Insulation monitor - GMWISO 1.05ConceptionGMWISO insulation monitors are insulation monitoring modules taking especially intoaccount the increased safety need and the current regulations for portable,combustion?engined stand?by electricpower units.Ungrounded, portable stand-by electric-power units with the optimum system ofprotection "Fuse disconneetion with insulation monitoring and cut-off" realised withthe GMWISO insulation monitor may also be commissioned by non-electricians andbe operated in areas with an increased threat to persons (for ex. damp areas).Several consumers may be connected to the stand-by electric-power generator atthe same time. A "built" and measured grounding device is not necessary. Extensiveelectricity distribution supply networks are admissible.GMWISO insulation monitors have been developed especially for the difficultoperating conditions in the case of direct mounting to portable stand-by electricpowergenerators.GMWISO insulation monitors can be supplied as individual modules for OEMs to beintegrated into newly-designed electric-power generators and as retrofitting kit forgenerators already available on the market.Product descriptionThe GMWISO insulation monitors serve for the insulation monitoring in ungroundedA.C. networks (as well as chained threephase networks in star connection) ofportable stand?by electric-power generators. With GMWISO insulation monitors, it iseasy to generate electric-power generators according to regulations (for ex.GW308, VDE 1) 0100.728) with little time needed for assembly and wiring.The distribution supply network of the stand-by electric-power generator mayinclude pure A.C. consumers as well as non-electrically separated, D.C. fed devices(for ex. frequency converter, threephase to single-phase rotary welding converter,D.C. operated solenoid valves and brakes etc.). Spurious releases due to deviceswith D.C. components connected to the generator are largely impossible because ofthe new circuit technology with automatic sign-dependant sensitivity adaptation. Itmust, however, be taken into account that faulty insulation on the D.C. side canlead to a release, but with diverging sensitivity. The threshold value indicated forthe devices for faulty insulation is valid for faults in the A.C. network. In theTechnical Data of the GMWISO insulation monitors you flind a typical threshold valueindicated for a faulty insulation on the D.C. side of the connected devices. Theindications are valid for the D.C. circuits used mostly.Regarding the threshold value and the behaviour during switch-off time GMWISOinsulation monitors have been matched with the valid regulations and are fail-safe.The stand-by electric-power units must be built according to DIN 6280, part 10, andon the altemator side laid out according to VDE 0530. They must be laid out andtested for the network structure (IT network) provided for in VDE 0100, part 728/4.2.2. with the method 4.2.4.2.1.1)*VDE = German Electric Engineers RegulationsGTS GmbH & Co.
