The devices allow insulation monitoring to earth of out-voltage networks in order to carry out a preventive monitoring on insulation level of device.
Preventive monitoring is really important in case of applications which are not used permanently (for example: motors, fire-engines, and so on). In these applications, humidity and condensate can cause a serious decrease in insulation’s level and obstruct correct functioning at the moment of applications’ activation.
