Ultrasonic Testing (UT)

Ultrasonic Testing (UT) is a non-destructive method using high-frequency sound waves to detect defects, measure thickness, and assess material properties. In electrical inspections, UT is vital for detecting partial discharges (PD), insulation degradation, and defects in transformers, cables, and switchgear. It identifies arcing, corona, and mechanical issues like loose windings or circuit breaker misalignments.

UT excels in preventive maintenance, enabling early detection of faults, reducing downtime, and enhancing safety. Its advantages include being non-intrusive, highly sensitive, and capable of real-time monitoring. However, it requires accessible surfaces, skilled operators, and noise-controlled environments for accurate results.

Applications include monitoring insulation health, locating PD, ensuring cable integrity, and detecting issues in high-voltage systems. UT is an effective tool to maintain reliability and extend the lifespan of electrical equipment, making it indispensable in modern maintenance strategies.
