Category five – Best solution to an identified electrical safety issue
NOJA Power designs, manufactures and supplies medium voltage pole mounted switchgear, specialising in auto reclosing circuit breakers for electricity distribution utilities. NOJA is continually researching and developing alternative ways of operating its equipment safely, using the latest technology.
NOJA developed a range of iPhone and Android apps to allow remote control of switchgear from the ground. This eliminated the need for power utility linesmen to climb poles in poor weather to operate equipment using microprocessor-based control cubicles and HMI control panels.
The apps provide control and interrogation capability when a USB – WiFi router accessory is fitted to the switchgear. When electrical utility linesmen are connected via WiFi, they are able to view data—such as voltage, current, power and energy levels—in real time. Linesmen are also able to monitor and control the most commonly used functions of the switchgear without the need to be in direct contact with the equipment or to work at height.
Feedback received from workers and customers confirms the apps are a safe and reliable method of operating switchgears.
