7.2 Application example and its connections
This chapter presents an application example for the feeder 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 and the residual current (I01) are also connected. The digital inputs are connected to indicate
the breaker status, while the digital outputs are used for breaker control.
