Partial Discharge Testing for Switchgear

Partial discharge (PD) testing provides critical information about the quality of switchgear and its impact on your critical facility. Your medium-voltage switchgear is vulnerable to PD if it has voids, gaps, or other defects. PD can also occur on the surface of insulators. Left unchecked, these small electrical sparks erode insulation and lead to unplanned outages. PD testing for switchgear helps you prioritize maintenance resources and take action before this failure occurs.

Vertiv offers both online and offline PD testing for your solid-insulated and air-insulated switchgear. Depending on your operating requirements and specific application, our experts can monitor your assets periodically or around the clock. We look for a wide range of problems including surface tracking and corona. We also leverage the latest technology to determine the extent and location of insulation degradation in your switchgear. With the results of these tests, you can make better decisions about maintaining, repairing, and replacing your switchgear before it fails. You can better protect your equipment, your people, and your business.

Features

...
Pre-screen and report identifies and prioritizes equipment for PD testing, and documents these recommendations ensuring focus on the right assets
Noninvasive PD sensors are used to conduct periodic PD measurements and increase the reliability of PD detection
Innovative technology enables our test engineers to identify the presence and location of PD within your switchgear
Online PD testing provides a nondestructive, inexpensive testing option that can be performed while your equipment is energized at normal operating voltages
Permanently mounted sensors installed in hard-to-access equipment and areas that pose a safety concern facilitate safer, more efficient PD detection
Short-term continuous monitoring allows switchgear to be continuously monitored under load ranging from one hour up to three months
Permanent continuous online monitoring delivers continuous and accurate information on the condition of the most critical assets in your system
Ultrasonics increase the reliability of PD detection when used with other testing technologies
Offline PD testing can be used to commission new gear or to complete testing when de-energization is preferred

Benefits

...
Improved system reliability occurs when failure-causing PD is remedied
Optimized maintenance and capital expenditures are possible as PD testing helps prioritize equipment requiring maintenance, repair or replacement
Fewer unplanned outages and system downtime results from early identification of PD
Improved risk management happens when PD is regularly monitored and addressed prior to probable failure
