High Voltage Protection Relay Testing & Commissioning — 11kV to 765kV
I'm Dhilipdharan V, a specialist in high-voltage electrical protection relay testing and commissioning with over 7 years of hands-on experience across substations ranging from 11kV to 765kV.
My expertise spans the full protection ecosystem — from numerical relay configuration and IEC 61850 GOOSE communication to primary injection stability testing and disturbance recorder analysis. Cross-brand mastery across ABB, Siemens, GE, SEL, ALSTOM and Schneider Electric, with critical infrastructure delivered across India, Nigeria and Australia.
Deep, cross-platform expertise in protection engineering — from complex relay configuration to full-substation commissioning.
Leading end-to-end testing and commissioning of high-voltage protection systems including primary injection testing, busbar stability, IEC 61850 GOOSE signal verification, and full-substation commissioning across Australia. Key projects include Hunter Power Project (132kV), Broad Sound Solar Farm (275/33kV), Wambo 2 Wind Farm, Swanbank BESS and Wagerup GIS — delivering critical energy infrastructure with zero-defect handovers.
Performed relay configuration, secondary injection testing, and commissioning of protection systems across substations from 11kV to 400kV in India and Nigeria. Managed protection of generators up to 348 MVA and transformers up to 314 MVA. Delivered IEC 61850 SCADA integration for major utilities including PGCIL, KPTCL, HVPNL and RRVPN.
30 major infrastructure projects across India, Nigeria and Australia — from 11kV distribution to 765kV GIS transmission.
