Introduction Global concentration on Distributed Generation (DG) is increasing. This is certain because of the increase in demand for the energy every year. The targets set by the government of Great Britain in increasing the usage of renewable sources in producing electricity and at the same time to reduce the greenhouse gases emission gave boost for the further development of DG. In order to maintain the reliability of the existing switchgear, DG is used. DG helps in maintaining the voltage levels, improving power quality and to reduce the losses in the network. Having many advantages the DG’s of different types and sizes are developed to connect to the distribution networks. Distribution networks have conventional protection topologies. The range of values or the ratings of the protective devices, lines may or may not withstand the connection of DG. Connection of DG to the distribution network meets the demand and reliability conditions along with the tendency of introducing fault currents. If the fault current increases more than the fault level design limits of the network then there is chance for the malfunctioning or damage to the equipment and loss of life and property. In order to avoid the above said disasters proper protection review should be carried out before the DG is connected to the distribution network. The conclusions of the protection review sometimes leads to the employment of cost effective and reliable methods in limiting the fault current. The focus on fault current limiters helps in the connection of Distributed Generation to the distribution networks, which eventually results in the enjoyment of advantages of DG through engineering [1, 4].
