FAQ's of Power Analyzer - KEW 6315:
Q: How can I use the KEW 6315 Power Analyzer for energy audits in three-phase systems?
A: Simply connect the analyzer's voltage test leads and clamp sensors to the appropriate R, S, T, and N wires in your three-phase/4-wire or 3-wire system. Use its automatic data capture, set desired logging intervals (as low as 1 second), and review results on the TFT display or transfer data to your PC for detailed analysis.
Q: What are the benefits of using the harmonic analysis feature on the KEW 6315?
A: The harmonic analysis up to the 50th order allows you to detect power quality issues such as voltage distortion or equipment inefficiencies. By identifying harmonics, you can take corrective actions to improve system stability and energy efficiency, which is crucial for maintaining sensitive equipment.
Q: When should I consider using the battery operation mode?
A: Battery operation is ideal when working in locations without immediate access to mains power or when continuous measurements are required during power interruptions. Simply equip the analyzer with its optional internal rechargeable battery before heading to sites where AC outlets are unavailable.
Q: Where can stored measurement data from the KEW 6315 be accessed or transferred?
A: Collected data is saved to the device's SD card, which can be reviewed on the analyzer itself or transferred via USB or RS-232C ports to a PC. The included PC software helps organize, visualize, and analyze the recorded data efficiently.
Q: How does the recorder's interval selection process work?
A: During setup, you can select from recording intervals ranging between 1 second and 1 hour to suit your application. This flexibility allows you to capture fast transients or long-term trends depending on your measurement objectives.
Q: What environments is the KEW 6315 suitable for, regarding temperature and humidity?
A: This analyzer operates reliably in temperatures from 0C to 50C and can be stored within -20C to 60C. It is rated for relative humidity up to 85% (non-condensing), making it apt for most indoor and field environments without excessive moisture.
