PD Detector

The AIAcompact is a portable instrument for in-service acoustic and electric (UHF) partial discharge measurements on high voltage assets such as:

• Gas-insulated switchgears (GIS)
• Gas-insulated lines (GIL)
• Power transformers
• Distribution transformers
• Cable accessories

To be suitable for all these applications, the instrument adapts to a variety of piezoelectric acoustic sensors and pre- processing units. It can be used with acoustic sensors and external ultra high frequency sensors as well as embedded UHF sensors of the tested asset.

Because of its built-in battery and its standalone capability the AIAcompact can even be used for on-site testing in environments where no mains supply is available.

For a convenient remote control of the device, the USB interface allow the connection to a PC or laptop with the optional AIAcompact software installed.

Every AIAcompact comes with a built-in four-channel multiplexer, which allows switching between four input channels. Buttons at the panel of the instrument enable you to directly select one of the four signal sources. As a result, the partial discharge signal and the voltage signal are split and can be selected separately. All settings, e.g., input and display mode, are stored individually for each channel.
