Superiority
Real-time monitoring of IT systems insulation failure,
High precision, low error, fast response
Wide range, true RMS measurement of insulation resistance
Fault line monitoring and positioning, and reduce the query time to discover failure to excellent performance, greatly improve the safe operation of IT systems.
Applications
Vigilohm insulation monitoring device can be preset value of insulation resistance of the insulation on the level of IT power distribution system for continuous monitoring, when the system insulation level lower than the preset threshold when the alarm signal to prevent the system insulation level decreased, but not be aware of caused by power interruption. Detection and indicating system of insulation and fault level
Accurate location automatically or manually.
Insulation resistance measurements, instantaneous fault indication,
Insulation level below the preset threshold alarm when the user
For hospitals, ships, mine the IT earthing system
Vigilohm with superior computer or PLC to communicate. Vigilohm run from inverter, UPS and switching power supplies generate harmonic effect.
