23 HP 3 phase 400 Volts motor starting and running

What does a reciever for this system look like?

[RODALCO2007]

@conoba Excellent question, I make a video of one over the next few days

[RODALCO2007]

@conoba Look at my video - kWh meter Schlumberger - where a modern electronic version of the receiver is visible.

I upload a video as soon i find one of the older electromechanical ones in my basement.

@RODALCO2007

I would love to see the electromechanical ones. How old is this technology? Google and wikipedia didn't tell me much about the history.

First I got to know about this technology was some years ago. Every time at 6 in the morning the lamp balast in my aquarium would emit something that sounded like morse code. Really eerie. I investigated and found out that it is just the local power company switching a section of streetlights.

So the wee ripple controllers on most power boards/ fuse stations or near hot water cylinders read this signal pumped down the lines by this machine and turns on or off accordingly?

[RODALCO2007]

@produKtNZ Correct.

There are also solid state versions of these ripple plants.

In certain parts of Auckland a pilot system is also used and has additional control wires going into the meter box.

these 3-phase motors have such an intimidating windup sound... i love it!

This equipment is not much different from an old style motor-generator transmission system used for early voice radio transmission in the UK, except it transmits a 1050 Hz ripple over a transmission line through an enormous isolation transformer. The ripple is received by a device connected to a water heater and is used to control it.

wow thats one good ass motor last long while slowing down

[steamboy51]

Where abouts is this motor/control panel and what is it used for?

[RODALCO2007]

@steamboy51 used in a distribution substation.

[daewooparts]

good bearings, it better be its swiss made :P

[nothing4224]

I think you could get some more ponies out of that thing if you paint some flames on the side.

[RODALCO2007]

@nothing4224  LOL

[coondogtheman1234]

you should get a motor from an escalator and do a video on starting and running it.

BTW whats this motor here for?

[RODALCO2007]

@coondogtheman1234 I'm currently not working with escalators, this is for a ripple plant controlling hotwater signals.

@RODALCO2007 Hi Rodal, I'm fascinated but still a little confused about what this exactly does. Could you explain more or point me to a good website?

[RODALCO2007]

@SupaMellotron Google under Zellweger ripple plant, there are some reports about the latter.

This equipment is probably 30 years old and used for load shedding over peak demand periods.
