6 Application Examples - Ungrounded Monitoring Insulation monitoring of primary distribution system with IRDH375 – Insulation monitoring of secondary distribution system with IR1575 Interconnected ungrounded systems Many ungrounded systems onboard ships and platforms with have systems interconnected via a tiebreaker. Depending on the system's operation, this tieberaker may be open or closed. BENDER's ground detectors allow for either automatic or manual control of the detectors' operation to ensure that only one device is active on a circuit at one time.
Offline Monitoring A-ISOMETER® IR420-D6 Offline monitoring with IR420-D6 Offline monitoring with IR420-D6 n Provides safe monitoring of electrical insulation integrity in cer tain installations n Monitors the insulation resistance of de-energised TN, TT and IT systems, e. g. fire extinguisher pumps, slide-valve drives, standby generators, deck machinery in offshore platforms and marine environment n Gives early warning of insulation degradation, before motors (or generators) with deteriorated insulation are in immediate danger of failing on start up n Early warning for preventive maintenance to be scheduled when convenient n Eliminates failure and the need for an emergency replacement or rewind n Two separate response values 100 kΩ…10 MΩ 7
