Choosing a suitable partial discharge detector requires considering the following factors:
1. Detection range
Firstly, determine the rated voltage range of the electrical equipment that needs to be monitored, and then select a partial discharge detector that can adapt to the range. Generally speaking, the rated voltage range of the detector should be slightly higher than the rated voltage of the monitored equipment to ensure the accuracy and reliability of the detection.
2. Sensitivity
The sensitivity of a partial discharge detector determines the size of the partial discharge signal it can detect, which in turn determines its ability to alert equipment faults. When selecting, it is necessary to select an appropriate sensitivity range based on specific needs and the characteristics of the monitored eq
uipment to ensure effective detection of partial discharge phenomena.
3. Data analysis function
Modern partial discharge detectors are usually equipped with data acquisition and analysis software, which can monitor, record, and analyze partial discharge data in real-time. Therefore, the data analysis function of the detector is also an important factor in the selection. It is necessary to consider the usability of the software, the accuracy of data processing, and the intuitiveness of the results.
4. Portability and ease of operation
A suitable partial discharge detector should have good portability and easy operation, making it easy to use and carry on site. The characteristics of light weight, small size, and user-friendly operation interface are all considered factors.
5. Scalability and Compatibility
Considering the needs of equipment maintenance and upgrades, it is necessary to pay attention to the scalability and compatibility of partial discharge detectors when selecting. Whether external sensors are supported and whether they can be linked with other devices are all issues that need to be considered.
6. Reliability and stability
Due to the fact that partial discharge detectors typically operate in harsh environments for a long time, it is necessary to choose products with reliable quality and good stability. You can refer to user reviews, brand reputation, manufacturer after-sales service, and other aspects to evaluate the reliability of the product.
In summary, selecting a suitable partial discharge detector requires comprehensive consideration of factors such as detection range, sensitivity, data analysis function, portability and ease of operation, scalability and compatibility, as well as reliability and stability, based on actual needs and project requirements.
The ZC-830 handheld partial discharge detector can be widely used for theater detection in power systems, including insulation status detection of high-voltage switchgear, ring network cabinets, voltage/current transformers, transformers (including dry-type transformers), GIS, overhead lines, cables, and other equipment.
The main advantages of the product include:
1. Configure different sensors to realize partial discharge detection of almost all electrical equipment
2. Provide multiple discharge spectra such as time-domain waveform, PRPD, PRPS, etc. to achieve analysis of different discharge types
3. The user-friendly human-machine interface facilitates data management for different devices, achieving 360 ° comprehensive diagnosis of the tested equipment
4. Built in ultrasonic sensors and transient ground voltage sensors, can be externally connected to specialized sensors such as transformers, GIS, overhead lines, cables, etc
5. Adopting non-invasive detection method, there is no need for power outage or additional high-voltage source configuration during the testing process, making it more convenient to use than traditional detectors
6. The testing bandwidth range is 30kHz~2.0GHz, suitable for detection principles in various frequency bands
