About this exam

Vidyut Sahayak (Pareshan) contractual recruitment is a fixed-term junior electrical engineering engagement with a state electricity utility or board - typically a distribution or transmission company hiring diploma/degree electrical candidates for substation, O&M, metering and field work on a contract basis. The written test is objective: multiple-choice questions delivered on computer or OMR sheet, drawn from a single syllabus that spans the whole electrical discipline rather than one specialty. Weighting leans on electrical machines and power systems, with circuits, power electronics and drives, measurements and instrumentation, control systems, basic and digital electronics, installation and safety practice, renewable energy and energy conservation, plus a small general awareness, reasoning and language component. Because the engagement is contractual, the paper rewards candidates who are fast, accurate and comfortable with field-oriented practical content, not only with derivation. Preparation should follow the weightage: shore up circuit laws, phasors and three-phase fundamentals first, since machines and power systems both rest on them; then drill numericals in transformers, induction and synchronous machines, transmission parameters, protection and switchgear; then cover power electronics, instrumentation and control at working depth. Finish with installation, safety and renewable-energy topics, which are compact but often under-prepared, and keep a weekly slot for the language and reasoning section. The official notification remains the only authority on pattern, marks and eligibility.

What you'll study

Common questions

About Vidyut Sahayak (Pareshan) Contractual preparation

What is the exact exam format - computer-based or OMR?

Recruiting utilities have used both OMR and computer-based objective tests across cycles, and the single-paper versus sectional structure also changes. The notification and the mock link or instructions released with the admit card are what settle it. Practise both modes: OMR bubbling speed and on-screen navigation with a rough-sheet habit.

How many questions are there and how long do I get?

This varies by recruitment cycle and is not fixed across advertisements, so no reliable number can be quoted here. The recruiting utility publishes the question count, duration and section-wise structure in its official notification and any corrigendum. Read that document, including amendments, before finalising your attempt strategy and practice timings.

Is there negative marking?

Marking rules are set by the recruiting authority for each advertisement and are not uniform. Check the notification and the instructions printed on the admit card or shown on the test screen. If negative marking applies, switch to a selective attempt style: answer confidently known questions, leave pure guesses, and use elimination only where two options clearly fall away.

How difficult is the paper compared with other utility exams?

Difficulty is moderate, but breadth is the challenge - machines and power systems carry the most weight and are tested at a depth closer to a full semester paper than to a general aptitude test. Circuit fundamentals, three-phase concepts and protection basics recur. Expect numericals on transformer parameters, induction machine slip, transmission efficiency and short-circuit quantities.

Can I reappear if I am not selected?

There is no universal retake rule: this is a contract recruitment, so each advertisement is a fresh selection process with its own application window and eligibility conditions. If a new notification is issued, you generally apply afresh. Any restriction on repeat applications, service period or age relaxation would appear in that advertisement - read it before applying.

In what order should I study the syllabus?

Start with circuits and network theorems, phasors and three-phase fundamentals - they underpin everything else. Then take machines, then power systems including protection, since together they carry the largest weight. Follow with power electronics and drives, measurements, control systems and digital electronics. Close with installation, wiring, safety and renewable energy, which are compact and easily consolidated near the exam.

What are the most common failure modes in this exam?

Three recur: avoiding machines and power systems numericals and over-studying low-weight theory; memorising formulas without phasor and equivalent-circuit reasoning, which breaks under twisted questions; and treating installation, safety and renewable energy as optional. Unit and per-unit discipline is another quiet killer - wrong kVA or base conversion loses easy marks.

Will the language section be in Gujarati, English or both?

Utility recruitments in Gujarat commonly issue the paper bilingually, with Gujarati and English versions of the same question. The notification states the medium and whether a language test is qualifying or scoring. If the section carries marks, do not leave it to chance - practise comprehension and grammar in the medium you read fastest.

Do I need practical field knowledge to score well?

Not hands-on, but field-flavoured questions appear in installation, wiring, earthing, safety practice and protective device selection. Knowing why a starter is used, how earthing resistance is measured, or what an MCB curve means converts directly into marks. Study IS-style wiring practice and safety procedure alongside the theory, not after it.
