A single faulty switchgear connection at one of the world's busiest airports caused an 11-hour blackout, cancelled 1,200 flights, stranded 30,000 passengers, and cost one airline an estimated $50 million. The fire that triggered it likely showed thermal warning signs for weeks. OXmaint's continuous electrical thermal monitoring detects overheating in switchgear, panels, and power distribution systems before temperatures reach critical levels — turning invisible thermal risks into actionable maintenance alerts.

The Electrical Fire Problem Airports Cannot Afford to Ignore
Airports run on electricity. Every system — from air traffic control and runway lighting to baggage handling and security screening — depends on continuous, reliable power. Yet the electrical infrastructure powering these systems is aging, increasingly loaded, and monitored only through periodic inspections that miss fast-developing faults. The consequences range from costly outages to catastrophic fires.

What OXmaint Monitors — Every Connection, Every Second
OXmaint integrates with wireless thermal sensors permanently installed on busbars, cable terminations, circuit breakers, and other high-risk connection points inside your electrical infrastructure. Temperature data flows continuously to a centralized dashboard, with AI analyzing trends and triggering alerts the moment readings deviate from baseline.

Every temperature reading tells a story. OXmaint correlates thermal data with load patterns, ambient conditions, and maintenance history to predict failures — not just detect them.

From Temperature Spike to Preventive Work Order — Automatically
OXmaint does not just collect temperature data — it acts on it. When a thermal sensor detects an abnormal rise, the system diagnoses the probable cause, assesses fire risk, and generates a fully loaded work order with parts, procedures, and priority before your team even sees the alert.
1
Continuous Thermal Monitoring
Wireless sensors on busbars, breakers, and terminations report temperature every 15 seconds to the OXmaint platform
2
AI Trend Analysis
Machine learning compares readings against baselines, load profiles, and ambient temperature to distinguish real anomalies from normal fluctuations
3
Risk Classification
System assigns a thermal severity score (1–100) based on rate of rise, absolute temperature, component criticality, and historical failure data
4
Auto-Generated Work Order + Dispatch
Preventive work order created with component ID, thermal data, repair procedure, required tools, and assigned to the nearest qualified electrician
Thermal Severity Scale — What the Readings Mean
Not every temperature rise is an emergency. OXmaint classifies thermal conditions into five severity levels based on NFPA 70B guidelines and industry best practices, so your team knows exactly when to monitor, when to schedule, and when to act immediately.
NORMAL
0–10°C above baseline
No action required — continue monitoring
ATTENTION
11–20°C above baseline
Investigate at next scheduled maintenance window
SERIOUS
41–70°C above baseline
Repair at earliest opportunity — increase monitoring frequency
CRITICAL
70°C+ above baseline
Immediate action — de-energize and repair now
Annual Inspections vs. Continuous Monitoring — The Gap That Starts Fires
Most airports rely on annual or biannual infrared thermography inspections — a trained technician with a thermal camera scanning accessible panels on a fixed schedule. While valuable, this approach has fundamental blind spots that continuous sensor monitoring eliminates.

What Airport Electrical Teams Are Reporting
Electrical systems managers, facility maintenance directors, and infrastructure reliability engineers at airports of all sizes are moving from scheduled IR inspections to continuous thermal monitoring. Here is what they are seeing after deployment.
GH
Greg Harmon
Director of Electrical Infrastructure, Large U.S. Hub Airport
Three months after installing thermal sensors on our main switchgear, we caught a busbar connection degrading at a rate that would have caused an arc fault within six weeks. Our annual IR inspection was not scheduled for another nine months. That single catch avoided what we estimate would have been a $2M repair bill and a 14-hour terminal outage. The system has now flagged 23 developing issues in its first year — all resolved during planned maintenance windows.

Sandra Liu
Facility Maintenance Director, International Airport Authority
We manage 340 electrical panels across three terminals. Before continuous monitoring, our IR inspections covered maybe 60% of them each cycle because of access restrictions and scheduling. Now every panel is monitored permanently. Our insurance provider actually reduced our premium after seeing the real-time monitoring data during their risk assessment.
RB
Robert Bakken
Infrastructure Reliability Engineer, Nordic Airport Group
The thermal trending capability changed how we plan maintenance. Instead of fixed-schedule breaker replacements, we now replace based on actual thermal degradation data. Our maintenance spend on electrical components dropped 28% in the first year while our uptime actually improved. The AI catches load-dependent faults that only appear during peak traffic — something a scheduled inspection at 6 AM would never see.
Frequently Asked Questions
Does continuous thermal monitoring replace infrared thermography inspections?
It complements them. Continuous sensors cover all monitored connection points 24/7, catching fast-developing and load-dependent faults that periodic inspections miss. However, IR thermography still adds value for visual confirmation and inspecting areas without permanent sensors. OXmaint integrates data from both approaches into a single dashboard.
What types of thermal sensors does OXmaint support?
OXmaint integrates with wireless thermal sensors from major manufacturers that mount directly on busbars, cable terminations, breaker contacts, and other high-risk points. These sensors communicate via Modbus, wireless protocols, or direct cloud upload. The platform also accepts data from environmental temperature sensors and gas-detection heat monitors.
Book a demo to discuss your specific sensor requirements.
How does the system distinguish real thermal anomalies from normal temperature changes?
OXmaint's AI engine establishes thermal baselines for each monitored point and correlates temperature readings with current load, ambient temperature, time of day, and historical patterns. This eliminates false alarms from seasonal changes or normal load variations — only genuine deviations trigger alerts and work orders.
Is this NFPA 70B compliant?
Yes. Continuous thermal monitoring aligns with NFPA 70B recommendations for conditions-based electrical maintenance. OXmaint provides the documentation, trending data, and audit trails needed to demonstrate compliance to insurers and regulators.
