Start your Switchboards & Protections recap

This quiz reinforces shipboard power generation principles: three-phase AC, alternator frequency, excitation, AVR response, synchronising, power factor, load sharing, PMS logic and electrical protection.

Separate governor control from AVR/excitation control.

Calculate frequency and explain 3-phase alternator fundamentals.

Apply synchronising rules, lamp methods and out-of-phase hazards.

Explain power factor, kW, kVAr, kVA and alternator current limits.

Balance kW with governor controls and kVAr with AVR trim.

Diagnose voltage collapse, reverse power, earth faults and blackout scenarios.

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 power generation control logic, three-phase AC theory, synchronising discipline, power-factor interpretation and switchboard fault response.

How this recap works

This standalone quiz combines power-generation knowledge with oral-exam prompts, confidence tracking, smart recall and a final weak-area report.

Smart recall brings incorrect questions back a few questions later.
Flag questions on reverse power, bus-ties, HV/LV protection, breaker testing or synchronous compensation for later review.
Confidence tracking highlights guessed answers that need revision.
Oral Exam Focus boxes help convert technical definitions into MCA-style spoken answers.
The final report identifies weak areas across switchboard fundamentals, protection, breaker technology, synchronising, reactive power, PMS and survey testing.

Confidence Check

How confident were you that you could explain this answer verbally in an MCA oral?

Smart recall

Wrong answers are automatically reinserted a few questions later. The aim is mastery of fuel compliance, treatment and oral explanations, not just clicking through.

Oral exam mindset

After each answer, read the examiner note and oral focus. The goal is to explain the fuel property, the machinery risk, the treatment response and the regulation clearly, not memorise a letter.

TST support

Tuition, mock orals, call transcripts and e-learning recap support for MCA engineering oral preparation.
