Partial Discharge Surveyor

Check in-service substation equipment for signs of internal insulation damage

The Doble PDS100 Partial Discharge Surveyor is a radio frequency interference (RFI) surveying tool that is designed for partial discharge measurement in a live substation.

Product Description

Check in-service substation equipment for signs of internal insulation damage

The Doble PDS100 Partial Discharge Surveyor is a radio frequency interference (RFI) surveying tool that is designed for partial discharge measurement in a live substation.

Without the need for outages, the PDS100 can detect partial discharge (PD) in just a few seconds – making it an ideal tool for a condition based maintenance program.

Whole substations can be quickly surveyed and analyzed by simply walking around HV apparatus and using the PDS100 to detect and identify sources of PD and external interference.

Features

Uses RFI technology to identify and locate defects
Detect harmful PD by the electromagnetic energy emitted from the area of activity
Compare reference baseline to readings from inside the substation
Synchronize signal capture to the power cycle to facilitate phase resolved PD analysis
Spectrum and time modes
Store recordings in the instrument and later transfer to a PC for further analysis with PDViewer software
Rugged, light-weight, hand-held instrument
Works with a variety of sensors, probes and antennae for various applications

Benefits

Safe and effective method for PD detection
Non-invasive inspection method for substation surveys
Use on a daily basis or during routine substation inspections together with other methods such as infrared scanning
Cost-effective way to include PD detection in your condition based maintenance program

	Duck Antenna Fixed-length antenna for wide range capture of UHF signals in indoor areas Bandwidth <1000 MHz Length: 210 mm
	DA100 Directional Antenna Evaluate the potential direction of PD and RFI sources Can be handheld or mounted on tripod Bandwidth 250MHz – 1GHz Diameter: 290 mm
	Telescopic Antenna Antenna for wide range capture of UHF signals in open areas Bandwidth 25-1900 MHz Length: 310 mm (fully extended) Standard accessory for PDS100
	Whip Antenna Fixed-length antenna for wide range capture of UHF signals in open areas Bandwidth 25-1900 MHz Length: 410 mm Standard accessory for PDS100
	UHF spacer sensor Connect a Doble UHF antenna directly to the antenna input of the PDS100 Place the sensor across a joint on a GIS to find evidence of partial discharge inside See and correlate the pulse patterns in time domain mode
	TEV probe Find PD in metal-clad switchgear and internally in transformers Connect the TEV probe directly on the antenna input of the PDS100 Move the sensor across a grounded metal surface to find the location of the strongest signal amplitude
	HFCT Clip on an apparatus ground wire and connect to the PDS100 to confirm internal PD activity Scan for electrical pulses (f < 200 MHz) as evidence for partial discharge to earth See and correlate the pulse patterns in time domain mode
	UHF Drain Valve Sensor DN50/DN80 Use on HV transformers for decoupling of electromagnetic PD signals from inside of transformers Sensor fits into DN 50 or DN 80 drain valves Supports “Performance/ Sensitivity Check” where high frequency test pulses can be injected with further integrated electrodes Grounded sensors (for low frequencies)
