NETA ETT Level 3 study plan

Draft a personal electrical safe-work checklist covering lockout/tagout, arc-flash boundary use, and temporary protective grounding, citing the specific rule behind each item

Calculate incident energy exposure from a supplied table of values and select the correct PPE category, showing your arithmetic

Build a one-page index of the codes and standards most cited on this exam (NFPA 70E, NFPA 70, NETA ATS, IEEE C57 series, IEEE 43, IEEE 81) and note which test each governs

Write 20 flashcards distinguishing approach boundaries, limited and restricted spaces, and when energized work is permitted

Match each measurement task (insulation resistance, winding resistance, contact resistance, turns ratio, ground resistance) to the correct instrument and its accuracy class

Explain how guard, remote, and shielded leads reduce leakage and surface current error in insulation testing

Compute insulation resistance readings corrected to a reference temperature of 40 C from a table of measured values and temperatures

Calculate polarization index and dielectric absorption ratio from given 1-minute and 10-minute readings and state pass/fail against IEEE 43 criteria

Sequence the standard transformer test set (ratio, excitation current, impedance, winding resistance, insulation, sweep frequency response) and justify the order

Compute percent impedance from short-circuit test voltage and current, and interpret deviation from nameplate

Convert measured winding resistance to a common reference temperature and compare phase-to-phase balance

Identify what excitation-current and turns-ratio anomalies reveal about core vs winding faults

Interpret a supplied sweep frequency response trace against a baseline and describe the likely mechanical fault

List the timing and travel measurements required for a circuit breaker and the tolerance source for each

Interpret a supplied dynamic contact resistance or travel-curve plot and name the mechanism fault it suggests

Explain how a primary-injection test verifies a protective relay and instrument transformer circuit end to end

Compute CT ratio and burden from given nameplate and test data, and check for saturation risk

Distinguish pickup, dropout, and time-delay settings for overcurrent relays and verify each against a coordination curve

Perform a fall-of-potential ground resistance test on paper: place probes, apply the 62% rule, and explain why spacing matters

Diagnose a cable insulation failure by comparing insulation resistance, time-domain reflectometry, and partial discharge evidence

Select the correct ground-fault protection scheme for a given system grounding arrangement and justify it

Interpret motor insulation resistance, PI, and surge-comparison results to recommend run, dry out, or repair

Explain how vibration, current signature, and winding resistance tests separate electrical from mechanical motor faults

Re-solve every missed question from the Week 4 quiz without notes and confirm the reasoning

Compare transformer and breaker test acceptance criteria side by side and note where standards disagree or are silent

Work through two scenario items that combine a failed test result with a required next action

Explain the safety implications of testing a breaker still connected to a live bus and the isolation steps required

Rehearse the safe-work checklist against three new job scenarios and note any gaps

Review measurement-instrument selection and error sources, then redo 10 mixed calculation problems cold

Recompute PI and temperature-corrected insulation values from fresh data without reference to earlier work

Identify the three domain topics you are weakest in and write a targeted 30-minute drill for each

Take two full-length timed practice exams under exam conditions and record domain-by-domain scores

Review only the lowest-scoring domain from each exam and rewrite each missed concept in your own words

Recite from memory which standard governs each major test type covered on the exam

Confirm logistics: approved references, calculator policy, and time-per-question pacing target
