Frequently Asked Questions
Q
What is the maximum detection distance of this acoustic imager?
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 is capable of identifying multiple discharge types, including suspension discharge, corona discharge, and creeping discharge. It also displays PRPD (Phase Resolved Partial Discharge) diagrams for detailed analysis.
Q
How long does the battery last, and can it be replaced in the field?
Each removable battery provides a minimum of 3.5 hours of full-load operation. The device ships with 2 spare batteries, allowing continuous use throughout a full working day without needing a power outlet.
Q
What is the detectable frequency range, and why does it matter?
The adjustable frequency range spans 2 kHz to 100 kHz, which covers the core frequency band associated with partial discharge activity. This range also effectively shields out environmental interference signals, improving detection accuracy.
Q
Does the device support infrared thermal imaging in addition to acoustic imaging?
Yes. The device integrates infrared thermal imaging (640×512 resolution, temperature range -20 ℃ to 550 ℃) alongside acoustic imaging, enabling simultaneous thermal and acoustic analysis on the same 5-inch split-screen display.
Q
What connectivity and storage options are available?
The device features 64 GB built-in storage with SD card expansion support, Wi-Fi and Bluetooth wireless connectivity, a 4G/5G SIM card slot, a Type-C port for charging and data transfer, a TF card slot, and a 3.5 mm headphone jack for real-time audio monitoring.
