Features
- The PD that takes place within the examination coil is detected by an electromagnetic wave directly
- Partial electric discharge can only be detected by a rising high frequency signal of a narrowband antenna
- High sensitive partial electric discharge examination is possible by placing an antenna near an examination coil
- It is hard to be affected by the examination circuit and can facilitate introduction to product line because the handling is simple
- The automation of the partial discharge test becomes possible.
- The PD detection sensor (micro wave sensor module) can be put up as an option and remodel to the impulse winding examination machine (DWX series).
- The work efficiency improves by a convenient function necessary for evaluating the partial discharge test.Break-down voltage (PDIV), electrical discharge disappearance voltage (PDEV), electrical discharge level (PDpeak), and electric discharge outbreak probability confirmation.
- It is possible to use it visually, plainly and easily as the shape waves of electrical discharge signal can be displayed.
