Protection Scheme Verification

We provide comprehensive verification of complete protection schemes, ensuring the integrity of signal chains from individual relays to end-to-end IEC 61850 networks.

End-to-End Signal Chain

Verification of complete protection schemes, including CT/VT secondary circuits, trip and close circuits, and breaker interaction logic.

IED & Digital Substation Testing

Comprehensive testing of IEDs, IEC 61850 systems, GOOSE messaging, and sampled values within a digital substation environment.

IEC 61850 Digital Substations

We verify the integrity of modern digital substations, focusing on station bus, process bus, GOOSE messaging, and Sampled Values. Our team ensures seamless communication and precise signal mapping across complex IED networks.
