Partial discharge measurement identifies tiny electrical sparks in high-voltage equipment insulation, preventing failures and ensuring system reliability. By detecting early insulation defects, it helps manufacturers, OEMs, and power sector professionals maintain safety, extend equipment lifespan, and reduce operational risks through timely maintenance and quality assurance.
What Is Partial Discharge Measurement?
Partial discharge measurement detects micro discharges in insulation systems of transformers, cables, switchgear, and other high-voltage apparatus. These small discharges indicate weak spots or defects that could lead to failure. Measuring discharge magnitude and patterns allows engineers to evaluate insulation health, prevent outages, and maintain reliable operation.
How Does Partial Discharge Measurement Work?
Testing applies high voltage to insulation while sensors capture electrical pulses caused by partial discharges. Digital peak detection circuits analyze these signals, providing precise fault location and severity assessment. This method enables early identification of insulation issues and supports preventive maintenance.
Why Is Partial Discharge Measurement Important for Manufacturers?
Manufacturers use partial discharge measurement to ensure product quality and reliability. Detecting insulation defects during production reduces returns, warranty claims, and safety risks. OEMs rely on this process to verify equipment performance before shipment, reinforcing customer trust and compliance with safety standards.
Which Industries Benefit Most from Partial Discharge Measurement?
Power utilities, substations, generation plants, high-voltage equipment manufacturers, railways, industrial factories, and certification agencies benefit significantly. It supports preventive maintenance, reduces downtime, and enhances safety across sectors that rely on continuous, reliable electrical systems.
When Should Partial Discharge Measurement Be Conducted?
Partial discharge testing is essential during production, installation, commissioning, and routine maintenance. Early detection allows timely repairs before severe damage occurs. Scheduled testing ensures system integrity, particularly for aging infrastructure or after electrical faults.
