7.2 Application example and its connections
This chapter presents an application example for the capacitor bank protection IED.
Since two line-to-line voltages and the zero sequence voltage (U3) are connected, this application
uses the voltage measurement mode "2LL+U0" (see the image below). Additionally, the three-phase
currents are also connected. The digital inputs are connected to indicate the breaker status, while the
digital outputs are used for breaker control.
