Explain power quality and EMC.
Answers
♦Power quality refers to the ability of electrical equipment to consume the energy being supplied to it.
✔ A number of power quality issues including electrical harmonics, poor power factor, voltage instability and imbalance impact on the efficiency of electrical equipment.
♦EMC is the term used to describe how well a device or system is able to function in an electromagnetic environment without introducing electromagnetic disturbances that interfere with the operation of other electrical products in the environment
The area within the field of Electromagnetic Compatibility (EMC) focusing on the operation of power distribution systems including connected equipment without any malfunctioning is called Power Quality (PQ). Two entities are involved in PQ:
the grid operator, and
the users of electrical power.
