Vigilohm permanent insulation monitors from Schneider Electric on One-Elec
On One-Elec, we offer permanent insulation monitors from Schneider Electric's Vigilohm range. Vigilohm provides continuous monitoring of the insulation resistance between active conductors and earth, enabling the detection of insulation faults such as accidental earthing and current leakage.
These devices also feature configurable alarms and thresholds, allowing you to set customised alert levels for insulation resistance, triggering visual or audible alarms if they are exceeded.
Some models incorporate a C capacitance measurement function, useful for identifying capacitive faults. Equipped with a local display, Vigilohm meters show the insulation resistance in real time, making on-site monitoring easier.
For remote management, communication options such as RS485 or Ethernet are available on certain models, enabling them to be integrated into wider energy management systems.
Finally, their compatibility with generators makes them invaluable tools for ensuring continuity of power supply in the event of insulation problems.
