Industry & Occupation
Classification
Summary
Specialist who inspects insulation, continuity, operating characteristics, etc., of distribution boards and switchgear using various testing instruments to ensure safety and reliability.
Description
Switchgear inspectors conduct insulation resistance tests, withstand voltage tests, contact resistance measurements, partial discharge tests, and operational tests on switchgear such as distribution boards and circuit breakers to evaluate equipment performance and safety. They record test results, compare them with standard values, detect abnormalities, and arrange for adjustments or repairs as needed. They use specialized equipment such as meggers, withstand voltage testers, micro-ohm meters, and partial discharge measurement devices, and are required to implement safety measures under high voltage and strictly adhere to work procedures. Work sites include factories, power plants, substations, etc., and they handle periodic inspections, troubleshooting, and inspections associated with renewal projects.
Future Outlook
Stable demand is expected due to the renewal of aging infrastructure equipment and the introduction of predictive maintenance technologies. Adaptation to inspection and diagnostic fields using IoT and AI will be key in the future.
