Insulation monitors are used to monitor the insulation resistance in unearthed IT networks. The relays detect insulation faults and earth faults in AC, DC and AC/DC networks and help prevent failures, downtime and safety risks at an early stage. This helps ensure the availability and safety of installations.
Reliable insulation monitoring
DOLD insulation monitors are suitable for industrial IT networks and, depending on the type, can be used in networks with high leakage capacitances to earth. Models are also available with adjustable alarm thresholds, self-test functions and interfaces for diagnostics and external communication.
Applications in industry
Insulation monitors are used in applications such as industrial installations, energy storage systems, machine building, charging infrastructure and critical power systems where continuous insulation monitoring is required. Thanks to their compact housing, the relays can easily be integrated into new and existing installations.
Main features of insulation monitors:
- Monitoring of insulation resistance in IT networks
- Suitable for AC, DC and AC/DC networks
- Detection of insulation and earth faults
- Adjustable alarm thresholds and self-test functions
- Available with diagnostic and communication options
- Compact design and easy integration
