This quiz is designed to reinforce marine transformer principles, kVA rating logic, voltage and current calculations, transformer efficiency, losses, star/delta connections, PI testing, safe isolation, protection and MCA oral-style transformer fault finding.
Explain transformer operation by electromagnetic induction and galvanic isolation.
Calculate transformer voltage ratio, turns ratio, current relationship and 3-phase kVA loading.
Explain why transformers are rated in kVA rather than kW and how power factor affects usable kW.
Describe transformer losses, efficiency, copper loss, hysteresis, eddy current loss and dielectric loss.
Define and interpret insulation resistance and Polarisation Index testing.
Apply safe isolation, prove-test-prove, discharge, earthing, CT safety and thermographic survey logic.
About this module
This module forms part of the TST Engineering Services E-Learning Recap Area. It supports structured MCA Engineering Oral Examination preparation by reinforcing transformer safety, transformer operation, burner management, transformer testing, blowdown, inspection, survey preparation and fault diagnosis. It does not replace tuition or mock oral practice; it is intended to strengthen revision, recall and weak-area identification.
