The great Robert Carradine has gone. Naturally I spun the Nerds soundtrack this evening ☺️

The GB system ran this way from 1881-1926 ish and it proved inefficient so we built a so-called national grid instead. It’s given me a good living! I find trends do come full circle in history. Let’s see how this one pans out eh

Fitted an annunciator today in Essex. A “spare” unit was donated from London, pending a new one from the OEM. Another transformer back in service and pumping amps to society 💪🏻

Fans. Cooling fans. And possibly the odd tube train trundling along above

The chamber underneath a substation

Thermal expansion

40 metres (248 steps) under our capital are arterial cable tunnels carrying the Supergrid MIS circuits around and through London. I’ve spent much of the last 15 years building them, commissioning them, maintaining them, and showing the odd party of politicians around 💁🏻‍♂️😘

Simulated a mesh corner fault after some trip relay reset mods. Long day.

One disconnector automatically isolates and the two mesh bus section disconnectors sequentially isolate as the mesh corner is locked out. More people need to grasp the difference between auto and sequential isolation 💪🏻☺️

It’s a transition from two double circuit routes going north - south to a single east - west double circuit route. The way the circuits were strung out of Dungeness 400 means one of the Sellindge circuits needs to fly over one of the Ninfield circuits. Duck unders / flyovers are quite common

@engineerlondon.bsky.social I was in Lydd (near Dungeness) recently and there’s a section of 400kV line that dives under another. I can’t work it out, but I’m sure you know the reason.

Such hallowed ground on which we tread 🙏🏻

Smokey 🚬🚬🚬💨💨💨💨

Holiday in Britain folks. The beer is much better anyway 😆🍺🍺

Flexed my culinary fingers today. Homemade English muffins and hollandaise sauce for a stella Eggs Benedict. 😋🤤

AEI A Unit MCU removed from service 2009. On my office wall 💪🏻

From everyone at GMB - we wish you all the best for 2026!

2025 has been a historic year for clean energy in UK, with renewable project approvals reaching a record-high 45 GW — nearly double of 2024.

This surge was driven by an exceptional rise in battery storage capacity, which almost doubled to 28.6 GW, alongside strong growth in offshore wind & solar.

Tidying up my man cave with a Fullers BR1 by @fullersjohn.bsky.social 👌🏻

Still drinking beautifully 😍 Sure it’s got darker and stronger but the single malt notes are coming through nicely. Only got half a case left now. But one cannot take good beer with one 🤷🏻‍♂️🍺🥰

New fairy / Angel for our tree 🌲

Reclaim time on a T4DA1 J Unit

Always have a variety of lolly pop sticks in my line of work

The electrical widow and idol of my life in front of England’s only Grade II listed transmission substation 😍

@engineerlondon.bsky.social - saw this and thought of you... Since I first saw your feed I have become an engineer in corporate and now know exactly what you, and this book, mean 🤣

The perfect beer before a transient feeder simulation with reversion and hot standby auto close 👌🏻 As our saviour taught us- TPSO be damned!!!

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 💪🏻

Transient feeder fault with FR. Double F3 flap to quench and then auto restoration. This is what it’s all about 💪🏻🙌🏻👌🏻😍

Morning ☀️😘

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