Precautions Guidelines for 415V, 3Ph 4wire, 50HZ Power Distribution and Electrical HT/LT Panels :

During the summer season, Electrical HT/LT Panels endure significant stress owing to elevated temperatures. Consequently, this can result in potential hazards, including overheating, power system failure, and fire risks. Here at Accu-Panels, we emphasize the importance of implementing precautionary measures for electrical panels during summer. By diligently attending to them during this period, you can prolong the lifespan of your factory building and solar plant panels while mitigating the risk of incurring additional costs. This same steps we can follow for HVAC panel, VFD Panel, Synchronizing Panels and Fire control panels and improve life of power and control panels.

1.     Ensure proper ventilation:

Ensure that the electrical panel has adequate ventilation. Proper airflow helps dissipate heat and prevents components from overheating. Clear any obstructions around the panel that may be restricting airflow. Ensure that the ventilation fan installed in the panel is working properly.

2.     Check for Overloading:

Electricity demand often increases during the summer due to air conditioning units, fans, pool pumps and other appliances running at full capacity. Ensure that the electrical panel is not overloaded by distributing the load evenly throughout the circuit and avoiding the use of extension cords for high-powered appliances. If you are using an electric panel solar plant, keep the inverter setting at 80-90%. Confirm De-rating Factor with Switchgear manufacturer and take heat load calculation before procurement.

3.     Check for signs of wear and tear and address in time:

Inspect the LT and HT panels regularly for any signs of wear, such as frayed wires, loose connections, or corrosion. Correct any problems immediately to prevent electrical failure or fire. Contact a reputed electrical panel manufacturer nearby if possible.

4.     Keep the area clean and dry:

Maintain cleanliness around the electrical panel and keep the area dry using an air blower. Moisture can corrode components and increase the risk of short circuits. Avoid storing objects or liquids near the panels. Use IP65 approved Electrical panels for Outdoor application and IP52 for Outdoor applications. Use Overhead Canopy or Shed for Solar LT/HT panels.

5.     Install surge protection:

Install a surge protection device to protect sensitive electronic equipment from voltage spikes, which are common during summer storms, as well as from lightning damage.

6.     Monitor the temperature:

Consider installing temperature monitoring devices inside electrical panels to detect overheating early. If there is no temperature monitoring device, contact a reliable electrical panel manufacturing company like Accu-panels Energy for solar or industrial plant. If the temperature exceeds safe limits, take immediate action to resolve the problem.

7.     Schedule regular maintenance in Electrical HT/LT panels:

Arrange for a professional electrician to perform routine maintenance checks on the electrical HT/LT panels. They can identify potential problems in advance and make necessary repairs or upgrades to ensure the panels operates safely and efficiently.

8.     Educate users:

Educate plant operators or employees on electrical safety practices, such as not overloading circuits, avoiding water contact with electrical equipment, and knowing the location of circuit breakers or fuses in case of an emergency and making sure they are working properly.

9.     Invest in Professional Upgrades if Necessary:

If your electrical panels are outdated or insufficient for the current load demands, consider investing in a professional upgrade to a larger capacity electrical panel with Accu-panels make modern safety features.

10. Have Emergency Procedures in Place:

In the event of an electrical emergency, ensure that everyone knows what to do. This includes knowing how to shut off power to the panel and having emergency contact information for service support engineers or emergency services readily available.

Additional Precautions Guidelines for 800V System:

1.     Adhere to Manufacturer Guidelines:

Follow the manufacturer’s guidelines and recommendations for installation, operation, and Maintenance of the 800V solar LT panels. Adhering to 800V Solar power distribution system guidelines help ensure optimal performance and safety.

2.     Install Ground Fault Protection:

Implement ground fault protection devices to detect any leakage currents that could pose a shock hazard. Ground fault protection helps ensure the safety of personnel working on or around the solar LT panels or we can called Solar ACDB DCBD .

3.     Consider more De-Rating Factor:

Typically, the de-rating factor for 415V switchgears can sustain 30%; however, when dealing with 800V, we suggest increasing it to 40%.

Consequently, we strongly recommend Accu-panels make Solar 800V LT Panels due to their superior performance with a lower de-rating factor system and IP55 approved IEC-61439 fully type tested systems.

4.     Monitor Inverter Operation

Keep a close eye on the operation of the inverter, which converts the DC electricity generated by the solar panels into AC electricity for use in your building. Any irregularities in the inverter’s operation could indicate potential issues with the panels or wiring.

5.     Expertise and Support:

With years of experience in the industry, Accu-panels Energy provides expert guidance and support to customers throughout the entire lifecycle of their panels. From initial consultation and installation to ongoing maintenance and upgrades, their team is committed to ensuring customer satisfaction.

In conclusion, ensuring the safety and reliability of 415V and 800V LT panels during the summer season demands a comprehensive approach. Firstly, regular inspections, maintenance, and adherence to safety guidelines are imperative. Moreover, precautions such as monitoring equipment operation, checking electrical connections, and maintaining fire safety measures are crucial. These measures help minimize risks such as overheating, electrical faults, and fires. Additionally, proper training of personnel and adherence to manufacturer guidelines are essential for effective operation and longevity of the electrical distribution system. By incorporating these measures into your maintenance routine, you optimize the performance of your electrical HT and LT panels while prioritizing safety for personnel and property alike.
