    Techimp’s Partial Discharge (PD) Monitoring systems usually consists of a Central Unit and distributed Data Acquisition Units – the PD Hub™ - able to acquire and process the PD signals locally detected through PD sensors installed on each of main electrical assets (generator, transformer, HV cables and GIS).

  • UHF PD Detector

    UHF PDD - Megger Group Ltd.

    Handheld online PD substation surveying system. The UHF PD Detector is the ideal tool for quick, non-invasive surveys in MV and HV substations and should be part of the toolkit for all maintenance and service teams. Due to its high measurement bandwidth, the UHF method provides accurate local online partial discharge (PD) measurements on HV components such as cable end-terminations, surge arrestors, voltage transformers and isolators.

  • PD Measuring System

    TEM - Mess- & Prüfsysteme GmbH

    Partial discharge test system for laboratory or on-site measurement according to VDE 0434, IEC 60270 and EN50178 consisting of:*Partial discharge meter TMG*High-voltage coupling capacitors for decoupling of the PD pulses*Partial discharge calibrator TPK for determining the correction factor in the PD test circuit

  • Portable PD Monitoring

    ASM-P - IPEC Ltd.

    The ASM-P can be configured with up to 32 PD sensor channels. If excessive discharge is detected, the ASM-P raises an alarm that can be configured either locally or by email/SMS. This enables the long-term assessment of plant conditions to be carried out quickly and easily, from any remote computer.

  • Bipolar Magnet PD

    PG501 - W-IE-NE-R, Plein & Baus GmbH

    The WIENER PG501 is a 1.8 kW / 20A class programmable bipolar current source for magnets. The power supply is based on the 3U high 19" PL506/512 chassis design with power bin and a plug-in power supply box which allows replacement of power supplies in shortest time without use of any tools.

  • PD Measurement Devices

    Power Diagnostix Systems GmbH

    The ICMsystem is a digital partial discharge detection system. The instrument is completely controlled by software using a GPIB, USB, TCP/IP, GSM Modem, fiber optic or direct serial link. It can be expanded to up to 10  true-parallel acquisition channels, while offering all features of the single channel  ICMsystem. It is designed for acceptance tests on large power transformers and other application requiring parallel acquisition.

  • PD Monitoring Systems

    Power Diagnostix Systems GmbH

    The ICMmonitor is an instrument for continuous on-line monitoring of partial discharge activity in high voltage equipment. The instrument tracks changes in key discharge quantities for storage in trending diagrams and for triggering user-settable alarms. TCP/IP, Modem, fiber optic or direct serial links enable remote access and full remote control. The latest version of the ICMmonitor comes with spectrum analysis function (formerly know as SPECmonitor), acoustic signal detection, and a conventional partial discharge measurement circuit.
