The 430 series 3-phase handheld power quality analyzers can measure all phases and the neutral and ground on virtually every connection in a low-voltage electrical distribution system for as many as seven hours. The analyzers are rated to CAT III, 1,000V and CAT IV, 600V for all four channels, which enables power quality service testing at the service entrance. Their measurement capabilities encompass all power system parameters including true rms voltage and current, frequency, power, power consumption, unbalance, and flicker. They automatically capture events like transients, interruptions, rapid voltage changes, dips, and swells, and the data memory stores as many as 50 screens and up to 10 measurements that consist of 32 parameters.
