15 relay technician skills for your resume and career

1. Transformers

A transformer refers to a passive electrical gadget that transfers electrical energy from one electrical circuit to the next.

Here's how relay technicians use transformers:
  • Traveled with company and put substations into service by wiring cabinets, transformers, and breakers.
  • Involved the wiring and testing of control relays, transformers, and breakers and switching gear.

2. SCADA

Here's how relay technicians use scada:
  • Focus on SCADA instrumentation and electrical systems to monitor plant operations.
  • Service, Backup, and Maintain SCADA, Domain Controller, & SQL Historian Servers.

3. Test Equipment

Test equipment is a mechanical tool or a device which is used create signals and gather response from an electronic device under test. It helps in detecting any faults in the device and it also proves the proper operation of the electronic device.

Here's how relay technicians use test equipment:
  • Learned how to use relay test equipment such as doble, omicron, sell, basler, beckwith, ge.Koontz Electric
  • Diagnose faults or malfunctions to determine required repairs, using engine diagnostic equipment such as computerized test equipment and calibration devices.

4. Substation Equipment

Here's how relay technicians use substation equipment:
  • Assist in testing, installing and maintaining relays, RTU and various substation equipment.
  • Helped perform substation switching for testing/repair of substation equipment.

5. Protective Relays

Here's how relay technicians use protective relays:
  • Test and commission substation and power plant protective relays, equipment, and control circuits.
  • Install, maintain, test, & repair protective relays on high voltage substations.

6. Control Circuits

Here's how relay technicians use control circuits:
  • Tripped checked DC control circuits.
  • Create and modify such control circuits if requested.

7. Capacitors

Here's how relay technicians use capacitors:
  • Wired substation breaker relays and CT panels Test, repair, and paints electric transformers, switch gears, and capacitors.
  • Performed periodic maintenance on reclosers, regulators, capacitors and tap changers.

8. Maintenance Procedures

A maintenance procedure refers to a thorough list of steps that details the way a maintenance task needs to be performed. It also acts as a documented standard that should be maintained when performing the task or job.

Here's how relay technicians use maintenance procedures:
  • Tested and performed maintenance procedures on the emergency diesel generators electrical systems.
  • Perform maintenance procedures for Wind Energy farms.

9. Doble

Here's how relay technicians use doble:
  • Experience with 3 phase relay test set (Pulsar, Megger, Manta, or Doble)
  • Recommended and initiated modification and replacement of equipment that failed to meet acceptable operating standards, based on Doble test results.

10. Control Systems

Here's how relay technicians use control systems:
  • Assured the effective commissioning of protective relay and control systems.
  • Performed troubleshooting repair, calibration and general maintenance of large industrial plant operating and control systems using schematics and logic drawings.

11. Transducers

Here's how relay technicians use transducers:
  • Perform testing on Relay's, CT's, Transducers, and equipment for 13.8kV switchgear.
  • Install various styles of pressure transducers / flow monitors and level controllers.

12. Switches

Here's how relay technicians use switches:
  • Program routers and switches to allow secure intercommunication networks.
  • Removed and installed pressure transducers and differential switches.

13. NERC

Here's how relay technicians use nerc:
  • Perform North American Electric Reliability Corporation (NERC) compliance testing on relays and battery banks.
  • Perform NERC compliance relating to system protection.

14. Scheme

Here's how relay technicians use scheme:
  • Verify that overall utility relay protection scheme matches original elementary protection scheme design.
  • End to End" tested the SEL-421 POTT protection scheme and the AMETEK Pulsar UPLC power line carrier communication.

15. Safety Rules

Principles or regulations that ensure the protection of people, objects, or the environment are called safety rules. These rules can be governing actions, devices, or procedures that help in minimizing the risks of loss, injury, or damage.

Here's how relay technicians use safety rules:
  • Comply with all company safety rules and procedures.
