Power Quality and Reliability

Power quality refers to the level of electrical supply quality, including voltage, frequency, and waveform. It is the measure of how well the electrical supply meets the needs of the devices connected to it. Power reliability, on the other hand, refers to the ability of the electrical system to maintain a consistent and uninterrupted supply of power to its users. It is the measure of how often and for how long the power supply is available. While power quality can affect power reliability, the two are distinct concepts. Power quality issues can cause power interruptions, but a reliable power supply does not necessarily mean that it is of high quality.
