The big problem is the protective ground.
Many times it is overloaded or not constructed for handle these pollutions. The safety ground can handle
a real “bang” of 110-220Volt and X Watts without any problems, but when it comes to these small currents of
some Milli V with very high frequencies it doesn’t always catch them. And if it catches them, it many times
doesn’t get rid of them.
So, in fact, it can be the opposite. The protective ground can leak back HF pollutions to the net.
These pollutions will flow around in the power system searching for a place to ground and fade away.
And places as your TV or your HiFi system, with all the cables and magnetic fields load up them. The pollutions
have simply nowhere else to go. They flow around there in their search for ground and peace.
Current goes in and current goes out of switched devices and lighting fixtures of every kind.
All of these make the current messy. Not least computers with their switched power units, chargers for mobile telephones, all the halogen and LED lighting, dimmers etc. all cause a great deal of high-frequency noise, stray voltages. and magnetic fields.
This noise seeks the easiest path to the earth. And since these pollutions can be everything from 50-60 Hz to very high-frequency, weak, currents, it is not often that the path of least resistance is via the protective earth.These currents instead can find dishwashers, laundry machines, counter tops with waterpipes,etc.
Your HiFi rack and stereo set with all the cables and devices are a most attractive place.
Moreover, these high freq often generate magnetic fields that absolutely have influence and bad impact on the sound reproduction.
Why use Entreq Ground Box’s ?
A clean, solid and fixed ground point is the most important factor for precision!
The ground should be Zero. A clean, solid fixed point. A fixed point where everything in the power net can refer to as Zero. But sadly, it is far from that in reality.
We normally say 220V 50Hz alternative110 V 60Hz. But there are a lot more frequency on the power net. These is caused by the way we connect zero and protective ground together in the main central/fuse boxes and all devices we connect to the power net. All together this cause a lot of unwanted magnetic fields that distore.
