   • Create a detailed report on maintenance results, including identified issues and actions taken. This is an important step in the maintenance system reporting process.
   • Propose improvements for the next maintenance process.
7. Training and Upgrading
   • Ensure maintenance staff are fully trained in technical skills and safety.
   • Keep staff continuously updated with skills.

During periodic electrical maintenance, technicians should strictly adhere to safety regulations and use personal protective equipment to ensure safety for both staff and the electrical system. This detailed electrical system maintenance process not only helps the system operate better but also prevents unwanted incidents.

Notes on Electrical System Maintenance

In factory electrical system maintenance, anticipate potential problems to have timely repair solutions. Preparing emergency supplies and machinery is essential. Building plans for system upgrades or conversions to meet new requirements and improve performance should also be prioritized. Adequate staff training on techniques and factory electrical safety ensures effective and safe operations.

Electrical system maintenance is indispensable to ensure effective factory operations. For proper maintenance, engineers need to execute the important steps below.

Assessing Fault Causes and Preparing Techniques

1. Before maintenance, determining the source of the problem is very necessary. This includes checking for leakage current, short circuits, or overload conditions.
2. Fully disconnect electricity in the maintenance area to avoid risks, and isolate staff from that area.
3. Use protective equipment such as insulated gloves, safety shoes, and measurement equipment to ensure safety.

Electrical System Inspection

• Monitor and assess temperature and vibration of equipment to detect overheating and damage phenomena.
• Thoroughly inspect wiring and connections to avoid phenomena such as oxidation, looseness, or disconnections.
• Use measuring devices to check insulation resistance and identify leakage currents to ensure technical safety.

Cleaning and Maintenance

• Remove contaminants such as dust and grease on equipment to prevent fire hazards.
• Lubricate mechanical parts such as CBs, contactors to reduce friction and extend lifespan.
• Inspect the surrounding environment including humidity and temperature to avoid affecting equipment efficiency.

Replacement and Upgrading

• Priority replacement of damaged components with IEC or TCVN standard products to ensure safety and efficiency.
• Record detailed faults detected along with solutions to optimize maintenance schedules for the future.
• Update existing monitoring software to enhance accuracy in fault detection and handling.

Safety and Compliance

• Strictly adhere to regulations on safe distances when working with high voltage electricity.
• Before operation, conduct no-load testing to ensure safety.
• Thoroughly and regularly train staff on new techniques and how to handle emergencies.

Special Notes

• Avoid using homemade devices to minimize risks during repairs.
• Ensure backup systems are arranged so that critical equipment can operate without interruption.
• Conduct lightning protection and grounding system checks at least every 6 months to maintain effectiveness.

Maintaining these systems requires high skill and thorough preparation not only to prevent potential failures but also to ensure smooth operation and cost savings.

Application of New Technology and the Future of Factory Electrical Systems

The application of new technologies like IoT in monitoring and analyzing the performance of factory electrical systems helps improve the maintenance process. It’s time to consider transitioning to renewable energy sources to reduce environmental impact and long-term costs.

New technology applications are central to the transformation of factory electrical systems. With the advent of flexible solutions, there is an opportunity to optimize both cost and environmental efficiency.

Flexible Electrical Technology

According to research from Wärtsilä (2024), applying flexible power plants in integrated renewable energy systems could save up to €65 trillion by 2050. These plants allow for rapid capacity adjustment to stabilize the grid, reducing the need for new renewable energy installations by half and occupying less space.

An important electric technology solution is the real-time coordination system, where high-speed control technologies ensure renewable energy equipment like solar panels is synchronized with storage systems (BESS) to maintain stable current/voltage.

Virtual Power Plant and the Smart Grid

Virtual Power Plant (VPP) integrates multiple distributed sources like rooftop solar energy, storage battery systems, and controllable loads to optimize supply-demand balance. VPP allows for fast-response services through controlling electric vehicle charging times or supplying reserve power at peak demand. This system also uses historical data to forecast renewable energy output and optimize energy sources in real-time.

Industry 4.0 in Operational Management

IoT and automatic monitoring systems provide superior connectivity and data analysis capabilities in electrical systems. IoT sensors collect voltage and load current parameters, transmitting them to the control center for analysis using big data analytics. System modeling helps evaluate and plan before actual deployment.
