Classification

Summary

Technician who inspects, maintains, and repairs substation equipment in transmission and distribution networks to support safe and stable power supply.

Description

Substation maintenance technicians target equipment such as transformers, circuit breakers, and switchgear installed in substations and distribution networks. They conduct inspection tasks including insulation withstand tests, temperature measurements, and dissolved gas analysis in oil to early detect deterioration or abnormalities, repair and adjust them to maintain power equipment reliability. They also engage in maintenance tasks such as equipment disassembly and cleaning, parts replacement, high-voltage testing, and control circuit adjustments, while implementing safety measures and record management in compliance with laws and standards. On-site work requires high-altitude operations, heavy machinery handling, and teamwork.

Future Outlook

Demand for renewal and maintenance of aging transmission and distribution infrastructure is on an increasing trend, making the securing of specialized technicians a challenge. Along with the introduction of new high-voltage equipment technologies, knowledge of automation and remote monitoring systems is also required.
