Jost`s enginering co ltd presents power quality and flow recorders [pa-9plus] that are basically used for recording power quality and power flow parameters. They are perfect for power quality energy, investigation audits, load profiling, harmonics surveys/filter selection, substation monitoring, motor inrush current studies, load balancing and profiling. These instruments measures all power parameters from 1 hour down to cycles for single-phase, split-phase and 3-phase systems using 1, 2, 21/2 and 3 element wattmeter methods. They have voltages [line-line, line-neutral, neutral-earth], current, real power, reactive power, apparent poser, real energy, reactive energy, apparent energy, true power factor, displacement power factor, etc. A large hbaccklit liquid crystal graphic display confirms setup information and real-time status, phasors, frequency, true rms through 63rd harmonics, harmonic power, voltages, current, per phase and total power/energy data and minimum/maximum by phase real time clock. The pa-9 plus caters full reports, such as harmonic analysis report, harmonic trending, weekly energy report, tabular report [voltage & current], total harmonic distortion report, etc.
