What Principles Should Be Followed When Troubleshooting Rural Lighting Electrical Ready Boards In Africa? Simple First, Then Complex. Check The Lighting Fixtures First, And Then Check The Wiring And Switches?
Principles for troubleshooting rural lighting electrical ready boards in Africa
The troubleshooting of rural lighting electrical ready boards in Africa must strictly follow the core principles of external to internal, simple to complex, static to dynamic, and load to body, and adapt to the on-site environment of unstable power supply, frequent thunderstorms, old lines, and limited operation and maintenance conditions in rural areas. The troubleshooting sequence is not to first inspect the lighting fixtures and then the circuit switches. The correct process should start with the intuitive and simple parts: first, check the external visual faults, visually inspect the box for damage, screw rust, aging insulation of incoming and outgoing lines, loose and burnt joints, tripping of leakage protection devices and other obvious problems, and quickly make a preliminary judgment without dismantling the machine. Next, check the end load lamps first, disconnect the lighting lamps and socket loads one by one, distinguish whether it is a single lamp fault or an overall circuit fault, and eliminate the tripping caused by load short circuit or burnout. Next, check the branch lines and control switches, sequentially inspect the air switch, leakage protector, and wiring terminals for overheating, disconnection, and poor contact, and verify whether the lines are improperly connected or leaking due to rainwater and moisture. Finally, go deep inside the electrical ready board box to inspect the busbar, grounding, SPD lightning protection devices, circuit wiring, and aging of components. Throughout the process, we adhere to not blindly dismantling the machine, cutting off power before testing, prioritizing the elimination of simple and intuitive faults, and then dealing with complex internal component problems. This can not only improve the efficiency of troubleshooting, but also avoid electric shock and short circuit safety hazards caused by thunderstorm weather and old lines, and meet the practical needs of rural operation and maintenance in Africa.
