## NETA Level 2 Study Tips December 2019

I recently took my level 2 along with a few other guys where I work. Not everybody passed but here is what was on our tests. Some of this may already be posted in other threads but other parts are new:

Test focused mainly on math, transformers, relays

Picture of main tie an asking if a switch will open when tie opens

Relay numbers, what does this device do?

Basic ANSI device numbers (know 21,27,32,50,51,52,59,87)

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

Differential relaying theory (basics)

Not much on safety, two confined space questions

What defines a confined space?

Can someone attend more than two manholes?

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

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

One guy said no questions on 1910.137

Know PCB reporting requirements - 10 pounds

protective ground sizes and functionality

LOTO process

How much torque at this horsepower?

Basics of thermography (emissivity etc)

Looking at infrared image, no temp points, just scale. Approximate the temperature in the area indicated.

600a real power with theta angle, what is the reactive power?

Know how to find kVARs

Know how to find power factor

Know your power triangle in general

CT polarity and gf scenarios, what is the secondary current, is this wired properly

Bar type ct picture in a switchgear with an arrow asking what is this

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

Circuit breaker one-line symbols

Where to test on a switch for contact resistance, point 1 and 9

Basic kirchhoff law, proportional calcs

What color sticker for acceptance? white

Diagram with open contact on top and closed contact on bottom, type c or class c

Voltage drop across resistors in series and parallel

Total resistance calculations in very basic circuits

What is the total inductance? Series and parallel

Know contact resistance and how it works

Ductor readings - which one is acceptable?

Generator testing

One line drawings in general

General knowledge of power factor testing

Ground testing (know the values in ohms)

Understand grounding principles

One or two questions on fiber optics

Know the value (15%) in which fuses fail

Read your MTS and ATS! Quite a few questions lifted straight from those two.

Know medium voltage testing requirements

NEMA enclosure ratings

Familiarize yourself with anti pump characteristics and blow out coils

% allowable for transformer winding resistance

What properties transformer oil shows when it has arced / broke down?

Know the uses of meters and the leads associated
