Streets® draws on Safearth’s decades of experience in earthing design, software development and earthing testing. It solves the thorny problem of producing safe distribution designs without employing complex, costly multipurpose earthing design tools or using “free” tools with limited accuracy and capability—often based on formulaic empirical approximations rather than a proven analytical calculation engine.
Producing risk-based distribution earthing designs can be tricky and time-consuming. People living all around electrical assets need to be kept safe during earth fault events, but design budgets are usually very limited and the earthing system must be affordable to build. All this puts a lot of pressure on the earthing designer.
Streets design software has been developed to address this very problem. This simple but extremely powerful tool enables designers to explore the available options and develop the best solution as quickly as possible, in order to meet the relevant Australian Standards.

Complex design tools are usually expensive to buy, maintain and train staff in their correct use. Producing distribution earthing designs that model the surrounding MEN (Multiple Earth Neutral) and earthing interconnections is very time-consuming in such tools as they provide great flexibility but also require significant data input, which can dramatically increase the cost of accurate earthing design.
Free tools often rely on modelling approximations, which can lead to unnecessarily conservative earthing designs which are costly to build or designs with significantly higher risk than indicated by the tools. In addition, they are often accompanied by lots of procedures to manage cases the software can’t handle.
