PD SURVEYOR Handheld partial discharge (PD) detection without the need for costly outages Quick surveys in live substations The PDS100 is an RFI surveying tool that is designed for use in a live substation. Without the need for outages or special connections, the unit can detect partial discharge (PD) in just a few seconds thus making it an ideal tool for a condition based maintenance (CBM) program. Whole substations can be surveyed and analyzed. The PDS100 is the perfect tool to detect and locate sources of PD. • Safe and effective method for PD detection • Can identify and locate defects using RFI technology • For non-invasive routine surveys of substations • Ideal for every service or test team • Advanced user-friendly diagnostic tool • Perfect tool for a Condition Based Maintenance (CBM) program

High-Frequency Current Transformer A high-frequency current transformer can be clipped on an apparatus ground wire and connected to a PDS100 to confirm internal PD activity. It is possible to scan for electrical pulses (f<200 MHz) as evidence for partial discharge to earth. See and correlate the pulse patterns in time domain (a PDS100 mode). P/N: TN-80308 UHF Transformer probe To confirm findings on the outside of transformers a drain valve probe can be inserted. Connect a Doble UHF TX (DN50/DN80) directly on the antenna input of the PDS100 and insert into the suspect transformer to find radio...

UHF antennae for GIS joints/spacers To do a survey of Gas Insulated Substations (GIS), a Doble UHF antenna can be directly connected to the antenna input of the PDS100 and the sensor can be placed across a joint on a GIS to find evidence of partial discharge inside. See and correlate the pulse patterns in time domain (a PDS100 mode). PN: TN-80315 UHF antennae for substation survey Telescopic: Antenna for wide range capture of UHF signals in open areas. Bandwidth 25-1900 MHz. Length: 310 mm (fully extended). Duck: Fixed-length antenna for wide range captue of UHF signals in indoor areas. Bandwidth...

PDS100 In the tool box for each service team The PDS100 instrument is ideal to use on a daily basis or during routine substation inspections together with other methods like infrared scanning. The PDS100 should be a part of the basic tool box for all service and test teams. The PDS100 is a rugged, light-weight and powerful high-tech instrument with a big display and large soft key buttons. The instrument is easy to use and the software enables the operator to record and analyze the PD signals and make decisions for further actions. The instrument searches for PD in the radio frequency area. Harmful...
