Industry & Occupation
Classification
Summary
Technical position that supports the safe and stable operation of the power system through monitoring, testing, adjustment, and maintenance of protective relays (relays) in substations.
Description
Relay operators are responsible for monitoring, testing, adjusting, and maintaining protective relays (relays) at power company substations and similar facilities. They use SCADA systems and control panels to monitor abnormalities in current and voltage, and in the event of a fault, they quickly isolate and restore the system via the relays. During regular inspections, they perform operation tests and verify settings using relay test equipment, and conduct adjustments and reports based on fault history and test results. They collaborate with chief electrical engineers and operators to play an important role in ensuring safe and stable power transmission and distribution.
Future Outlook
With the introduction of renewable energy and the advancement of smart grids, protective relays will become more sophisticated and remotely monitored. Even as automation progresses, demand for specialized technicians is expected to remain stable.
