Automatic detection and isolation of snapped low-voltage overhead conductors.
A live wire on the ground draws < trip current in dry earth —
fuses and OC relays stay silent. People die. We fix that.
Capacitive E-field probe (non-contact, 50 Hz)
↓ STM32L4 / ESP32-S3 · SX1262 LoRa mesh
↓ quorum of neighbours must agree
↓ Gateway at feeder head
↓ Isolates in < 2 s
↓ Cloud observes · alerts · audits
No false trips in bench tests · < 5 mA avg · ≥ 300 m LoRa LOS · BOM < ₹1,800/node

Every demo runs a virtual 12-node LV feeder with a real arbiter.
No 230 V hardware is implied unless the M5 rig is on stage.
