LINETRAXX® RCMS460-L Blindspot®
- Multi-channel ground-fault monitoring relay for grounded and high-resistance-grounded AC/DC systems
- Monitor up to twelve separate channels with individually adjustable alarm trip values
- Digital display with real-time readings and on-board menu
- Harmonics analysis and selectable filtering options
- Contact outputs and compatibility with Ethernet and Modbus communication gateways
The RCMS system consists of one or more RCMS460-D/-L or RCMS490-D/-L ground-fault monitors, which are able to detect and evaluate fault, residual and operating currents in grounded power supplies via the related measuring current transformers. The maximum voltage of the system to be monitored depends on the nominal insulation voltage of the measuring current transformer used in the case of busbar systems, resp. depend on the cables or conductors that are routed through.
Closed W…AB series measuring current transformers are required to measure AC/DC sensitive residual currents (according to IEC/TR 60755: Type B). Six W…AB series measuring current transformers require one AN420 or AN110 power supply unit. W (closed), WR (rectangular), WS (split-core) and WF… (flexible) series measuring current transformers are used for alternating and pulsating currents (according to IEC/TR 60755: Type A). Any combination of the various measuring current transformer series can be connected to the monitor measuring channels. Each RCMS460-D/-L and RCMS490-D/-L has 12 measuring channels. Up to 90 ground-fault monitors can be connected via a BMS bus (RS-485 interface with BMS protocol), thereby up to 1080 measuring channels (sub-circuits) can be monitored. If this product is to be used for personnel, fire or plant protection, the frequency response can be set accordingly. The measured currents can be analyzed for harmonics.
