DWX-05PD impulse coil partial discharge tester. Commonly used inverter coils, insulation reliability requirements include partial discharges, such as household appliances and automotive products. DWX-05PD is used for industrial products, motors, transformers, etc
Testing the windings of motors and transformers can also be viewed as testing insulation at peak voltage.
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 remodeled to the impulse winding examination machine (DWX series).
The work efficiency improved 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 probability outbreak confirmation.
It is possible to use it visually, plainly and easily as the shape waves of electrical discharge signal can be displayed.
With regards to motor
