Baur PD-SGS handheld PD detector

The Baur PD-SGS handheld PD detector is used to conduct rapid initial tests for partial discharge (PD) activities on live switchgear.

The survey instrument is suitable for determining the state of health of electrical assets such as HV and MV switchgear, and potential weak points are immediately signalled acoustically and numerically. The user is provided with recommendations for how to deal with the switchgear under test by a traffic light system, making it possible to evaluate the condition of the entire substation to action maintenance work or to conduct further investigations. The product can also conduct checks to determine whether the work area around the switchgear is safe.

The capacitance coupled TEV detector measures surface voltage in the frequency range of 20 to 200 MHz. Ultrasound measurement for internal PD has a range of -6 to 70 dBµV and results are displayed on an OLED with dB indicator. It also has an automatic detection of background interference signals.

The product has a connector for a parabolic aerial for examining difficult-to-reach system components. The instrument is also supplied with a Li-ion rechargeable battery (12 h functional time) and chargers for use in vehicles and with mains power.

The plastic housing with a protective rubber sleeve around the sensors has an IP54 rating, making it suitable for outdoor use. The product package includes stereo headphones, chargers and a transport case.
