The FLIR Si2-PD partial discharge acoustic imaging camera is designed to detect and assess electrical partial discharge in high-voltage systems for faster, safer inspections.
The FLIR Si2-PD partial discharge acoustic imaging camera helps you reduce maintenance costs for electrical equipment by offering an effective solution for partial discharge (PD) detection and response. This camera detects, locates, classifies, and assesses PD faults from up to 200 m (656 ft) away, identifying PD issues 30 times smaller than previously possible. It provides on-camera and software-based severity assessments, giving you the decision support needed for precise maintenance decisions.
Dedicated Partial Discharge Detection
Designed specifically to locate PD sources in high-voltage electrical systems from a safe distance.
Severity Assessment & Classification
Helps prioritize corrective action by assessing PD intensity and supporting more confident decision-making.
Fast, One-Hand Operation
Lightweight, handheld design supports rapid inspection routes with minimal training.
Clear Acoustic Visualization
High-performance microphone array and real-time acoustic imaging make PD locations easier to identify in the field.
High-Voltage Substation Inspections
Identify partial discharge activity in energized equipment without shutdowns.
Electrical Asset Reliability Programs
Improve maintenance planning by detecting insulation defects early.
Switchgear & Transformer Monitoring
Pinpoint PD-related issues in critical components before failure.
Utility & Industrial Electrical Maintenance
Reduce downtime risk while improving inspection safety and efficiency.
