The Roles of T&D Companies

• Deliver comfort and convenience to customers at affordable tariff rate

• Powering the economy of the country, state, city served


Common Challenges Faced by Most Utilities

• Inadequate capital

for strengthening the

network

• Mindset problems


Inadequate Capital?

Preventing equipment failures will save capital fund


Termination Failure Unable to Find the Root Causes


21

Changing The Mindset

Key Challenges:

•Inherited Culture

•Historical Experience

•Perception of Norms

•Exposure

Unlearning and Relearning


22

The People

Quality Workforce:

• Dedication

• Knowledgeable

• Professionalism

• Openness

• Willingness

Network Planning

• Planning Guidelines and

Criteria

– No overloading

– Available alternative

– Simple to operate

• Other Consideration

– Planned Network Redundancy

– Spare capacity for load growth

– Flexibility for network

expansion


Network Construction

• Quality Management System

– Contractor workers registration system

– Contractor workers training

– Enforcement for using proper tools

• Doing Things First Time Right

– No repeating of same known mistakes

– Root cause analysis

– Information sharing and education

• Five Years Warranty


Evolution of Maintenance Practices

• Post-Fault Repairs

• Preventive

• Predictive

• Condition-Based

Historical

New

Approach


Condition-Based Maintenance


Maintenance Policy

Time-based Maintenance

OEM Recommendation

• Combination of scheduled

periodic and condition-based

maintenance

• Leverage condition results to

fine-tune maintenance cycles

Adoption of Condition-based

Maintenance Regime

Benefits of Condition Monitoring

• Learning will form basis for a long-term Condition Monitoring

program

Higher Reliability of Network

Cost Savings

More Effective Maintenance

Policy

Safer Working Environment

Condition Monitoring


• Preserving reliability and quality

of supply

• Less faults to weaken network

• Short downtime

• Rectification cost is much

cheaper than repair cost

• Evidence of root cause

not destroyed
