Insulation coordination is defined as the selection of dielectric strength of equipment, taking into account the over-voltages that could appear in the utility system and with the presence of protective devices. Electromagnetic transient (EMT) over-voltages are regarded as disturbances due to lightning surges and switching surges that result in the disruption and possible damage to equipments. The principal subject of this paper is to perform insulation coordination on the distributed generation (DG) by using methods of modeling lightning surges and switching surges. PSCAD/EMTDC is the main software used for the modeling and simulations.
