The Silent Killer in Your Substation
Imagine a tiny, invisible spark inside your switchgear. It’s not causing an outage—yet. But every time it flickers, it’s silently eating away at the insulation, like termites in your walls. This is partial discharge (PD), a common but dangerous precursor to major electrical failures.
For decades, finding PD meant relying on indirect methods: listening with a stethoscope-like ultrasonic probe (tedious and subjective), or analyzing complex electrical signals (requires deep expertise). You knew something was wrong, but pinpointing exactly where? That was the real challenge.
What if you could just... see it?
That’s where acoustic imaging changes everything.
How It Works: Turning Sound into Sight
When partial discharge happens, it doesn’t just create an electrical anomaly—it also generates a unique burst of ultrasound. Our HertzInno handheld acoustic camera is designed to catch this sound and make it visible.
-
Listen with an Array: The device uses a grid of dozens of sensitive microphones to capture these faint ultrasonic signals from all directions.
-
Triangulate the Source: Sophisticated beamforming algorithms instantly calculate the precise location of the sound source.
-
Overlay on Reality: The magic happens on the screen. The camera overlays a bright, color-coded sound map directly onto the live video feed of your switchgear. Suddenly, that invisible spark becomes a glowing hotspot on your screen.
Why This Matters for Your Team
-
No Guesswork: Your technician points the camera, and the problem lights up. No more hours of probing or interpreting cryptic waveforms.
-
Safety First: Inspections are done from a safe distance, without opening panels or getting close to live components.
-
Speed & Efficiency: A full switchgear bay can be scanned in minutes, not hours. Find the fault, fix it, and get back to work.
-
Confidence in Every Scan: Whether it’s a seasoned veteran or a new hire, the visual result is clear and unambiguous.
From Reactive to Truly Predictive
With this technology, you’re not just fixing problems—you’re preventing them. Catching PD early means avoiding catastrophic failures, unplanned downtime, and costly repairs. It’s about turning your maintenance strategy from a cost center into a reliability engine.
