Does anyone have the above as advertised on the TV?

I do and thought mine was faulty as it does not hold its charge. Basically I charge it up for hours on end and then disconnect from the mains. After 2 or 3 hours its looses its charge, along with all the information I have programmed in.

I am now told this is normal - it is meant to be plugged in at all times apart from the odd time necessary to take it into another room etc.

Is it just me or does that seem silly that it has to be plugged in all the time using electricity? (I am told it uses only a small amount of electricity to be fair). Doesn't it defeat the object of saving electricity by having it plugged in constantly? It looks very portable, but really it isn't.

Power Factor is only considered on Three Phase Supplies as you don't get any current lag on single phase supplies.

This is untrue. Simply put "single phase power factor" into Google for a number of interesting explanations.

Sorry I thought we where talking about Domestic Installations. The words not considered come into place on Single Phase as we would we all have PF Correcetion Gear sitting at the Mains intake into our houses.

Power factor correction is now part of the design criteria with many power supplies used in TVs and PCs.

I think I undestand what you mean - It was just that the statement "you don't get any current lag on single phase supplies" drew my attention.When you have resitive, inductive or capacitive loads you obviously do.

PF correction has always been considered to some degree in domestic installations. That is why PF correction capacitors have been fitted to the older type of fluorescent lamp fittings which employ highly inductive coils for the past fifty years or so.

Due to the present cost of electricity more emphisis is being placed on PF correction both in domestic and industrial applications. However, as has always been the case in industry this will stop short of unity due to the laws of diminishing returns.

I will put this one to bed now so that anyone who wishes can return to the origional question.
