Device ISOP M – mechanical indicator

The beginnings of the RAM-1 device date back to 2014. As a manufacturer of surge arresters, the problem of efficiently determining the condition of surge arresters in the electrical distribution and transmission networks is well known to us. Therefore we decided to develop a device that immediately indicates the degradation of the built-in arrester in…
