Many facility managers are surprised when an earth pit that tested well during the rains gives a much higher reading a few months later. It is not a faulty meter. Soil resistance changes with moisture, and in Nigeria the difference between the rainy and dry seasons can be large. Earthing designed only on a wet-season […]
Almost every building in Nigeria needs to switch between grid supply and a generator. The device that does this, a changeover switch or an automatic transfer switch (ATS), is one of the most important parts of the installation. Get it wrong and you risk damaged equipment, a back-feed into the DisCo network, or a generator […]
When an underground cable fails, the supply to a building, estate or factory can go off for days. The old approach was to dig along the cable route until the damage was found. In a city like Lagos, where cables run under roads, paved compounds and other people’s property, that is slow, expensive and disruptive. […]
When a transformer trips on a fault, gets flooded, or sits out of service for months, the pressure to switch it back on is enormous. Production is stopped, tenants are complaining and the generator is burning diesel. But energising a damaged transformer can turn a repairable fault into a total loss, and in the worst […]
There is a common temptation when managing facility projects or electrical installations — cut costs by going with the cheapest option available. It seems like a smart financial decision at the time. But what happens when that decision comes back to haunt you months or even years later? At Corustar Technological Services, we recently carried […]
