The one thing this statement is about — a 10,000 A fault current — cannot be produced safely or affordably outside a dedicated test laboratory, so unless your institution already has one this is unanswerable rather than merely hard.
What it actually is
Before a miniature circuit breaker can be certified, it has to be tested by deliberately hitting it with a fault current of up to ten thousand amps to check that it trips safely. Doing that by hand is slow, imprecise and dangerous for the operator. The ask is a machine that sets up and runs those tests automatically to the international standard.
What to build
An automated test machine as specified by the statement: a transformer-based high-current source delivering up to 10,000 A, an automatically switched resistive and inductive bank that sets circuit impedance to achieve the power factors the standard requires, a test station with universal mounting for single pole, SPN, DP, TP and FP breakers rated 0.5 A to 63 A and an arc chute for containment, a PLC or industrial PC control and data acquisition system capturing high-speed current and voltage waveforms and computing peak let-through current and I²t, an HMI for parameter entry and automatic report generation against IEC 60898-1:2015, and integrated interlocks and safety systems.
Smallest thing that wins the room
There is no safe or achievable version of this demo — a 10,000 A fault current source cannot be built or operated in a hackathon environment.
How crowded this one gets
A guess, projected from the 2025 statements — the last year where both the submission counts and the winners were published.
Quieter than 88% of the 226 · #28 of 226 by expected field
Few teams are likely to go here. The best odds on the board come from statements like this.
Why: central ministry statements sat below the average; hardware halves the field a software statement gets.
This is a guess, not a fact
Nobody has published 2026’s numbers yet. This is an analysed estimate from last year’s pattern, so please do not take it as the truth — check the live counter on the SIH portal before you decide anything. The range covers the middle half of likely outcomes, so one statement in two lands outside it. Entry closes at 500 ideas per statement, so no range goes past that — a statement that reaches the cap fills and shuts rather than drawing an unlimited crowd. The model reads only three things a team can see before choosing — software or hardware, the theme, and what kind of body posted it — and those explain about a quarter of the variation in last year’s field sizes (R² 0.25 on held-out statements). Trust the band more than the number, and the ordering more than either. It cannot see how good your idea is, which is the part that actually decides it.
The scores
The number is the shorthand. The line under it is the reason.
Acceptance potential
1/5A genuinely poor pick and worth saying plainly — the core capability is unbuildable and unsafe outside a purpose-built test lab, and the standard removes every trace of innovation freedom, so the best possible submission is a control system attached to equipment that will never exist.
Feasibility
1/5A 10,000 A short-circuit test facility does not exist on a college campus and cannot be built on one — the source transformer, the switched impedance banks and the containment are industrial capital equipment costing crores, and generating fault currents of that magnitude without a purpose-built lab is genuinely dangerous rather than merely difficult.
Innovation scope
1/5IEC 60898-1:2015 fixes every test parameter — the current values, the power factors, the test sequences, the tolerances and the pass criteria — so there is no design freedom at all; the standard is the specification and your job would be compliance, not invention.
Clarity
5/5Exceptionally precise — it names the breaker configurations, the current rating range, the peak test current, the impedance module, the measured quantities and the control architecture, leaving nothing about the machine open to interpretation.
Effort
MassiveA high-current source, automated switched R and XL banks, a universal test station with arc containment, a high-speed data acquisition system, PLC control, an HMI and a compliance reporting layer is a capital equipment build that instrument manufacturers deliver over many months.
Demo-ability
HardThe defining condition is a 10,000 A fault and it cannot be reproduced at any scale that means anything — a low-current mock-up with the same control logic demonstrates the automation but proves nothing about the test the statement exists to perform.
In its favour
- Green flag: The standard removes all requirement ambiguity — if you can access the equipment, exactly what to build and to what tolerance is fully defined
- Green flag: The control, acquisition and automated reporting layer is genuinely buildable at low current and is a legitimate contribution if you are candid that you are demonstrating the automation rather than the test
- Green flag: Almost no team will attempt this, so a submission from a college with a genuine high-power electrical lab would be close to unopposed
Against it
- Red flag: Generating 10,000 A requires a purpose-built short-circuit laboratory; this is not a budget problem you can engineer around and attempting it improvised is a serious safety hazard
- Red flag: IEC 60898-1:2015 prescribes every parameter, so innovation scope is effectively zero and the panel has nothing to reward beyond execution
- Red flag: The standard itself is a paid BIS or IEC document, so even reading the full specification you are being asked to implement has a cost and access barrier
- Red flag: A scaled low-current mock-up does not demonstrate breaking capacity testing at all, and presenting one as if it did invites the most damaging kind of question
