PD Measurement

Offline Partial Discharge (PD) Measurement

Ensure Electrical Asset Reliability with Offline PD Testing

At Asset Condition Monitoring, we provide specialized Offline Partial Discharge (PD) Measurement Services to assess the insulation health of your medium- and high-voltage equipment. Using IPEC’s industry-leading PD testing technology, our engineers deliver accurate diagnostics that help prevent failures, minimize risks, and extend the life of critical assets.

What is Offline PD Testing?

Offline PD testing is a controlled diagnostic method where electrical equipment is temporarily taken out of service (planned shutdown) and tested under applied voltage stress. This approach eliminates background noise and interference, allowing for highly sensitive detection of partial discharge activity within insulation systems.

Steps in Offline PD Measurement

At assetconditionmonitoring.com, we follow a structured process to ensure accurate and reliable offline PD measurements.

01

Site Planning & Shutdown

  • Our engineers coordinate with your team to plan the required equipment shutdown.
  • A safe test setup is established, ensuring minimal disruption to operations.

02

PD Measurement

  • Using advanced IPEC offline PD testing equipment, we apply voltage to the de-energized asset.
  • Partial discharge activity is measured across the insulation system, pinpointing weaknesses or defects.

03

Preliminary Results

  • Immediate insights are shared onsite, enabling quick decision-making and faster return to service.

04

Detailed Reporting

  • A comprehensive PD test report is issued, highlighting test results, asset condition, and recommended corrective actions.

Frequently Asked Questions

What is offline PD testing?

+

Offline Partial Discharge (PD) testing is performed when electrical equipment is de-energized and connected to a controlled power source. It helps detect insulation defects and weak points before the equipment is put back into service.

How is partial discharge measured?

+

Partial discharge is measured using specialized sensors and detectors that capture electrical pulses or acoustic signals generated by insulation defects. The readings are quantified in picoCoulombs (pC) to indicate discharge magnitude.

What does the PD test result indicate?

+

The PD test result reveals the presence, severity, and location of insulation weaknesses. High or localized PD activity often indicates potential faults that could lead to equipment failure if not addressed.

What is the acceptable value for partial discharge?

+

Acceptable PD values vary depending on equipment type and standards, but generally, values below 10 pC to 100 pC are considered safe. Higher levels may require closer monitoring or corrective maintenance.
