(OPDS) arc PD diagnostic system

OPDS arc PD measurement sensing unit through the signal cable and field high-speed partial discharge signal acquisition unit are connected directly. Arc PD measurement sensing unit of the board put the optical signal generated by conditioning amplifier is sent to the signal acquisition unit, a signal acquisition unitconverts the signal into digital signal through the optical fiber will further the signal to background processing unit. Background processing unit is installed withanalysis software of PD, the received signal will result in graphical form displayed.Using fiber as the signal transmission medium, so the long-distance signal transmission is very convenient, good electrical isolation measures to ensure that the system has strong anti interference level. The system has good scalability, canaccording to the monitoring module needs to extend an arbitrary number of.

Monitoring system consists of three main parts:

A OTE signal acquisition device;

A monitoring host computer or laptop (for mobile devices);

Some for power supply and data transmission cable.

The OPDS system has the following advantages:

1, strong anti-interference ability

For many common interference sources are strong antijamming ability, such as:Radio / TV interference, ultra high frequency interference, mobile communicationinterference, plane interference, vibration interference.

2, put the accurate positioning of power supply capacity

Through the rational allocation of the arc sensor can accurately determine eachchamber occurring arc.

3, flexible configuration, strong scalability

For each pressure cavity separately experimentation area and GIS design.
