SA2100 Class S Power Quality Analyzer Overview SA2100 is a handheld multi-functional device which is designed to measure and analyze single or three-phase power system. This portable class S device can provide safe, convenient and accurate measurements for troubleshooting power networks. SA2100 Portable Power Quality Meters Portable Power Quality Meters enable electricians and facility maintenance professionals to troubleshoot and benchmark power quality problems over time. They help you identify energy waste in your facility and detect and prevent power problems before they occur. Why do you need Power quality meter analyzer? Portable Power Quality Meter identifies power quality problems that often manifest themselves as dips, spikes, harmonic distortion, imbalances, flicker and transients. Power quality determines the suitability of electrical energy to drive motors, machines and other end-user equipment. Poor power quality can affect the ability of these devices to operate properly, which can lead to malfunctions, premature failures or possibly cause them to not work at all. Most power quality analyzers monitor total harmonic distortion, phase angle, power factor, balance, etc. to get a complete picture of the system.
