PD Systems

Preamplifiers serve to condition, filter, and amplify the partial discharge signal to be measured. Because the frequency range in which PD signals are measured is strongly dependent on the preamplifier used, proper selection of a preamplifier is an important part of noise mitigation and can have a strong effect on the appearance of the partial discharge pattern itself.

HV Filters Partial discharge measurements are conducted in frequency ranges which are partly covered by radio transmission.

The Power Diagnostix line of coupling devices includes quadrupoles, current transformers, and coupling capacitors to adapt Power Diagnostix PD detectors to different measurement tasks. The coupling device in a PD measuring circuit provides the means of sensing the partial discharge pulse and sending it as a voltage signal to a preamplifier for conditioning.

The GISmonitor is a scalable monitoring device for continuous monitoring of gas-insulated switchgear (GIS) using true prarallel, real-time acquisition techniques.

The ICMmonitor is an instrument for continous 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.

ICMcompact PD Detector The ICMcompact is a compact, stand-alone instrument for evaluating the condition of medium and high voltage insulation. It is often used in qualityassurance and quality control tests in manufacturing.

ICMsystem Measurement System. The ICMsystem is a powerful, versatile instrument for evaluating the condition of medium and high voltage insulation.
