About this exam

The PGCIL Field Engineer & Diploma Trainee recruitment examination is the selection route through which Power Grid Corporation of India Limited hires engineers and diploma holders into roles that keep the national transmission network running - field engineering, substation operations and maintenance, and trainee positions that feed into them. It suits candidates with a diploma or degree in electrical engineering who want a public-sector career in EHV transmission rather than generation or distribution. The paper is a single-format multiple-choice test weighted heavily toward core electrical engineering, with substantial shares for power systems, protection and switchgear, machines and transformers, and transmission line and substation practice. The remainder tests power electronics and drives, instrumentation and control, general aptitude and reasoning, English, and current affairs with professional awareness. Because the technical domains carry roughly four-fifths of the marks, preparation should be built around them first, with aptitude and language kept ticking over through short daily practice rather than last-minute cramming. Work through standard electrical engineering textbooks for concepts, then solve numerical problems under time pressure, since the paper rewards speed and accuracy on calculations as much as recall. The official body publishes the current notification with the authoritative details on eligibility, vacancies, test structure and dates; always treat that notification as the final word.

What you'll study

Common questions

About PGCIL Field Engineer & DT preparation

What is the format of the PGCIL Field Engineer & Diploma Trainee exam?

It is a computer-based or OMR multiple-choice test with a single correct option per question and no descriptive section. Negative marking applies to wrong answers, so blind guessing costs marks. The official notification for your recruitment cycle states the exact structure, so confirm there before you plan your attempt strategy.

How difficult is the paper?

The technical questions sit at a solid undergraduate or final-year diploma level: standard, well-known concepts rather than obscure ones, but applied through numericals. Difficulty comes from breadth and time pressure, not trick questions. Candidates who know fundamentals cold and can compute quickly usually find it manageable; those who only memorised formulas struggle.

Can I retake the exam if I do not qualify?

There is no limit on the number of recruitment cycles you may apply to, provided you still meet the age and qualification criteria each time. Within a single cycle, though, you get one attempt. Check the current notification for age relaxations and eligibility conditions before applying again.

How much time do I need for each question?

Aim for roughly a minute per question on average, banking time on quick factual items to spend on circuit and machine numericals. Practise with a timer so you learn to abandon a calculation that is running long. The official notification gives the actual duration; build your speed target around that figure.

In what order should I study the subjects?

Start with electrical engineering fundamentals and machines, because power systems, protection and transmission topics all rest on them. Then take power systems and switchgear, followed by power electronics, transmission and substation practice, and instrumentation. Keep aptitude, English and current affairs as short daily sessions throughout rather than a separate phase.

What are the most common reasons candidates fall short?

Three recur: neglecting aptitude and English until too late, so easy marks are lost; memorising formulas without practising numericals, which collapses under time pressure; and over-guessing despite negative marking. A fourth is skipping the notification, leading to eligibility or document mistakes that nullify an otherwise good performance.

Are there interviews or other stages after the written test?

Selection typically involves the written examination followed by document verification, and some recruitment cycles include an interview or a trade or skill assessment for certain posts. The stages, weightings and qualifying criteria vary by cycle and post, so read the current official notification carefully rather than relying on previous years.

Where do I find the official exam dates and eligibility details?

Only on the official PGCIL careers portal and the recruitment notification published there. Question counts, duration, qualifying marks, fees and dates change between cycles, so this page deliberately does not quote them. Download the notification for your cycle and treat it as the single authoritative source.

How should I use mock tests in the final month?

Take full-length timed mocks twice a week and analyse every wrong answer by topic, not just by score. Keep an error log of recurring mistakes and revise those topics before the next mock. In the last week, shift to light revision of formulas, key constants and current affairs rather than new material.
