VARIMETER EDS Insulation fault location system Precise localisation of faults during operation In extensive industrial systems, the localisation of insulation faults can be a costintensive and time-consuming process.The VARIMETER EDS family of insulation fault location systems from DOLD, comprising the RR 5886 test current generator and the RR 5887 insulation fault location device, localise insulation faults quickly and reliably in complex insulated AC/DC networks (IT systems). A device for insulation fault detection, also known as IFLS (Insulation Fault Location System), enables the rapid localisation of insulation faults in non-earthed power supply systems. It is employed along with an insulation monitor and in the event of a fault it injects a test current between the current-carrying conductors and the earth. It allows the quickest possible localisation of components with pre-existing insulation damage so that they can be replaced before a complete failure occurs. Protective devices such as circuit breakers or fuses only trip after a second fault. Immediate fault rectification is therefore required. During operation you receive all necessary information regarding faulty circuits and consumer outputs, which can be visualised directly on the RR 5887 insulation fault detection device. This allows the optimum planning of the maintenance and repair of your system.VARIMETER EDS is suitable for use in a great variety of sectors. Your advantages Automatic and rapid localisation of faulty circuits Increase in reliability and system availability Optimum planning of the maintenance and repair No manual and time-consuming fault detection Simple operation Monitoring of complex systems
