RTU and Gateway Selection for Multi-Vendor MV Switchgear Projects
A procurement and acceptance framework for multi-vendor RTUs and gateways covering IEC 61850, IEC 104, DNP3, Modbus, sizing and failover.
Category SCADA & Automation
Substation control, gateways, RTUs, protocols, time synchronisation, alarm/event design, remote operation and SCADA integration for switchgear.
Sequence-of-Events Resolution and Time Synchronization for Fault Analysis
A rigorous guide separating timestamp resolution from physical-event accuracy and proving event order, time quality, holdover and fault-record correlation.
SCADA Permissives, Interlocks and Blocking: Where Logic Should Reside
A practical cause-and-effect method for placing MV switchgear logic where speed, safety, availability, failure containment and testability require it.
Local, Remote and Supervisory Control Authority: Safe Mode Selection
A practical authority-state design for MV switchgear that prevents competing commands and safely handles mode changes, stale data, failures and maintenance.
Select-Before-Operate Versus Direct Operate for MV Remote Control
A consequence-based guide to selecting and testing direct or select-before-operate control for breakers, disconnectors, earthing switches and automation.
Building a Complete SCADA Point List and Signal Database for MV Switchgear
A field-by-field design and QA method for an MV switchgear point database that traces physical sources through IEDs, gateways, HMI and control center.
