Event Details

Cost: $1645.

ENOSERV and instructor Robert Hafer have joined together to present the Advanced Relays training course.

Equipping the relay technician to function effectively in the world of “reliability standards” is the focus of this reasoned curriculum. This course will provide the technician with the knowledge to comply with reliability standard PRC-0051b. The instructor, Robert, brings 15 years of protection relay experience working in transmission substations and hydro, coal and gas generating plants. With his 24 years experience in power plant electrical maintenance and substation construction, Robert is able to speak the language of the trainees.

Topics covered:

Attend the class at the ENOSERV Training Facility in Tulsa, Oklahoma and you will receive presentations on:

  • NERC PRC-005 and what standards affect the relay technician
  • Analyzing major outages in the Bulk Electric System (BES) from 1965 to 2011
  • History of NERC and its relationship to FERC
  • Study of “Reducing Human Performance Errors” NERC Industry Advisory
  • Purpose of Reliability Standards / Reliability of the BES  - targets, SER, and event reports
  • Tools of the Relay Technician and reducing human error 

  •  Practical application of Symmetrical Components – the ground directional relay

  • R-X diagram, Mho circles and impedance relays

  • Micro-processor Relays –understanding logic and programming


You will learn:

    • How to recognize the human factor in work habits

    • The meaning of “Adequacy and Security” as it relates to the BES
    • Reliability standards the relay technician must know
    • How understanding rectangular to polar conversions, R-X diagrams, Mho circles, and Symmetrical components makes a better relay technician
    • What major substation components can affect the BES

    • How to set and test a electro-mechanical  ground directional relay

    • Calculating settings and testing of a KD-10 distance relay

    • Programming and operation of  a SEL-751A micro-processor relay

    • Understanding operation of a SEL-311C distance relay with logic diagrams


Prerequisites of this course include a math background in basic algebra and trigonometry. Students need a working knowledge of D.C. and A.C. theory with practical experience preferred in circuit analysis and troubleshooting. Previous exposure to protective relays is necessary. Knowledge of IEEE Device numbers will greatly assist the student in class exercises involving print reading. Students need to bring a laptop computer equipped with a serial port or a USB to Serial adapter and a handheld calculator.

ENOSERV training courses are held at the ENOSERV Training Facility. Only ENOSERV presents training on any type of test set with numerous electromechanical and digital relay types. All classrooms were built from the ground up with only relay testing training in mind. Refreshments and lunches will be provided by ENOSERV. Attendees should bring his/her laptop with RTS installed.

Class times are as follows: 8 a.m. - 5 p.m.
