Applications
Power Quality Monitoring
Monitor voltage fluctuations, harmonics and other power disturbances to maintain a stable and reliable supply. These solutions are essential across sectors such as utilities, renewable energy and data centres, helping prevent equipment faults, reduce downtime and improve safety.
Fault and Disturbance Monitoring
Quickly detect and analyse faults such as short circuits, overloads and insulation failures. Our solutions help maintain grid stability and minimise disruption by enabling fast fault identification and recovery—critical for sectors including transport, utilities and critical infrastructure.
Phasor Measurement
Support wide-area monitoring with synchronised, real-time measurements of voltage, current and phase angle. These insights help operators maintain grid stability, detect disturbances and take corrective action to protect equipment and ensure reliable performance.
Compliance Monitoring
Ensure safe, efficient and environmentally responsible operation with solutions that support regulatory compliance. From bushfire risk management to renewable energy integration, our systems help operators meet industry standards and reduce operational risk.
