Oscilloscopes drive partial discharge measurement system

The MS Pico system uses patented “BlueBOX” partial discharge measurement and analysis technology to assess the condition of the insulation of appliances, equipment and materials for high-voltage installations such as GIS, transformers and, especially, insulated cables, either during operation in the network (on-line) or out of service by mobile generators (off-line).

BlueBOX Technology digitally processes captured signals in order to distinguish transient events that are a characteristic of partial discharge signals from the normal patterns of the electrical noise.

With this technology it is possible to find partial discharge signals obscured by the noise level, even when the noise is random.

Javier Ortego, Managing Director at DIAEL, said “The PicoScope 5000D enables capture of high-speed transients with sampling speeds to 1GS/s at 8-bit resolution, and can be switched to measure slower signals with up to 16-bit resolution and greater than 70dB SFDR, making it ideal for the wide range of signals that need to be captured with the MS Pico test system.”

Trevor Smith, Business Development Manager at Pico Technology, added his support, saying “DIAEL has a proven track record in partial discharge testing, having been granted US patents for a new method to monitor partial discharge in high-voltage cables with splices and terminations. The PicoScope 5000D has helped DIAEL to bring that technology to market in an affordable form factor for power network operators.”

The MS Pico test system is available now, sold through the network of DIAEL distributors worldwide.
