Term Definition
Power Quality The concept of powering and grounding sensitive equipment
in a manner that is suitable to the operation of that equipment.
Transient A sudden, non-power frequency change in the steady-state
condition of voltage, current, or both.
Amplitude In this document amplitude will refer to the percentage of
change from 100% of the RMS voltage and or current value.
Phase Angle In this document phase angle will refer to the number of
degrees between the phase voltages as well as the number of
degrees between the phase voltage and phase current.
Harmonics Sinusoidal components of periodic waves that have
frequencies that are multiples of the fundamental frequency.
The MPQSIM product creates 3
rd
and 5
th
order harmonics.
Flicker Flicker is a very specific problem related to human perception
and incandescent light bulbs. It is not a general term for
voltage variations. The MPQSIM product produces voltage
variations over time that will create Flicker phenomenon in
incandescent lighting.
Source The source of electrical generation or supply.
Load The load of an electrical generator or supply.
Line Frequency The fundamental AC frequency of the power network.
