Capacitor energisiations lead to high frequency inrush currents and subsequent voltage increases. The latest issue P28 gives envelopes that voltage rises must stay within. Check out our paper to see the analysis across a range of sizes and fault levels.

Once the site and upstream protection devices are fully modelled we go through an iterative process with the settings. The ETAP interface allows for the curves to be minipulated in real-time, but we also use hand calculations. Check out the full report buff.ly/3jac5QA

With our growing Power System Studies department, we're proud to announce the well deserved promotion to our Senior Electrical Engineer, Kerim Ozer and our recruitment push to grow the department due to increased demand.

We use #PSCAD™ to model the #ShuntReactor, #CircuitBreaker and connecting #cables. The significant elements of this section of the model were the cable #capacitances, stray #capacitances and equivalent reactor model. The full paper can be found here - buff.ly/39XZA6K

We investigated a number of different start up methods for motors. These included Soft Starters, Slip Ring #Motors and Variable #Frequency #Drives. Check out the paper to see how they performed and which did the best in terms of voltage dip mitigation - buff.ly/31WsPmO
