Safety protocols and best practices in power distribution

Electric power distribution is a complex domain where the safety of workers and the reliability of the power supply system are of utmost importance. The transmission and distribution of electrical power include risks such as electrical shocks and system failures. To ensure a robust power distribution system, safety protocols and best practices play an important role. Here, we discuss some of the useful insights on critical safety measures necessary to protect workers and maintain a reliable power supply:

1. General safety:

• Training and certification: Only workers who undergo proper training and certification should be cleared to work on electrical power distribution system.
• Lockout/Tagout (LOTO): LOTO procedures are important not only for the protection of workers but also to maintain the integrity of the power distribution system.When multiple workers are involved in maintenance, a "group LOTO" procedure is used. Each worker applies their own lock to the isolating devices, ensuring everyone has control over the re-energization process.
• Personal protective equipment (PPE): When working with live wires and other components of the power distribution system, workers must wear appropriate personal protective equipment (PPE) to ensure their safety.

2. Equipment safety:

• Regular maintenance and inspections: Predictive maintenance schedules have to be established to address issues before they escalate.
• Grounding and earthing: Grounding is a safety technique that's important for both protecting people and keeping electrical equipment safe. It works by creating a direct path for electrical current to flow into the ground in case of a fault, like a short circuit.

3. Work practices:

• Planning and risk assessment: Before working on power distribution systems, planning and assessment of potential hazards is important. The plan should outline ways of reducing specific risks.
• Working on de-energized equipment: It's the safest method. However, it may not always be feasible, and in such cases, stringent safety measures must be adhered to.
