CORE CAPABILITIES
Our Core Testing & Commissioning Capabilities
Spanning every domain of power system verification — from high-voltage
dielectric testing to intelligent electronic device configuration.
T&D Substation Commissioning
Full testing & commissioning of Transmission & Distribution substations from MV up to 380 kV. Covering primary and secondary systems verification, protection coordination and pre-energization checks.
Power Transformer Testing
Comprehensive routine and special tests for power transformers up to 100 MVA. Including insulation resistance, ratio, vector group, excitation current, short circuit impedance, and dielectric tests.
ARAMCO GOSP Substation Testing
Specialized testing & commissioning of ARAMCO Facility Gas-Oil Separation Plant substations. Deep familiarity with ARAMCO engineering standards and SAES compliance requirements.
Advanced Numerical Relay Testing
Testing of Distance, Differential, Overcurrent, Feeder, Motor Protection, and Generator Protection relays. Using state-of-the-art secondary injection test equipment for precise relay characterization.
SCADA RTU Configuration & Testing
Full configuration, testing, and commissioning of SCADA Remote Terminal Units. IED communication over IEC 61850 GOOSE/MMS, DNP3 serial/IP, and Modbus RTU/TCP protocols.
High Voltage Dielectric Testing
AC, DC, and Very Low Frequency (VLF) dielectric testing up to 33 kV systems. Cable insulation, GIS busbar, and switchgear testing to verify dielectric withstand integrity.
Scheme & Functional Testing
Comprehensive functional testing of protection and control schemes including LCC, ACCS, ABTS, ACSE, RTCC, OLTC, ATS, and TLI/TELI protection systems up to 380 kV
Protection System Troubleshooting
Expert diagnostics of existing protection and control systems at both hardware and software levels. Root cause analysis, relay misoperation investigations, and corrective engineering.
End-to-End Protection Testing
Full primary injection end-to-end testing of protection systems including coordination verification, logic testing, and relay setting validation across the complete protection chain.
