Many congratulations Madeleine 👏🏻👏🏻👏🏻

(I showed you around London Power Tunnels a few years back- we are still energised ⚡️💡)

Simulated a feeder fault on the overhead line with Ferroresonance. An automatic suppression system quenches it by flapping the two 400 kV transformer disconnectors. This breaks the tuned circuit. After that, the circuit DARs as normal 💪🏻

I’d have to look into this… more Rob’s remit tbh and he’s been on holiday 😆

Most houses connect between one phase and neutral. Bigger comsumers will have a three phase supply

That’s air. Compressed air. Leaving the exhaust valves quickly and blowing away dust and contaminants

I like Translay-S because few know how to test it. Also the old EE DAR units are quite something/ VAR series of relays 👇🏻

Field equipment earth. Manages impressed voltage hazards 👍🏻
