Off-line Partial Discharge Measurement and Analysis

Partial discharge (PD) activity is a reliable indicator of insulation condition in electrical equipment, as it is often a sign of insulation defects that can potentially cause dielectric failure. That is why PD is an important diagnostic parameter used to assess insulation condition during factory acceptance testing, on-site commissioning and troubleshooting.

You can detect partial discharges already in their early stages with our PD measurement and analysis systems. This allows you to draw conclusions regarding the condition of the insulation. As a result, further measures such as maintenance work and additional diagnostic measurements can be effectively planned.

MPD 800

Our MPD 800 universal partial discharge (PD) measurement and analysis system represents the next generation of our widely-used and innovative MPD PD testing technology. Enhanced and newly-added hardware and software features ensure highly-sensitive multi-channel PD measurements for reliable, industry-standard PD testing on a wide variety of electrical equipment. It accurately detects and localizes insulation defects and helps you to reliably assess the risk of failure and effectively plan maintenance based on insulation condition.

Other solutions

MPD 800 + PDL 650

The combination of the MPD 800 and the PDL 650 enables you to perform partial discharge measurement (PD) and localization on power transformers. If PD activity is detected, the MPD 800 automatically triggers the PDL 650 to perform acoustic PD measurements to effectively locate the source of the PD activity inside the transformer. The location is shown in a 3D image of the transformer to enable you to focus maintenance efforts.

CPC 100 + MPD 800 + 70 kV High-Voltage Upgrade Option

The compact and lightweight High Power 70 kV Upgrade Option is used as an external high-voltage (HV) source with the CPC 100 multi-functional electrical testing system and MPD Series partial discharge (PD) measurement and analysis systems for off-line measurements on HV equipment. It is suitable for voltage withstand tests as well as PD measurements.

MPD 600 + UHF 620

The MPD 600 represents the second generation of our series of advanced partial discharge (PD) measurement and analysis systems. The modular system enables both single- and multi-channel PD measurements in test labs and in the field. It is used together with our UHF 620 for reliable PD testing and diagnosis on Gas-Insulated Switchgear (GIS). The UHF 620 extends the measurable bandwidth of the MPD 600 measurement device up to the VHF and UHF frequency ranges to greatly minimize surrounding disturbances in GIS environments.
