• Page 32 2.3.1 Description A facility is provided in the P341 to maintain correct operation of all the protection functions even when the generator is running in a reverse phase sequence. This is achieved through user configurable settings available for the four setting groups.
• Page 33 (Vbc, Vca, Vab) is reversed by the change in phase rotation. Note, CT2 is not applicable to P341/2 relays only P343/4/5 relays which include differential protection. The relationship between voltages and currents from CT1 for the standard phase rotation and reverse phase rotation are as shown below.
• Page 34 P341/EN AD/F43 Update Documentation (AD) -30 MiCOM P341 The Phase Sequence setting applies to a power system that has a permanent phase sequence of either ABC or ACB. It is also applicable for temporary phase reversal which affects all the VTs and CTs. As distinct from the other phase reversal settings, this setting does not perform any internal phase swapping of the analogue channels.
• Page 35 LED’s etc. The complete list of these signals may be found by viewing the available settings in the relay menu or via a setting file in MiCOM S1. Any of the digital channels may be selected to trigger the disturbance recorder on either a low to high or a..
• Page 36 (e.g. relay 3) will trigger the recorder. It is not possible to view the disturbance records locally via the LCD; they must be extracted using suitable software such as MiCOM S1. This process is fully explained in SCADA Communications (P341/EN SC).
• Page 37 Update Documentation P341/EN AD/F43 MiCOM P341 (AD) -33 In the default PSL, Relay 3 is still mapped to the “Any Trip” DDB and the “Fault REC TRIG” DDB signals. If the user wants to make use of the CB maintenance features, CB failure function etc.

LocalTime Enable Fixed Disabled/Fixed/ Flexible Setting to turn on/off local time adjustments. Disabled - No local time zone will be maintained. Time synchronization from any interface will be used to directly set the master clock and all displayed (or read) times on all interfaces will be based on the master clock with no adjustment.
• Page 39 NIT/TIA often specified historically. The table below recommends advisory limits on relays connected per fused spur. This applies to MiCOM Px40 series devices with hardware suffix C and higher, as these have inrush current limitation on switch-on, to conserve the fuse-link.
• Page 40 ALSTOM Grid Automation's offer of a full IEC 61850 solution for the substation. The majority of MiCOM Px3x and Px4x relay types can be supplied with Ethernet, in addition to traditional serial protocols. Relays which have already been delivered with UCA2.0 on Ethernet can be easily upgraded to IEC 61850.
• Page 41 Update Documentation P341/EN AD/F43 MiCOM P341 (AD) -37 9.2.2 The data model To ease understanding, the data model of any IEC 61850 IED can be viewed as a hierarchy of information. The categories and naming of this information is standardized in the IEC 61850 specification.
• Page 42 Logical Node type XCBR. IEC 61850 in MiCOM relays IEC 61850 is implemented in MiCOM relays by use of a separate Ethernet card. This card manages the majority of the IEC 61850 implementation and data transfer to avoid any impact on the performance of the protection.
• Page 43 In order to keep this process as simple as possible, such setting changes are done using MiCOM S1 Settings & Records program. This can be done as previously using the front port serial connection of the relay, or now optionally over the Ethernet link if preferred (this is known as “tunneling”).
• Page 44 The relay can be configured to accept data from networks other than the local network by using the ‘Gateway’ setting. The data model of MiCOM relays The data model naming adopted in the Px30 and Px40 relays has been standardized for consistency.
• Page 45 32 virtual inputs within the PSL. The virtual inputs allow the mapping to internal logic functions for protection control, directly to output contacts or LEDs for monitoring. The MiCOM relay can subscribe to all GOOSE messages but only the following data types can be decoded and mapped to a virtual input: ..

All GOOSE publishing configuration can be found under the ‘GOOSE Publishing’ tab in the configuration editor window. All GOOSE subscription configuration can be found under the ‘External Binding’..
• Page 47 Not used Not used Table 4: Signals on the Ethernet connector RELAY DESCRIPTION (P341/EN HW/F33) 1.1.6. Ethernet board This is a mandatory board for IEC 61850 enabled relays. It provides network connectivity through either copper or fiber media at rates of 10Mb/s (copper only) or 100Mb/s. There is also an option on this board to specify IRIG-B port (modulated or un-modulated).
• Page 48 High break relay board One ‘high break’ output relay board consisting of four normally open output contacts is available for the P341 as an option. This board contains a hybrid of MOSFET solid state devices (SSD) in parallel with high capacity relay output contacts.
• Page 49 In traditional hardwired scheme designs, high break capability could only be achieved using external electromechanical trip relays. External MVAJ tripping relays can be used or the new high break contacts inside MiCOM relays can be used – reducing panel space. 2) Accessibility of CB auxiliary contacts Common practice is to use circuit breaker 52a (CB Closed) auxiliary contacts to break the trip coil current on breaker opening, thus easing the duty on the protection contacts.
• Page 50 MiCOM high break contacts will avoid the risk of burnt relay contacts. 4) Initiation of teleprotection The MiCOM high break contacts also offer fast making. This can provide faster tripping: additionally, fast keying of teleprotection is a benefit. Fast keying bypasses the usual contact operation time, such that permissive, blocking and intertrip commands can be routed faster.
