Common Faults In Rural Lighting Electrical Ready Boards In Africa
The poor power supply environment, large voltage fluctuations, and rudimentary construction wiring in rural Africa have led to a high incidence of lighting electrical Ready Board Box failures, mainly concentrated in five categories: loose wiring, short circuits, leakage, circuit breakers tripping without reason, and damaged components.
Loose wiring is the most frequent fault. In rural areas, the wiring process is rough, and there is long-term temperature difference vibration. In addition, the poor sealing of the box can cause sand and dust to enter. The wiring terminals are prone to oxidation and loosening, resulting in heating, sparking, flickering lights, and in severe cases, burning of the terminal block.
Short circuits are often caused by aging and insulation damage of the circuit, external scratching of outdoor cables, and rainwater infiltration into the box, resulting in phase to phase or ground short circuits. Instantaneous current surges can easily burn out the circuit and distribution components.
Leakage is mainly caused by humid environment, water ingress into the box, weathering and cracking of the cable insulation layer, as well as the unauthorized connection of loads by farmers, resulting in the shell being charged and the leakage protector frequently operating, posing a great safety hazard of electric shock.
Circuit breakers trip due to overload and false tripping caused by faults. Farmers arbitrarily install high-power lamps with excessive loads, or voltage surges or lightning induced voltage surges, resulting in frequent tripping of circuit breakers and inability to close normally.
Component damage is most affected by high temperature exposure, lightning surges, and unstable voltage. Leakage protectors, circuit breakers, wiring terminals, and electricity meters are prone to aging and failure, resulting in refusal to operate, misoperation, and poor contact, directly causing power outages for the entire village's lighting.
