Automated High-Current Short-Circuit Test System for IEC 60898-1:2015 MCB Compliance.

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.
