REM615 constitutes main protection forasynchronous motors and the associated drives. Typically, the motor IED is used with circuit-breaker or contactor controlled HV motors, and contactor controlled medium sized and large LV motors in a variety of drives, such as pumps and conveyors, crushers and choppers, mixers and agitators, fans and aerators. The motor IED is thoroughly adapted for earth-fault protection. Using cable current transformers sensitive and reliable earth-fault protection can be achieved. The earth-fault protection can also utilize phase current transformers in Holmgreen...

Table 3. Supported ABB solutions ABBs 615 series protection and control IEDstogether with the COM600 Station Automation device constitute a genuine IEC 61850 solution for reliable power distribution in utility and industrial power systems. To facilitate and streamline the system engineering ABBҒs IEDs are supplied with Connectivity Packages containing a compilation of software and IED-specific information including single-line diagram templates, a full IED data model including event and parameter lists. By utilizing the Connectivity Packages the IEDs can be readily configured via the PCM600...

By default, the binary channels are set torecord external or internal IED signals, for example the start or trip signals of the IED stages, or external blocking or control signals. Binary IED signals such as a protection start or trip signal, or an external IED control signal over a binary input can be set to trigger the recording. The recorded information is stored in a non-volatile memory and can be uploaded for subsequent fault analysis. The condition monitoring functions of theIED constantly monitors the performance and the condition of the circuit breaker. The monitoring comprises the...

The IED includes fuse failure supervisionfunctionality. The fuse failure supervision detects failures between the voltage measurement circuit and the IED. The failures are detected by the negative- sequence based algorithm or by the delta voltage and delta current algorithm. Upon the detection of a failure the fuse failure supervision function activates an alarm and blocks voltage-dependent protection functions from unintended operation. The IED is equipped with three phase-current inputs, one residual-current input, three phase- voltage inputs and one residual voltage input. The...
