HIOKI PW3360-20 Power Logger Kit 500A | 3-Phase Energy Log

The HIOKI PW3360-20 power logger is purpose-built for extended energy monitoring and load profiling on 3-phase electrical systems. By clamping non-invasively around existing conductors, it logs power data over hours, days, or weeks without interrupting the electrical supply — making it the right tool for energy audits, demand analysis, and tariff optimisation projects.

This kit includes 500 A clamp sensors that cover the majority of LV distribution feeders and sub-distribution boards in commercial and industrial installations. Logged data is stored on an SD card and transferred to a PC via USB for analysis using HIOKI’s included software. The ability to log power factor alongside active and reactive power gives energy engineers the data they need to identify power factor correction opportunities and verify the performance of capacitor banks as part of electrical energy management programs.
