Partial discharge measurement and analysis

Detect insulation defects and prevent failure in your electrical assets.


Reliable condition assessment

Partial discharge (PD) is considered one of the major contributors to the degradation and failure of insulation systems in electrical equipment. 

Compared to other dielectric diagnostic methods, PD measurement and analysis allows you to effectively and reliably assess the insulation condition of a number of high-voltage assets. It is performed during factory acceptance, on-site commissioning and routine maintenance testing to detect insulation defects and assess risks.

Timely corrective action

Since PD activity is often present well in advance of insulation failure, PD measurement and analysis allows you to make informed decisions regarding the timely repair or replacement of equipment to ensure operation reliability.

What is Partial Discharge?

Partial discharge, or PD, causes insulation to progressively deteriorate, which can lead to breakdown and failure in electrical assets. 

Synchronous Multi-Channel Partial Discharge Measurement

Fully digital multi-channel PD measurements are performed synchronously to gather more information about PD activity in less time for advanced analysis.

Partial Discharge Measurement Noise Suppression

Electrical noise can interfere with PD measurements, but it can be eliminated using advanced methods of noise suppression to ensure reliable results.

Partial Discharge Analysis: Fault Detection with 3PARD

The 3PARD diagram helps to separate noise and different PD sources from each other for accurate defect detection.

Partial Discharge Analysis: Sensitivity, Speed & More

Fiber optic connections enhance PD measurement sensitivity and safety. High-speed data transmission allows you to measure PD on many remote channels simultaneously.
