Online Relay Coordination & Protection Engineering
RelayCoordination.com provides web-based tools for exploring protection coordination, relay operation times and associated engineering studies.
Relay characteristics
Explore overcurrent and earth-fault settings, IDMT curves, definite-time operation and time-current coordination.
System representation
Study protection behavior against the single-line diagram, equipment hierarchy and selected fault locations.
Engineering outputs
Plot TCC curves, simulate faults and prepare engineering reports and exportable study outputs.
Who the tools are for
Electrical engineers, protection engineers, commissioning teams and technical learners working on power-system protection studies.
The software is a support tool for engineering analysis, not a substitute for verified protection settings, plant design data, manufacturer guidance, safety procedures or approved studies.
