Very good service in terms of the fleet management and training, in particular the reporting and training of individual events. We appreciate the preventive alerts on the network when attention to events are needed. Please keep up the good work!

A Focus on Frequency Control

Frequency Control Ancillary Services (FCAS) are critical grid services brought about by AEMO to maintain network frequency within a specified range to ensure system stability and minimise the impact of renewables.

VECTO provides a module for contingency FCAS reporting that lets you fulfil compliance reporting with pinpoint levels of accuracy and with a minimum of effort.

Specialised Power Grid Applications

Power Quality+

IEC61000-4-30-Ed3.0 Class-A compliant Waveform synchronised Power Quality forms the foundation of the VECTO family of devices.


PMU+ works with VECTO’s power quality features, allowing users to record and stream synchrophasor data following the C37.118-2 (IEEE PMU protocol) standards. The PMU+ module achieves both Class-P and Class-M benchmarks simultaneously.

Grid Stability Monitoring

The VECTO devices’ onboard small signal stability algorithm accurately records and alarms sub-synchronous oscillation events.

Contingency FCAS Verification

VECTO offers a dedicated CSV output that can be directly imported into AEMO’s FCAS verification tool (FCASVT), making verification as simple as a few clicks.
