Live labs
Full simulations to explore, not just a quick answer.
Open-ended simulation environments for exploring how power-system phenomena actually behave — built on real test systems and reference models, for whenever a single calculated answer isn't the point. A lab that runs on synthetic signals instead, as the Sense Lab does, says so at the top of its page.
Power system analysis
The IEEE 39-bus benchmark and a radial feeder: steady state, short circuits and dynamics, each checked against published reference results.
IEEE 39-Bus Power Flow
A full Newton-Raphson AC power flow on the canonical IEEE 39-bus (New England) test system, bundled with the standard model. Scale load, switch a line out for an N-1 study, toggle generator Q limits, and read bus voltages, line loadings and losses off the single-line diagram.
Method: Newton–Raphson AC power flow with N-1
IEEE 39-Bus Transient Stability
Transient stability on the same IEEE 39-bus system at three levels of fidelity — classical, with governors, or full GENROU + AVR + PSS — plus modal analysis — apply a three-phase fault at any bus, choose which line clears it, and watch every generator's rotor angle swing relative to the center of inertia. Includes a bisection search for the critical clearing time.
Method: Time-domain simulation, CCT search and modal analysis
Fault Analysis Lab
Symmetrical-components short-circuit analysis for a source-transformer-cable feeder — pick a fault type and location, then see the resulting three-phase waveforms and phasors before and after the fault.
Method: Symmetrical components and sequence networks
Sensors & high voltage
Partial-discharge sensing, followed from the core geometry to the signal that reaches the oscilloscope.
Flux Concentrator Core Geometry Lab
An interactive 3D exploration of toroidal sensor core geometry — closed ring, air gap, half-core and sector flux concentrator — and how much material you actually need, benchmarked against a published paper.
Method: Lumped reluctance model against published FEM results
PD Sensor Signal Chain Lab
What happens after a partial-discharge sensor picks up a pulse — HFCT transfer impedance, a published R-L output filter, and the trade-off between 50 Hz rejection and pulse fidelity, benchmarked against published data. Continues where Flux Concentrator Lab leaves off.
Method: Transfer impedance and filter frequency response
Sensing & communication
Which readings a sensor should send, and when: reporting rules compared on synthetic signals, with the message cost shown next to what the receiver still catches.
