Astute HV Monitoring
Keep critical high-voltage equipment under constant watch with fixed sensors that flag abnormal activity as it develops.
Real-time alerts to detect issues before they escalate
Flexible monitoring and reporting tailored to your network
Protects critical electrical assets and reduces failure risk
Install fixed sensors on switchgear, cables and other critical equipment without taking assets out of service. Central data collection allows teams to review condition changes across the network without relying on periodic inspections, making it an optimal approach for assets critical to operation, or sites with difficult or impractical access.

Handheld monitoring covers a large proportion of your network, but partial discharge can vary with load and conditions, so occasional checks can miss developing problems on your most critical assets.
Permanent monitoring keeps watch continuously, flagging issues in real time and helping you direct maintenance where it's needed most. It's delivered as a fully managed service, covering installation, data and ongoing support, so you get continuous insight without having to build that capability yourself.
Continuous partial discharge monitoring for proactive asset management and reliable network operation.
Astute HV Monitoring is a permanently installed partial discharge monitoring system for high-voltage switchgear and cabling. It uses fixed sensors to detect and track partial discharge activity, providing continuous insight into the condition of electrical insulation.
It's particularly suited to critical assets: those where failure would be costly or disruptive, where operating conditions make partial discharge activity intermittent or hard to catch in a single measurement, or where regular site visits aren't practical. Used alongside handheld surveys, it extends your coverage and gives continuous protection on the assets that need it most.
The system can be installed on existing infrastructure without requiring an outage. Sensors can be fitted to cable sheath earth connections and on the surface of the switchgear panels, allowing monitoring to continue without interrupting operations.
Data is captured and made available through a central platform, helping network operators, asset managers and maintenance teams investigate potential faults, prioritize maintenance and make evidence-based investment decisions, without needing to build specialist monitoring expertise in-house.
