General Information
This system is mainly suitable for partial discharge detection of micro and small electrical components and insulation materials such as transformers, cables, low-voltage switchgear, etc. It can apply high voltage of 5kV to power equipment to inspect whether there are defects (partial discharge) in the insulation materials of power equipment, to assess the partial discharge level of the product, and to discover insulation defects of the tested object.
Features
1. Integrated structural design, convenient to use
The overall structure adopts an integrated structure, with intelligent boosting operation and synchronous collection of partial discharge signals.
2. Strong anti-interference ability and reliable result data
It adopts a closed object structure to shield certain interference sources. It also has software anti-interference design and multiple anti-interference methods to adapt to harsh electromagnetic environments.
3. Simple and convenient connection
Using software connections to automatically shrink and facilitate the connection of the sample.
4. Multi signal acquisition
The independent interface displays high-voltage voltage, high-voltage current, low-voltage voltage, low-voltage current, time and withstand voltage results, and the high-voltage curve is dynamically displayed, making the display intuitive and clear.
5. Comprehensive protection functions
Complete overvoltage, overcurrent protection, flashover protection, self-setting output voltage, high-voltage current upper limit, and timing time.
6. Diversified operating methods
The human-machine interface adopts PC platform operation mode, with intelligent working process and optional automatic and manual modes.
7. Powerful software functionality
Save experimental data manually or at any time, store waveforms at any time, re-display and analyze test waveforms that have been saved in the past, the gain range has six levels of coarse adjustment, and each level can be fine-tuned at will. Digital windowing technology can avoid the impact of interference on measurements.
8. Comply with national and international standards
The partial discharge display results of this software comply with the IEC60270 standard.
