MService Condition Monitoring covers the following main functions:

 Collection of operational data of the supervised modules

 Collection of all alarms and trips generated in the supervised modules

 Collection of maintenance warnings derived from additional assessment logic related to the supervised modules.

 Display of the MNS or MNS iS system structure highlighting modules signaling problems

 Display of historical data in trend displays

 Detailed information on the identification, location, and type of supervised modules

 Online supervision of temperature or power loss related problems within individual cubicles.

MService can supervise all modules in MNS and MNS iS, which are connected to the internal

switchgear communication bus. 

The IED offers directional and non-directional overcurrent and thermal overload protection as

well as directional and non-directional earth-fault protection. 

Some standard configurations allow as an option admittance-based, harmonics-based or wattmetric-based earth-fault protection to be

used in addition to directional earth-fault protection. 

Further, the IED features sensitive earth-fault protection, phase discontinuity protection, transient/intermittent earth-fault protection, 

overvoltage and undervoltage protection, residual overvoltage protection, positive-sequence undervoltage 

and negativesequence overvoltage protection. 

The outstanding I/O capability in REC670 enables control of several bays with complete measurement with only one IED. 

For instance, one REC670 IED is capable of handling control of all apparatuses 

in one entire diameter in 1 ½ breaker arrangement including breaker failure protection for all breakers.
