The earth-fault indicator type TERRA can be used in radial medium voltage networks with one input and open-ring networks. The network has to be solidly earthed or low resistance-earthed.

Network proliferation of distributed generation and renewable sources provides a new source of technical challenge for utility engineers and distribution network service providers (DNSPs). The traditional models of network performance are confined to performance domain of low harmonic sinusoids, modelling the traditional synchronous generator power flow methods for design and monitoring of a network.
