In present power system, the measurement of power quality is becoming necessary due to
the presence of nonlinear and dynamic loads. This paper proposes a digital instrument …

The paper deals with the influence on the power quality of various light technologies and
measurement of their energy efficiency (lighting efficiency). A virtual power quality analyzer …

The paper presents alternative circuits for voltage-current converters to be used in the
calibrator of fictitious power. The experimental studies have revealed a number of problems …

This paper presents an electrical power source with arbitrary harmonics generating for
power quality measurement devices in calibration. Harmonics generating theory illustrate …
