Kaduna Electric says power networks in most parts of Nigeria are being faced with disruptions during rainy weather conditions leaving consumers without light.
These issues especially when it rains could be a result of electricity networks in most parts of the country being of the overhead type, which they are exposed to severe weather conditions like rainstorms and strong winds, and vulnerability to the likelihood of disruptions when adverse weather strikes.
A statement by the Head, Engineering Service, Kaduna Electric, Engr Isa Ahmed laments that strong winds can carry as much as tree branches or conductoring materials, that come into contact with the power lines.
It explains that when these materials bridge two or more phases of an 11kV or 33kV line, a fault occurs, causing the line to trip to safeguard the power transformer supplying electricity to a particular area.
“The severity of the fault is assessed using specialized devices, which guide the operator in determining whether the line can be restored or requires further attention“.
“Presence of weak insulators usually made of porcelain, may appear sound and functional during dry weather conditions. However, when exposed to rainwater, they can become conductive and ground the power line, triggering a trip at the source and, detecting these weak insulators is challenging, as their weakness is not visually evident during routine inspections. Hence, they often go undetected until power is restored and disruptions persist” the statement also laments.
It however, assured consumers that Kaduna Electric is working on ensuring effective power supply in it’s areas of jurisdictions.
