Due to this, study needs to be carried out to investigate the harmonic distortion
causes by non linear load so that solutions can be designed.
It could be noted that the value of the total harmonic distortion
is of higher percentage without using filter .
The electrical engineering society is pressuring users responsible for generating harmonic distortion
to help in clearing it up, according to Cherney.
Until recently, the switching power supplies within these devices had a low power factor and generated harmonic distortion
back into the power distribution system (not unlike the traditional UPSs used to power them).
Electricity bill is also reduced by reducing harmonic distortion
in the power supply.
The measured results of harmonics magnitude, individual harmonics distortion and total harmonic distortion
of different UPSs are shown in table 2, 3, 4, 5 and 6.
can be determined by following equations:
Also, the notch filter can introduce harmonic distortion
of its own.
5 dB) at 1 KHz, the RBB-04B-PS has maximum total harmonic distortion
of 5 percent.
The M8190A is a modular arbitrary waveform generator that delivers simultaneous high resolution and wide bandwidth with a large spurious-free dynamic range and low harmonic distortion
The units exhibit <5 percent total harmonic distortion
at full load, current limiting, short circuit protection, surge protection, and thermal shut-down with automatic recovery.
99, low total harmonic distortion
(THD) of less than 10 percent, and also precise DC bus regulation within a tolerance of 2.
