Energy Manager Electrical JP

A study app for Japan's Energy Manager qualification, electrical field (エネルギー管理士 電気分野). This national qualification is based on the Energy Conservation Act; holders are appointed as energy managers at factories and other sites above a certain level of energy consumption. All 600 practice questions come with a clear explanation.

■ Subjects Covered (600 questions across 4 courses, 13 areas)

【Course I — Energy management and regulations】
• Energy Conservation Act and related orders (50) — purpose of the Act, duties of designated businesses, judgement criteria, reporting
• Energy situation, policy and fundamentals (30) — domestic and global energy supply and demand, units, energy conversion
• Fundamentals of energy management (40) — judgement criteria, management standards, measurement and records, improvement cycles

【Course II — Electrical fundamentals】
• Electrical and electronic theory (55) — DC and AC circuits, electromagnetics, electronic circuits
• Automatic control and information processing (45) — transfer functions, frequency response, sequence control, computing basics
• Electrical measurement (40) — measurement methods, instruments, error and accuracy, sensors

【Course III — Electrical facilities and machinery】
• Factory power distribution (75) — substations, protection coordination, power factor, harmonics, technical standards
• Electrical machinery (75) — transformers, induction and synchronous machines, DC machines, power electronics

【Course IV — Power applications】
• Motor drive applications (75) — load torque characteristics, motor selection, conveying machinery, pumps and fans
• Electric heating (30) — resistance, induction, dielectric and arc heating, heat pumps
• Electrochemistry (25) — electrolysis, batteries, surface treatment
• Lighting (30) — photometric quantities, light sources, lighting design, energy-efficient lighting
• Air conditioning (30) — moist air, heat load, HVAC systems, energy-saving techniques

Candidates choose either the thermal field or the electrical field; only Course I is common to both. To pass you need at least 60% of the marks in every course of your chosen field. A course you pass stays valid for three years, so you can build up course passes across several years rather than clearing all four at once. This app records your accuracy per subject automatically, so you can see how ready you are for the course you plan to take next.

The exam is held once a year, on a Sunday in early August. The official paper uses fill-in-the-blank answer-group selection; to make studying more effective this app reformats the same topics into five-option single-answer questions.
