Online PD Monitoring system for power Transformers

Partial discharge monitoring has become increasingly important in the past few years. Besides other parameters like gas in oil analysis, temperatures, vibrations, or load conditions, etc., the PD trending information completes a full set of monitoring data of a transformer in the field. A series of standard bushing adapter (BA) is available to connect the measurement system to the test tap of condenser bushings. Even special designs are available on request. Additionally, the standard setup using the bushing test tap could be extended with UHF drain valve sensors or embedded antennas in flanges. For continuous monitoring, an instrument such as the ICMmonitor can be considered. Acoustic sensors can be used to locate a PD fault more precisely.

ICMmonitorr with spectrum analyzer

Combining a spectrum analyzer, an acoustic detector, and a conventional partial discharge monitor in one instrument the ICMmonitor enables PD measurements even with a large background noise e. g. on power transformers within substations or power plants.

Spectrum Analysis

Observing the frequency spectrum of a harshly disturbed PD signal allows the selection of frequency bands with fewer disturbances. Using this center frequency for a PD acquisition, gives a largely improved signal-to-noise ratio resulting in a clear pattern acquisition. The combination of spectrum analyzer and PD detector within one instrument greatly expands the measurement possibilities when analyzing the insulation systems in a noisy environment.The ICMmonitor with spectrum analysis comes with a four- or eight-channel multiplexer to directly select the input signal. The instrument provides five different display modes as well as a variety of connectivity options including TCP/IP and USB.
