For grid operators — TSOs & DSOs

Continuous thermal intelligence for your substations.

Catch developing faults between inspection rounds — with deterministic, auditable alerts your engineers and regulators can trust.

The challenge

Periodic inspection leaves a blind spot.

Substation assets change thermally long before they fail — but manual thermography is periodic. A fault that develops between rounds stays invisible until it trips, and current always-on monitoring solutions bury operators in weather- and load-driven false alarms.

The solution

Always-on health tracking for every substation asset.

ZeroParallax’s edge thermal sensors feed the ZeroFlow platform — continuous, deterministic, auditable monitoring of all substation assets ranging from transformers to hard-to-monitor connectors.

24/7 Continuous

Edge thermal sensing replaces periodic manual rounds — always on, 365 days.

Comparative detection

Identical assets are compared to each other; a developing fault shows weeks early.

Auditable, not black-box

Every alert is deterministic — it can be explained and repeated.

Explainable alerts

Every alert comes with a package: the asset, severity, a probable cause and suggested steps — ready to act on.

ZeroTools — live asset health
ZeroTools dashboard

Meaningful alerts, not noise.

Weather correction

Cloud, sun, precipitation and ambient effects are filtered out automatically.

Load-adjusted baselines

Expected temperature tracks real load — so normal operation never alarms.

Perimeter security included

Thermal intrusion detection in the same platform — no separate CCTV.

Built to be trusted

Field-tested and recognised.
