Devices and Systems for Insulation Deterioration Alarming
In the chapter few traditional methods of insulation monitoring in DC networks are presented. The simplest system of insulation condition visual supervision consisted of two bulbs. System of insulation monitoring comprising two undervoltage relays RV is analyzed. Another system of signaling of insulation level deterioration based on voltage criteria is shown. Commonly applied monitoring systems based on a bridge circuit are described. An example of application of the bridge measuring method is presented.
