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.
