The Smart Grid Building Block

When compared with electricity distribution grids across the world, Australian Distribution Network Service Providers (DNSPs) operate in some of the most challenging environments.

Australian Switchgear Engineering Firm NOJA Power in partnership with their Swedish Distributor Techinova have successfully achieved a Smart Grid rollout project near the town of Kisa in Sweden.

Portable Algorithm Development deployed in Distributed Automatic Circuit Reclosers

Fault Passage Indication is the use of a protection asset to flag whether a network parameter excursion (current, voltage, frequency or a combination thereof) was detected at a node in the distribution network. Typically, a pickup level is set, with a short hysteresis operating time, to set a flag for possible fault passage through a node.

Providing Selectivity of SEF Protection for High Impedance Faults and Compensated Neutral Networks

SEL has released several important enhancements to the SEL-FT50 Fault Transmitter, making the SEL-FT50 and SEL-FR12 Fault Transmitter and Receiver System even more accurate in detecting faults, more power-efficient, and easier to install.

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.
