We often take it for granted that when we flick a switch or push a button, the lights will automatically turn on, phones will recharge, and computers power up. We also expect a continuous and reliable delivery of electricity to our homes and businesses. For the most part, this is the norm. However, given the sheer size of our distribution network and the condition of our infrastructure, it is not surprising that, from time to time, things can go wrong.Equipment failures and weather conditions can play havoc with network reliability. So having up-to-date information and a high-level view of exactly what is happening on the network is crucial for distribution engineers to make informed decisions. It allows them to better prioritize aging equipment replacement, identify worst-performing circuits and understand network load behavior in order to prevent power failures and improve power quality issues.
