Hioki Clamp On Power Meters are multi-channel power measuring devices utilizing clamp sensor input to accurately and safely measure power on single-phase to three-phase lines. The PW3365 power logger takes safety and convenience one step further by being the world’s first non-metallic contact power meter that utilizes completely covered voltage clips that can be attached to any part of a cable or busbar. Customers can now monitor power demand and other power parameters to aid in energy audits and validate energy saving measures without risk of short-circuit accidents, power interruptions, or bodily injury due to electrocutions.
Although technicians had to connect instruments to metal terminals in order to measure voltage when measuring power in the past, Hioki’s newly developed no-metal-contact voltage sensor makes it possible to measure voltage simply by clamping the sensor around an insulated wire. This approach completely eliminates the risk of short-circuits since metal never comes into contact with live components, and it simplifies the sensor attachment process even when terminals are covered since the sensor can be simply clipped around the cable without removing the cover.
Use the Hioki PW3365 Clamp On Power Logger to analyze the fundamental waveform up to the 13th order of harmonic components that are included in the voltage and current signals of 50/60Hz power lines. Display the total harmonic distortion (THD) and RMS and harmonic content of each harmonic order as a numerical list or graph. In particular, you can now safely and easily measure the 5th and 7th harmonic within the harmonic component which tend to have the greatest impact on power quality.
The PW3365’s Quick Setup feature guides you through the process of setting up the instrument for measurement, right up to starting measurement, to make even 3-phase power measurement a breeze. Since any mistaken connections will trigger a FAIL message, the feature also helps prevent measurement mistakes.
The PW3365 displays recorded measured values as a graph for convenient use in power management. In addition to instantaneous measured values, you can review maximum, minimum, and average values by moving the cursor on the demand and trend graph displays.
