    Questions and Topics I Remember From The NETA 2 Exam

    Hope this helps some of you. I took and passed the NETA II a few months ago and wrote this up shortly after. I believe it covers the NETA II test topics fairly well.

    Voltage drop across resistors in series and parallel

    Total resistance calculations in very basic circuits

    What is the total inductance? Series and parallel

    Ductor readings - which one is acceptable?

    A few pictures with items like a CT being pointed to and asking what it is

    Generator testing

    Basic ANSI device numbers (if you know 21,27,32,50,51,52,59,87 you should be covered)

    What is the purpose of the NEC?

    One line drawings in general

    Know how to find kVARs - Know your power triangle in general

    Know how to find power factor

    General knowledge of power factor testing

    Ground testing (know the values in ohms)

    One or two questions on fiber optics

    Know the value (%) in which fuses fail

    Basics of thermography (emissivity etc)

    Electrical rubber glove classes (max use voltage) and inspection dates

    Of course, read your MTS and ATS! Quite a few questions lifted straight from those two. My test focused mainly on medium voltage testing requirements.

    NEMA enclosure ratings

    Familiarize yourself with anti pump characteristics

    Blow out coils

    Differential relaying theory (basics)

    “When is it acceptable to wear cotton clothing?” In regards to voltage levels

    One or two questions on mechanical relays operation such as “pick up current was low, what setting needs to be moved” etc.

    % allowable for transformer winding resistance

    Know what properties transformer oil shows when it has arced / broke down

    Thank you!

    I took my first practice quiz today and was furiously writing down the things I didn't know.

    Thank you for such a comprehensive list!

    What do you mean by "Ground Testing (Know the values in ohms)"?

    I can't remember the answers options but these might help.

    This was a helpful write-up. I took my test today and passed. Just a few math problems but most things came from the ATS/MTS book. I had a lot of medium voltage questions. I think if you've been in the field, practicing NETA testing for the recommended amount of time, you should be good. A lot of basic knowledge questions. One word of advice that helps the most, cancel out the known wrong answers. This help immensely.
