4- Shunt RLCIn PowerFactory, shunt element of LC has been combined into one RLC diagram with external grounded.We can chose shunt type which is represent of shunt configurations in substation.

5- Surge ArresterMetal Oxide Surge Arresters is used to reduce the Basic Insulation Level (BIL) required for electrical equipment by limiting the transient overvoltage draining the lightning current to ground.Protection characteristics is defined by a high non-linear residual voltage-discharge current curve.

7- LoadGeneral Load has been modeled as Inductive load, which calculated from rate power consumption at point voltage and power factor of the load.Load is modeled as source with only impedance no ideal source.
