The safety and quality of

undoubtedly important. If
you want to define the
quality of the energy simply
At the point, the amplitude

no quality assurance and

before use because it
requires continuity and
cannot be stored. Produced
for this reason
energy
needs to be high quality and
reliable. Unfortunately, the

that is produced to the
consumer.

the system frequency to be

the system frequency is
below 50 Hz.
The active

increased by means of the

thought turbines and the
frequency is stopped at a
value below 50 Hz.
In
this value, the frequency of

Before starting the test,
