Global Partial Discharge Monitoring Systems Market Size, Share, Analysis Report By Type (Temporary Monitoring System, Permanent Monitoring System), Application (Power Cables, Transformers, GIS, Others), Region and Key Players - Industry Segment Overview, Market Dynamics, Competitive Strategies, Trends and Forecast 2025-2034
Report Overview
The Partial Discharge Monitoring Systems Market size is expected to be worth around USD 880.6 million by 2034, from USD 535.5 million in 2024, growing at a CAGR of 5.1% during the forecast period from 2024 to 2034.
Partial discharge monitoring systems are essential tools used in high-voltage electrical equipment to detect and assess partial discharges—small, localized electrical sparks that occur within insulation due to defects or stress. While these discharges do not immediately cause equipment failure, they can gradually deteriorate the insulation, potentially leading to significant breakdowns if left unmonitored. These systems utilize various sensors, such as ultrasonic or electromagnetic types, to continuously monitor and collect data on PD activity. The information gathered helps maintenance teams evaluate the severity and location of the issue, enabling timely intervention. Widely used in power plants, substations, and industrial settings, these systems play a crucial role in improving equipment reliability, preventing unexpected failures, and reducing operational downtime by facilitating predictive maintenance strategies.
The growth dynamics of the partial discharge (PD) monitoring systems market are driven by the increasing demand for reliable and uninterrupted power supply across industries. As power infrastructures age and the global energy sector expands—especially with rising renewable energy integration—there is a heightened need to monitor the condition of high-voltage equipment like transformers, switchgear, and cables. Partial discharge monitoring systems are gaining traction because they help detect insulation faults early, thereby preventing costly failures and unplanned outages.
North America’s leadership in the partial discharge (PD) monitoring systems market is largely attributed to its well-established power infrastructure, advanced industrial base, and ongoing emphasis on energy efficiency and system reliability. Industries such as power generation, utilities, aerospace, and manufacturing are actively incorporating PD monitoring to reduce downtime and enhance equipment performance. The aging grid infrastructure in the U.S. and Canada necessitates continuous condition monitoring to avoid unexpected failures, while strict regulations further push the need for such systems.
The COVID-19 pandemic had a mixed impact on the partial discharge monitoring systems (PDMS) market. On one hand, the demand for PDMS systems saw some disruptions due to delayed project timelines, reduced industrial activity, and supply chain challenges during the lockdowns. Many industries faced temporary shutdowns, which delayed the installation and maintenance of power infrastructure. On the other hand, the pandemic also highlighted the importance of reliable and continuous monitoring of critical infrastructure, driving the adoption of PDMS for remote monitoring and predictive maintenance. With the increasing shift toward automation and the need for minimal on-site interventions, the pandemic accelerated the demand for digital and remote monitoring solutions, including PDMS, to ensure uninterrupted operation of energy systems.

By integrating partial discharge monitoring, GIS units can operate more safely and reliably, minimizing service interruptions and extending their operational lifespan, which is especially crucial in critical infrastructure.
Region Analysis:
North America Leads With 35% Market Share in the Partial Discharge Monitoring Systems Market. Partial discharge monitoring systems are used to detect tiny electrical discharges that occur within the insulation of high-voltage equipment, such as transformers, switchgear, and cables. These discharges—called partial discharges—happen when insulation begins to degrade, often due to stress, contamination, or defects. If left unchecked, they can grow over time and eventually cause equipment failure, leading to costly downtime or even dangerous accidents. Partial discharge monitoring systems work by continuously observing electrical signals, ultrasonic noise, or electromagnetic waves emitted during these discharges. By identifying early warning signs, these systems allow engineers and operators to take preventive action before serious damage occurs. This is especially valuable in industries where high-voltage equipment is critical, such as energy, utilities, manufacturing, and aerospace.
