SOLUTION

Switchgear & Grid Equipment Intelligence

Improve visibility into partial discharge, thermal behavior, insulation condition, breaker-mechanism health, and connection-related conditions.

WHAT CAN GO WRONG

Make Intermittent Degradation Visible.

Partial discharge, breaker wear, and connection degradation are often intermittent — a single snapshot can miss them. Monitoring should catch developing signatures and trends, not just a point-in-time reading.

  • Insulation degradation
  • Partial-discharge activity
  • Hot joints and connection problems
  • Humidity, condensation, or contamination effects
  • Breaker or contact deterioration

SIGNALS THAT MATTER

Use measurements that relate to the problem.

No single signal provides complete visibility. The useful combination depends on the failure mechanism, environment, and information already available.

Partial DischargeUHF, TEV, ultrasound and related indicators
TemperatureBusbar, termination, breaker and contact behavior
HumidityEnvironmental context for insulation risk
Current / LoadOperating context for interpretation
UltrasoundAcoustic indicators of abnormal electrical activity
EnvironmentCondensation, salt, dust and temperature cycling
Passive SensingBattery-free / wireless options where practical
Trend HistoryChange over time rather than one-time detection

MECHANISM INTELLIGENCE

Circuit Breaker Mechanism Intelligence

Where available, breaker-operating signals add a mechanical dimension to electrical and thermal monitoring. Signals are technology-agnostic and not assumed to exist on every installation.

Trip/Close Coil CurrentOperating-coil signature and timing
Operating TimeMechanism speed and consistency across operations
Contact TravelMechanical travel where instrumented
Charging Motor CurrentSpring-charging mechanism behavior
Operation CountCumulative duty and maintenance context
Contact ResistanceContact wear and connection quality
SF6 Pressure / DensityWhere applicable to gas-insulated equipment
Thermal BehaviorBreaker-specific thermal indicators

EVEX APPROACH

Asset-first and technology-agnostic.

Start with existing operational information and the diagnostic objective. Add sensing only where it creates meaningful visibility, then use engineering analytics, trend analysis, asset-specific baselines, anomaly detection, and sensor fusion where appropriate.

TYPICAL ENGAGEMENT

Start focused. Prove value.

A practical engagement can begin with an asset-health and monitoring assessment, followed by a focused pilot using existing data and selected additional sensing.
