Frequently Asked Questions
Q
What is the maximum detection distance of this acoustic imaging device?
The device supports a detection distance range of 0.3 m to 150 m, making it well-suited for both close-range inspections and long-distance transmission line surveys.
Q
What types of partial discharge can this device identify?
The device can identify multiple discharge types including suspension discharge, corona discharge, and creeping discharge. It also displays PRPD (Phase-Resolved Partial Discharge) diagrams to assist in accurate diagnosis.
Q
How long does the battery last, and can it be replaced in the field?
The device uses a removable 4900 mAh battery that provides at least 3.5 hours of full-load operation. It comes with 2 spare batteries, allowing users to easily swap batteries and work through an entire day without interruption.
Q
What is the frequency detection range, and why does it matter?
The adjustable frequency range spans from 2 kHz to 100 kHz. This covers the core frequency band associated with partial discharge activity while effectively filtering out background interference signals, ensuring more accurate and reliable detection results.
Q
Does the device support infrared thermal imaging in addition to acoustic imaging?
Yes. The device integrates infrared thermal imaging with a resolution of 640×512 and a temperature measurement range of -20 ℃ to +150 ℃ (and 100 ℃ to 550 ℃ for high-temperature scenarios), alongside acoustic imaging and visible light camera — all in a single handheld unit.
Q
What connectivity and storage options does the device offer?
The device includes 64 GB built-in storage with SD card expansion support. Connectivity options include WiFi, Bluetooth, Type-C (data & charging), TF card slot, SIM card slot (4G/5G), and a 3.5 mm headphone jack for audio monitoring — providing comprehensive data management and communication flexibility.
