FLIR Si2-PD Acoustic Imaging Camera with Partial Discharge

What is the FLIR Si2-PD Partial Discharge Acoustic Imaging Camera?

The FLIR Si2-PD is an advanced acoustic imaging camera designed for UK HV electricians, substation technicians and industrial maintenance engineers who need to detect partial discharge, corona activity and electrical faults before they become dangerous or costly.
Using a high-density 96-microphone ultrasonic array, the Si2-PD converts sound into a visual heatmap, helping engineers identify discharge faults on switchgear, insulators, transformers and overhead equipment, without needing direct contact.

It is ideal for utility companies, high-voltage contractors, industrial plants and predictive maintenance teams responsible for electrical asset reliability.

How does the Si2-PD support HV inspections?

Partial discharge is one of the earliest warning signs of insulation failure.
The Si2-PD uses AI-powered classification to automatically identify the type of discharge (corona, surface discharge or floating discharge) and assess risk severity.
This allows maintenance teams to prioritise repairs, prevent unexpected outages and maintain compliance with HV safety and reliability standards.

Its long-range acoustic detection, intuitive on-screen mapping and easy one-handed operation make it highly effective for scanning substations, switch rooms, cable trays and overhead assets, even in noisy environments.
