Working in a substation, you know that problems rarely announce themselves. One day everything looks fine – the switchgear’s sealed, the cables are solid, the load is steady – and then suddenly, you’re dealing with an unplanned outage.
Falcon 4 provides the system visibility that helps grid operators move from reactive response to predictive control.

That failure didn’t happen overnight. Somewhere inside the insulation, it is likely that partial discharges had been at work – tiny electrical breakdowns eroding the system’s health, one pulse at a time.
A clear window into the network
Doble Engineering’s Falcon 4 was built to give grid operators (asset managers, engineers and technicians) what they need: real-time visibility into the unseen. It continuously monitors medium-voltage assets – switchgears, cables, transformers, and motors – and captures every PD event as it happens.
Falcon 4 classifies signal sources by their pulse signatures. That means it can track the individual phenomena over time and perform an individual identification to distinguish between substation disturbances and partial discharge signals affecting the asset insulation, providing the clarity needed to make decisions based on reality, not assumptions.
In practice, that translates into higher sensitivity to small defects, fewer false positives, and the ability to spot insulation degradation long before it becomes critical.
Built for the field
Site experiences and challenges have shaped the design of Falcon 4: it’s fast to install, non-intrusive, and doesn’t require shutdowns. Clamp on an HFCT sensor or mount the TEVs, and it’s up and running – without taking the system out of service.
No complex calibration, no specialised training. Once connected, the unit configures itself, syncs, and starts streaming PD data to its onboard web interface or the user’s SCADA system. Integration is seamless through IEC 61850, OPC-UA and MODBUS protocols.
It is practical, rugged, and made for the realities of the field.
Smarter maintenance
Condition-based maintenance is today’s standard for high-reliability operations. Falcon 4 makes this attainable by providing continuous diagnostic coverage. Users are informed by an alarm when a PD activity is recognised, behaviour trends can be tracked over time, and data correlated across sites. That means maintenance calls are informed, rather than relying on guesswork. Falcon 4 helps substation engineers move from reactive response to predictive control.
Despite its compact form, Falcon 4 is a leading diagnostic instrument: 4 independent PD channels, 125 MSa/s sampling, 30 MHz bandwidth, and a built-in sync channel for precise phase correlation. It’s engineered for accuracy, reliability, and repeatable results.
When you’re managing critical power assets, confidence in your data is just as important as the data itself.
The Falcon 4 is not just another sensor box. It’s designed to be an engineer’s ally – a constant, intelligent observer that makes the usually invisible behaviour of equipment insulation systems visible, providing insight from the PD alarm to the raw data.
For anyone who’s ever been blindsided by an unexpected fault, this kind of constant vigilance is worth its weight in uptime.
