Particle Discharge (PD) Tester

The PDSurveyor™ family has been designed to carry out Partial Discharge detection by all operational staff entering the substation or facility. 'Look-see' PD tests can be made quickly and easily to scan large numbers of cables and plant items for PD activity as a prelude to using diagnostic PD test and/or monitoring technology.

With the recent addition of 3x new handheld PD screening units to our standard PDSurveyor™ offering, HVPD can offer solutions for testing all types of MV plant in the voltage range from 3.3 kV to 45 kV, as follows:

  • PDSurveyor™- suitable for cables and switchgear
  • PDS Air™- suitable for indoor and outdoor switchyards
  • PDS Rogowski™- suitable for machines with permanently installed Rogowski Coil sensors
  • Filter

UltraTEV Locator Partial Discharge Locator Kit The UltraTEV Locator Partial Discharge Locator is a partial discharge detection kit from EA Technology which locates, measures and records partial discharge activity (PD activity) in switchgear, transformers and MV Cables. The UltraTEV Partial Discharge Locator instrument combines the features of many PD detection instruments into one portable, easy-to-use kit. UltraTEV Locator Key Benefits  The UltraTEV partial discharge locator kit comprises a central unit with multiple sensors and dual probes, plus a range of accessories. The sensors measure environmental variables which are known to affect PD activity. Allows for Partial Discharge testing on MV cables using the RFCT sensor Test results are easy to interpret from the graphical display Easy-to-use touch screen menu.   UltraTEV Locator Kit Contents: TEV / Ultrasonic Probe TEV / Magnetic Probe Ultrasonic Contact Probe Flexible Sensor Non Contact Temperature Probe RFCT Peltor Neckband Headphones AC Reference Source Battery Charger & Carry Case

UltraMET Plus Ultrasonic Discharge Detector The UltraMET Plus Ultrasonic Discharge Detector Kit is a versatile ultrasonic detection kit from EA Technology. The UltraMET Plus Ultrasonic Discharge Detector provides instant indications of levels of surface partial discharge activity within MV switchgear, cable boxes etc. UltraMET Plus Benefits: Take multiple decibel readings of PD activity. Easy to use menu with backlit screen. Listen for PD activity with headphones.

UltraTEV Partial Discharge Detector The UltraTEV Partial Discharge Detector Kit from EA Technology is a portable partial discharge detector which detects both surface and internal discharge activity within medium voltage equipment. Partial discharge activity causes insulation material to deteriorate and eventually leads to failure of MV equipment. With the UltraTEV Partial Discharge Detector, surface discharge is detected using an ultrasonic sensor and internal discharge is detected using an electromagnetic sensor which can detect transient earth voltages or TEV’s. The kit is used by both technical and non-technical staff. All tests are carried out without the need for an outage. UltraTEV Partial Discharge Detector Benefits Simple to use with minimal training required Lightweight and Rechargeable Improves operator safety Switchgear condition tested without the need for an outage Switchgear can be quickly checked before a switching operation UltraTEV Partial Discharge Detector Kit Contents Carry Case 230Volt Charger Prooving Unit Manufacturers Calibration Certificate

UltraTEV Plus Partial Discharge Detection Kits The UltraTev Plus range of partial discharge detection kits from EA Technology combines the features of the UltraMET Plus, UltraTEV Detector and the MiniTEV into one handheld portable instrument. The UltraTEV Plus detects and measures both surface and internal discharge activity within medium voltage equipment. Partial discharge activity causes insulation material to deteriorate and eventually leads to failure of MV equipment. With the UltraTEV Plus, surface discharge is detected using an ultrasonic sensor and internal discharge is detected using an electromagnetic sensor which can detect transient earth voltages or TEV’s. All tests are carried out without the need for an outage. UltraTEV Plus Benefits: Detects & measures PD activity with graphical display for both ultrasonic and TEV activity. Easy to check if switchgear is free of partial discharge activity Easy to interpret display of test results Easy to use menu driven backlit colour screen and keypad UltraTEV Plus Partial Discharge Detection kit contents UltraTEV Plus Kit 1 Mains chargerFunction checkerClip on...

Product Overview *New* - The PDS Air™ partial discharge surveying tool from HVPD represents the very latest in handheld PD test technology. Incorporating a digital TEV-dB display and external airborne acoustic probes, the test unit provides the 'first-line of defence' for the early detection of PD activity in MV cables and plant from 3.3 kV to 45 kV. Rapid, 'look-see' insulation condition testing is possible through the unique combination of three PD measurement technologies: HFCT, TEV and Airborne Acoustic. The PDS Air™ handheld test unit meets the requirements of both utility and industrial MV plant owners for a simple, portable, and easy-to-use handheld PD screening device for use by all operational staff in the substation. The unit is recommended for use in Phase 1 of the HVPD 4-Phase PD Test and Monitoring Solution which requires PD pre-screening of 100% of the network. Benefits include Digital TEV sensor measurement with numerical LED display. The only handheld PD test unit in the market to combine 3x PD sensor technologies (TEV, Acoustic and HFCT) in one device. Measurement of PD in metal-clad switchgear/plant with airborne acoustic sensors and accurate digital...

PDSurveyor™ Product Overview The PDSurveyor™ is HVPD's original handheld PD surveying tool. It is the 'first-line of defence' for the detection of partial discharge activity in On-line medium voltage (MV) power cables and plant in the voltage range 3.3 kV to 45 kV. The unit enables the user to carry out rapid (10 - 20 seconds per plant item), 'look-see' insulation condition testing through a unique combination of measurement technology, incorporating three types of PD sensor: HFCT, TEV and Airborne Acoustic. The PDSurveyor™ has been designed by HVPD to meet the specific requests from both utility and industrial MV plant owners for a simple, portable and easy-to-use PD test device which can be used by all operational staff in MV substations. The PDSurveyor™ is the most flexible handheld PD screening device on the market as it contains three built-in PD sensors to enable the unit to be used to detect partial discharge activity in MV plant including metal-clad switchgear and power cables. Alternative versions of the unit are now available for specialist purposes, including the testing of rotating machines; see the PDSurveyor™ Family page for more info. The primary...
