Transformer Partial Discharge Monitoring | PD Monitoring

Partial discharge monitoring identifies insulation defects early in transformers and related high-voltage assets. The page explains electric (IEC 60270), UHF, and acoustic methods, and outlines monitors and sensors—such as E3, DTM, RTD-PD, BAU+, RFCT, Rogowski coils, and coupling capacitors—for accurate detection, trending, and decision-making.

Product Overview

• Detect incipient insulation faults with continuous PD monitoring.
• Compare electric, UHF, and acoustic methods, referencing IEC 60270 and NEMA 107.
• Deploy E3, DTM, RTD-PD, BAU+, coupling capacitors, RFCT, and Rogowski coils.
• Enable directionally sensitive detection and pulse-polarity noise rejection capability.

Monitor transformer health by tracking partial discharge using proven electric measurements, UHF antennas, and online acoustic systems. Measure apparent charge in pC per IEC 60270 and evaluate RIV to NEMA 107. Deploy E3, DTM, RTD-PD, BAU+, RFCT, and coupling capacitors for precise detection, localization, and timely maintenance and asset life.

Target Market

Ideal for utility asset managers, substation engineers, transformer specialists, and reliability teams in transmission and distribution, power generation, renewable plants, data centers, industrials, and mining. Used for online condition-based monitoring, early fault detection, bushing and winding assessment, and planning repairs before unexpected outages.
