Elevify advantages
Develop skills
- Size three-phase transformers: apply MVA, kV and current formulas on the job.
- Read substation one-lines: interpret symbols, power flow and switching paths fast.
- Configure vector groups: choose delta or wye links for grounding, faults and harmonics.
- Set transformer protection: pick CT/PT ratios, relay pickups and fault limits quickly.
- Run field checks: perform phasing, polarity, oil and insulation tests before energizing.
