I need P740 Topology Tools

[Aakbar]

Hi, recently we have purchased P741 and P743 for decentralised busbar protection and in order to configure the relays i need "Scheme Editor" and "Synaptic Tool".

As in latest revision of Easergy Studio only two tools are provided which are Dynamic synaptic and File Merger whereas the former two are essentially required for configuration of relays. Please provide the tools.

Busbar Topology Software required 

Micom S1 Studo software upgrade to latest Easergy studio

Hello,

As stated in https://community.se.com/t5/Protection-Control/Rules-for-MiCOM-P740-Busbar-protection/m-p/170215 only P740 competency center teams can engineer a P740.

The list of P740 competency centers are available at:

https://community.se.com/t5/PAE-Protection-Relays-Controllers/MiCOM-P740-Busbar-protection-Competenc...

If you wish to create a P740 competency center, please send a request to me by mail.

Hi,

Yes the CT ratio are defined in the peripheral units P742 or P743, then the primary values are published to central unit P741. Central unit uses only the primary values to calculate the differential current and to compare to threshold..
So the central unit does not require any change when you update the CT ratio in a P742 / P743
