Power quality problems aren’t always immediately recognisable. Without power quality monitoring, issues within electrical distribution systems and/or faults with equipment may be misdiagnosed as, for example, an old breaker that needs to be replaced. Misdiagnosis could lead to ineffective 'corrections', for instance, resetting the equipment or circuit. Spotting the signs of power quality issues early is essential to prevent further damage to systems or equipment. Once symptoms have been recognised, you can use a power quality analyser, such as Fluke’s 1770-Series Power Loggers, to monitor loads, voltage, current, harmonics, and unbalance or disturbance patterns.[1]
