Light-speedpower system protection & monitoring
The world's only passive electrical sensor networks for high voltage power systems. Actionable information that improves reliability and reduces operational cost.
The power system instrumentation experts
Since 2014, we've brought together specialists in power systems, photonics, electronics and data analysis to build robust, creative engineering that answers our customers' real needs.
From first workshop to final commissioning, we make grid visibility simple. We believe monitoring every cable, joint and remote asset isn't a nice-to-have anymore – it's how the energy transition stays on.
The right protection for every network

Power grids
Mixed circuit protection
The world's fastest multi-zone protection for circuits combining overhead line and cable, informing safe auto-reclose in milliseconds.
Power grids
Greenlight® for power grids
Early warning of damage and failure in cable networks, cutting costly, high-risk manual inspection and unnecessary outages.
Offshore wind
Greenlight® for offshore wind
Monitor every export and array cable joint and termination, the places conventional techniques can't see.
Offshore wind
Distributed power quality monitoring
Synchronised, high-fidelity power quality data from across the wind farm, with no power or comms needed at each turbine.
Power grids
Synchronised waveform monitoring
Waveforms synchronised to within one microsecond from many locations, across up to 60 km of fibre.
Distributed Electrical Sensing uses the optical fibre already in power networks to measure voltage and current at many locations. No control power, no data networks, no civil works at the point of measurement. Just synchronised data, at the speed of light.
Sensing distance from a single substation over standard optical fibre.
Measurements synchronised to within one microsecond across every sensor.
Processing time, powering the world's fastest multi-zone protection.
Power needed at the sensor. Fully passive, zero maintenance, cyber secure.
See cable failures coming. Keep the power, and the revenue, flowing.
Greenlight® gives grid and offshore wind operators early warning of damage in every cable joint and termination, so you can intervene before an outage, not after.

Why choose Distributed Electrical Sensing?
Robust, scalable, zero-maintenance and retrofittable. A radically better way to protect and monitor the networks the energy transition depends on.
Quick to install
Commissioned from a single location in days rather than weeks, with no complex wiring or telecoms.
Synchronised measurements
Synchronised to within one microsecond and processed in under 200 microseconds.
Long-distance monitoring
Compare remote measurements across hard-to-reach locations, up to 60 km from the substation.
Resilient technology
Ultra-stable year-round, adjusting automatically to the most challenging environments.
Cyber secure
Hardened sensor networks transmit no data. Insights are only produced inside the substation.
Passive sensors
Fully passive sensing of voltage and current. No control power, no maintenance, no recalibration.
Trusted by operators on the world's most demanding networks
