Partial Discharge Detection
PD Detection in Common Scenarios
Dedicated models for partial discharge detection
Handheld, fixed or even drone-mounted options
Identify PD at a Glance
The Acoustic Imaging Camera converts the ultrasound emitted by a partial discharge into an acoustic field localization and superimposes it on the visible light picture captured in real time. With its ability to cover long distances and a wide field of view, the Acoustic Imaging Camera can quickly identify partial discharges
Locate PD in real-time
As the camera scans the area, it instantly visualizes the location of PD on the screen.
Works for all PD types
Inspection teams can quickly and accurately assess the operation of switch cabinet components using acoustic imaging camera, thereby identifying safety hazards in a timely manner.
Safety operation requirements applicable to various scenarios
Acoustic imaging technology, as a non-contact detection means, can ensure the life safety of the staff in the working environment with dense high-voltage facilities. In different power system scenarios, the handheld acoustic imager can accurately analyze partial discharge defects in many different types of key equipment.
Electricity Substations
In substation scenarios, the Acoustic Imaging Camera can efficiently monitor the operation of switchgear, cables, high-voltage chamber porcelain vases, switch insulators, and other equipment while also investigating potential safety hazards.
Distribution system
Distribution lines transport energy to any location that requires electricity, resulting in long and complex distribution lines. The Acoustic Imaging Camera provide ultra-long-distance detection capabilities, allowing inspectors to readily detect numerous equipment on towers from a comfortable distance, ensuring the power system's safe operation.
Listening + PRPD mapping to get more accurate localized discharge type determination
The natural environment has many sound sources in the ultrasonic frequency band, and this situation is especially common in power plants. In order to distinguish the interfering sound sources more effectively, we apply the PRPD map recognition function, which helps us to distinguish the discharge types in the complex environment. Also, our equipment is equipped with an ultrasonic listening function, which can convert audio models in the ultrasonic frequency band into audible sound through a series of processing.
More accurate judgment
The method of listening and mapping can improve the accuracy of the fault identification.
Eliminate the interference of irrelevant sound sources
PRPD mapping can clearly determine the type of sound source.
Minimal Training Requirements
Other PD detection solutions require specialized training to interpret images, distinguish between true PD and false positives, and navigate complex industrial environments. With sophisticated acoustic camera technology, users can quickly learn how to operate the device, saving time and improving work efficiency.

How to Address Partial Discharge in Generators
Partial discharge is a phenomenon that cannot be completely eliminated from high-voltage motors and generators. However, it is crucial to closely monitor and address partial discharge, as it can impact the performance of insulating materials.
In the power industry, inspectors rely on observing the working status and performance of motors by studying the trend of partial discharge intensity in the generator.
If the intensity of partial discharge in the generator shows an upward trend, it indicates a potential issue within the generator. At this point, it becomes necessary to analyze the underlying cause of this phenomenon and conduct a thorough examination of the motor’s functionality.
