Electrical safety of unearthed networks (IT systems)
VARIMETER IMD - Insulation Monitoring Device, Insulation Monitor
Insulation monitoring devices of the VARIMETER IMD (Insulation Monitoring Device) series are available for direct current (DC) as well as three-phase, alternating current (AC) and mixed systems (AC/DC) and monitor the insulation resistance in unearthed systems (IT systems). Insulation monitors thus guarantee greater operational and system safety and are used to monitor switched-off loads, mobile power generation, DC charging stations and eMobility.
Insulation monitoring at DC charging stations - standard IEC/EN 61851-23
VARIMETER EDS - Insulation fault locator, insulation fault location system
The insulation fault location system of the VARIMETER EDS family locates insulation faults quickly and reliably in complex isolated AC/DC systems (IT systems).An insulation fault location device, also called IFLS (Insulation Fault Location System), enables insulation faults to be located quickly in unearthed power supply systems.
Electrical safety of grounded power systems (TN systems)
VARIMETER RCM - Residual current monitoring, residual current monitors
Residual current monitors of the VARIMETER RCM (Residual Current Monitor) series ensure reliable residual current monitoring of grounded power supplies (TT and TN systems). The residual current monitors are universally applicable, as they are available as standard version for direct current or pulsating direct current (DC) systems, as well as an all-current sensitive version for mixed systems (AD/DC). The differential current measurement is carried out via an external differential current transformer (current transformer).
Periodic inspection according to DGUV regulation 3 (BGV A3)

Electrical safety of annunciators
INFOMASTER - Fault indicators
Annunciators and annunciator systems enable efficient monitoring and control of machines and systems in industrial and building automation. Especially when using PLC or control system technology, it is essential to install a fault detection system independent of the process level, so that control is not lost in the event of a failure of the plant control system, which could lead to damage.
