Recent years, industrial motors are preferred to be switched to high efficiency motors from traditional general purpose motors to reduce energy. Large air heaters in public facilities are switching to high efficiency motors from traditional general purpose motors. In other hand, issues have occurred after installation in the market.
Though the cause of these issues may vary, one of the main causes is the high inrush current. High efficient motors have higher output and rotating speed than general-purpose motors which leads to high electric current value. Inrush current up to 5 to 10 times the stationary current can be expected for induction load of a motor in general, but in high efficiency motors, the amount of electric current will be larger (Ex. up to 170Apeak in 2.2kW motor).
Since high accurate electric current waveform can be measured by combining DL850E and the current probe, by precisely understanding the transient change of electric current and the inrush curr ent peak value, issues can be resolved more quickly during installation by verifying features of high efficiency motors.
ScopeCorder DL850E combines a mixed signal oscilloscope and portable data acquisition recorder into a modular platform designed to capture both high-speed transients and low speed trends. Using flexible modular I/O with built-in signal conditioning, precisely measure electrical, physical sensor signals and CAN/ LIN / SENT serial bus for applications ranging from R&D research to in-vehicle data logging.
