WHAT IS POWER QUALITY?
Power quality is a measure of the strength and stability of an electrical power supply. It is often expressed in terms of voltage, which should remain within a certain range to avoid damaging electrical equipment. Power quality can be affected by a number of factors, including surges and fluctuations. To ensure reliable power quality, generator operators must monitor the generator and take steps to mitigate any potential problems.
Each piece of electrical equipment will have parameters for normal/safe operation, and guidelines as to how far from normal they can vary before power quality is deemed too low.
Whilst fluctuations in voltage etc. will always occur, these fluctuations must be kept within well-defined limits to ensure that equipment that draws power from a generator is safe and protected from damage.
