Currently, monitoring of partial discharge in insulation has become an essential need for reliable and stable operation to optimize production for factories. However, fully equipping the entire solution and mastering technology requires large capital and time, which is considered unfeasible and causes difficulties for some units. Therefore, choosing to use PD partial discharge analysis service of S5T Vietnam Technology and Solution Joint Stock Company is the first choice. Because customers only need to spend very little, but still get detailed data analysis reports for the PD condition happening inside the device.

Benefits of partial discharge analysis in insulation
Online partial discharge monitoring is the collection of partial discharge impulses occurring in the internal and surface voids of the winding insulation. Through analyzing the collected data, it is concluded that partial discharge is taking place and propose solutions to repair and maintain with insulation if necessary. This creates the basis for annual equipment repair and maintenance decisions, in order to improve equipment life, stable production operation and save repair costs.
Benefits of device PD analysis:
- Preventing electrical discharges that damage insulation, leading to serious problems for generators and medium voltage electric motors.
- Helps increase machine reliability.
- Save on repair costs.
- It can be done while the machine is running, so it is possible to collect and find the root cause of the problem, without affecting revenue interruption, and optimizing the factory’s production process.
Application of partial discharge analysis service PD for equipment
The PD analysis service is applicable to the detection of insulation damage in the stator of rotating machines of the following industries:
- Hydroelectric.
- Thermal.
- Wind electricity.
- Other industry.
