The process is similar to a doctor using a heart monitor to record the electrical signals for your heart. This type of test equipment will provide information used in evaluating if the electrical power is of sufficient quality to reliably operate the equipment. We can verify the power quality by installing a special type of high-speed recording test equipment to monitor the electrical power. On the other hand, if the electrical equipment malfunctions, is unreliable, or is damaged during normal usage, we would suspect that the power quality is poor.Īs a general statement, any deviation from the normal voltage source (either DC or AC) can be classified as a power quality issue. If electrical equipment operates correctly and reliably without being damaged or stressed, we would say that the electrical power is of good quality. Power quality is simply the interaction of electrical power with electrical equipment.
