate metering
b. Improper meter reading
c. Malfunctioning of meters
d. All above and more

10. Cannibalized transformer should be loaded up to
a. 52 %
b. 64 %
c. 74%
d. 80 %

11. Refurbishment of the distribution system is necessary before distribution automation can be taken up.
a. true
b. false

12. What steps can be taken to improve quality of power supply?
a. customer education on demand side management (DSM) adoption
b. refurbishing the distribution system
c. improving the distribution network system through GIS mapping
d. reducing AT&C losses
e. all above






13. In your opinion, what needs to be done as a top priority in a state utility or distribution company to improve its performance
a. Developing and implementing comprehensive training policy
b. Distribution system refurbishment
c. Customer education
d. None

14. Moisture harms transformer oil
a. Yes
b. No

a. yes
b. no

16. Do you think that the lack of proper tools for maintenance crew is the main cause of bad workmanship leading to higher distribution losses?
a. yes
b. no

17. For proper earthing, the pit should be filled with _________________.

18. The refurbishment and regular maintenance of all distribution equipment is necessary for an effective distribution automation system.
