Customer perspectives
One of our strategic pillars is excellent grid management by utilizing existing assets. Implementing Smart Cable Guard was the foundation to enable meshed operations and other innovative operational concepts.

The problem

Almost none of the medium-voltage network is monitored in real time.

It is buried and then left alone. Without continuous monitoring, changes in cable condition and temperature remain difficult to see.

What one medium-voltage circuit actually carries

Continuous monitoring reveals developing faults, changing cable condition and thermal limits — supporting reliability, renewal and capacity decisions.

01

One circuit serves a neighbourhood

A medium-voltage circuit supplies local substations, where transformers connect homes, businesses and essential services to the low-voltage network.

02

Nobody can see inside the cable

It is buried and then left alone for decades. Insulation defects can develop, condition can deteriorate and temperature can change without being visible above ground.

03

Monitoring supports three operational outcomes

Detect developing defects and locate faults to restore service sooner. Prioritise renewal by condition. Use real-time thermal data to assess available capacity.

From monitoring to decision

How monitoring data informs a decision

Live circuit data feeds a model of every circuit as it operates. The resulting insights support fault response, condition-based renewal and capacity decisions.

What it does with that
The chainNetwork → intelligence → decision
Decisionsoutput

Every recommendation traceable to the underlying monitoring data, so the call survives scrutiny.

Solutions

One continuously monitored grid — three operational outcomes

Grid Reliability

Predictive maintenance

Stop managing faults. Start preventing them.

Faults surfaced weeks before they become an outage

Detect insulation defects and cable stress before failure — and locate them precisely when they occur.

Where it applies
  • Prevent faultsDetect weak spots weeks before they become outages.
  • Accelerated fault locationFaster fault location, isolation and service restoration.
What it returns
  • SAIDI / SAIFI reduction
  • Lower cost per callout
Grid Renewal

Lifetime extension

Replace cables based on condition, not age.

Replacement prioritised by cable condition, not age

Redirect CapEx to assets that actually need it — and defend every investment decision with data.

Where it applies
  • Real-time health indexContinuous visibility into actual cable condition.
  • CapEx reallocationDefer spend on healthy cables, invest where it counts.
What it returns
  • Replacement deferred for healthy assets
  • Condition-based investment priorities
Grid Optimization

Capacity increase

Unlock capacity already in your network.

Decisions based on actual operating limits, not static ratings

Real-time thermal data supports capacity decisions based on actual operating conditions rather than static ratings alone.

Where it applies
  • Increase cable capacityReal-time data replaces static worst-case assumptions.
  • Connect more customersOperate closer to thermal margins via RTTR.
What it returns
  • Capacity released without new cable
  • Reduced connection backlog
Where to start

Bring us a network. We will tell you what it is doing.

Start with a pilot on selected circuits, based on your asset risks and capacity priorities. Agree the scope and success criteria before scaling across the network.

Demonstrated impact
25%

fewer power failures across two national distribution networks.

Industries

Power to sell, and no capacity to connect it

The bottleneck moved off the transmission system and onto medium-voltage networks that are rarely monitored continuously.

  • Queues, not shortages

    Power to sell, customers who want it, and no way to carry it.

  • Years, not months

    Long enough to move an investment to another country.

  • Curtailed and waiting

    Output turned down on one side of a constraint while customers wait on the other.

  • The bill arrives anyway

    Congestion costs money whether or not anything gets built.
