Insulation monitor - GMWISO 1.05 - gts generator. technik. systeme.

Insulation monitor - GMWISO 1.05− Before insulation or voltage tests are carried out at the stand-by electric-powergenerators (for example in the case of high-voltage tests/earth contact tests) orat parts of the installation, the GMWISO insulation monitor must be separatedfrom the generator and all parts of the installation for the duration of the test.− In each electrically connected distribution system only one insulation monitor maybe connected (i. e. in the case of an insulation monitoring with GMWISOinsulation monitor at the generator, socalled "Solid-rubber distributors" or similarwith insulation monitor are not admissible!) because insulation monitors can havean influence on each other.− It is possible to connect D.C. powered devices (solenoid valves, brakes,converters etc.) in the network of the stand-by electric-power generator to bemonitored. It must be taken into account, however, that faulty insulation in theD.C. circuit is registered with an increased sensitivity in both current directions.− Distributions and devices with built-in residual current operated devices are notfail-safe with ungrounded, portable stand-by electric-power generators (due tothe missing grounding installation/potential segregation), but they are notnecessary when the system of protection "potential segregation with insulationmonitoring and cut-off" is used.− If the GMWISO insulation monitor is used within the scope of GW308 a briefoperator's guide for the insulation monitoring must be attached at the stand-byelectric-power generator pointing out the daily functional test.− Further inforination and regulations for the use of generators with the system ofprotection "Fuse disconnection with insulation monitoring and cut-off" can befound in VDE 0 100, part 728 and GW 308.− Additional provisions or regulations limiting the operation of the generator in thecase of particular operating conditions (for ex. rules for prevention of accidents/VBG, VDE 0706, conditions by the (German) employer's liability insuranceassociation or similar) must be taken into account.6GTS GmbH & Co.
