Benefits to society at large: 1) PRICE of electricity. Reduces electricity losses due to faulty surge arresters (surge arresters protect power grids) – there is an estimation that around 2% of electricity is lost due to faulty surge arresters used in power grids. The lost electricity can be compared to the water lost piping system.…
