Partial discharge coupler CD-24
Partial Discharge Sensor for rotating machines and other applications
- PD decoupling unit with coupling capacitor and integrated measuring impedance for decoupling of PD signals from standard measuring circuits according to IEC 60270
- Coupling capacitance 2 nF for high sensitivity
- Signal transmission bandwidth above 20 MHz at 50 Ω matching resistance
- Especially developed for permanent installations
- For continuous on-line monitoring or periodical measurements of PD at generators and motors
- Composite signal output (superimposed PD and voltage), only one cable needed for installation
- Voltage signal for synchronization allows generation of phase-resolved PD patterns
- High voltage fuse integrated, decoupling unit will become high-impedance in case of failure (CD-24)
