TVSS a new twist

[patpappas]

Received a call this morning about a new TVSS that saves money in a new way, instead of lower clamping voltage there is a "filter" inside that changes transients and high frequency noise into heat and dissipates it off into the air instead of shunting to ground and returning possibly back on your electrical system, this allows all electronic equipment to operate cooler and last longer and delivers more pure 60 cycle sine wave. Anyone familiar with this?

The claims of saving money are bull, if it dissipates the surges as heat then it's still using energy.

However, there is (was) a brand of TVSS that claimed that by using filter caps and inductors it had better performance and better clamping that MOV's. It was a very pricey unit though...

I have heard claims that some TVSS offerings are pumped so full of capacitance they tend to correct power factor, but I tend to agree with the "bull" comment.

 

[patpappas]

I was just double checking in case I missed something but I believe in the "bull" comment also.

I think this kind of think was covered in another thread with much the same reaction.
I think the term "snake oil salesmen" was used to describe those who try to get you to buy such .......junk.

"delivers more pure 60 cycle sine wave" ?

how was it lost?

There is some extensive discussion going on in one of Mike Holt's newsletters about products that claim to save gobs of $$$ on your electric bills.

What is the name of the unit?

If it is a filter that dissipates heat, than it is diverting high frequency energy to resistors. Typically they put resistors in parallel with inductors or in series with some of the capacitors. This is actually good from an EMI control standpoint (reduces ringing and reflection of harmonics) but I have yet to see such a filter that doesn't also consume some line frequency energy as well. Such a filter would actually increase power consumption, not reduce it.

Power factor correction TVSS's are BS. The only thing I know of to help with the bill is to have the POCO set a delay on your meter circuit if you have backup power ( genset / UPS ) It will decrease your demand factor which will reflect in your bill.

Jumping the meter works, and rightly gets you in big trouble.

Like the Prius, the products of these 'New Energy (insert your favored buzzword)' do not save energy, just allow unscrupulpous hacks to relieve the eco-morons of their cash. So after all they serve their purpose.....

The unsolicited call is the "tip off". Can you imagine GE, Square D, Cutler-Hammer (etc) cold calling electrical contractors when they have a new product?

Like the Prius, D

Well, I don't much like the Pious car, sorry Prius.......but
The guy in the next office to me has a Lexus GS450h. A hybrid.
It's very quick - 0-60mph in under 6 seconds, electronically limited max of 155 mph.
It's amazingly quiet.
In fact, quicker, quieter and far more economical than say, a BMW 540.
For about the same price.
In my opinion, vehicle technology will move towards hybrid and eventually to electric.

So how long will the batteries last and what does it cost to replace them? What is the energy needed for manufacturing the batteries?

Two questions:

1. Does it still cost less to own for a lifecycle of the vehicle? Does the fuel saving offsets the extracost of batteries, replacement batteries?
2. Does it have a smaller 'carbon footprint' for its life?

Otherwise the Owner is making a choice that not only costs him more money, but actually have a larger impact on the environment.

My bet is on fuel cell.

I don't know the answers to all your questions.
The hybrid version at the time my colleague got it was ?10k ($20k at the exchange rate at the time) cheaper then the petrol/gasoline alternative.
Given that fuel costs will be lower and that indicated residuals are about the same in percent, it would be reasonable to conclude that cost of ownership of the hybrid version is lower than the petrol only equivalent by some margin.

Why it is cheaper to buy could be because it is cheaper to make. Or because fiscal policy reduces tax on the purchase of "green" vehicles.

On Fuel cells, my old friend "Rocket Ron" had something to say:

As far as vehicle emissions are concerned, it's clean.
The energy required to produce the hydrogen may not be so clean.

Oops, I forgot that in EU you don't deal with actual prices. The market is not free to determine the actual worth of things because undue Government interference. No wonder you produced Orwell.

Hydrogen is not the only fuel cell potential. Can't get any cleaner than nuclear energy. As soon as the CO2 binding and storage is economically solved the Zero emission coal plan wil beat the pants off of everything else. The Germans in WWII started making liquid fuel from coal and that technology is yet to be stepped up to current technology.
