High Voltage Services for Safe and Reliable Field Delivery
ICS Group provides high voltage services across substations, renewable energy systems, industrial facilities and electrical infrastructure projects throughout Australia. Our team supports HV work scopes from planning through to testing, commissioning, fault investigation, energisation and final documentation.
Our High Voltage Capabilities Include:
- High voltage work planning and execution (HV access, permits, risk assessments, isolation and switching programs)
- HV switching, isolation and re-energisation (planned outages, shutdowns and emergency response)
- Primary HV equipment testing and verification (switchgear, circuit breakers, RMUs, disconnectors and earthing switches)
- Transformer testing and assessment (power and distribution transformers, OLTCs and auxiliaries)
- Testing of reactive plant (shunt reactors, capacitor banks and harmonic filters)
- HV cable testing, diagnostics and fault location (IR, VLF, AC withstand, tan delta, sheath testing and PD)
- HV cable termination, jointing and interface testing
- Protection relay configuration, testing and validation (settings, logic, interlocking, tripping and scheme verification)
- IEC 61850 systems and GOOSE configuration and testing
- SCADA and communications testing (telemetry, alarms, indications, controls and remote interfaces)
- Testing and integration of renewable and storage assets (solar inverters, wind farm kiosks, BESS and grid interfaces)
- HV switchgear and feeder functional testing (interlocks, permissives and fail-safe operation)
- Earthing system testing and verification (earth continuity, step and touch, resistance and bonding integrity)
- HV fault investigation
- Documentation and deliverables (switching sheets, test records, as-left settings and reports)
