The Hioki PW3360 is a clamp on 3-phase 4-wire energy power logger utilizing clamp sensor input to measure power on single-phase to three-phase lines.
Using two power loggers provides for the measurement and verification process: measurement between the distribution panel and utility meter for the amount of electricity sold to the utility and purchased by the customer simultaneously. The data enables confirmation of the PV system operating condition.
Computation of electricity charges is by inputting the unit cost (per kWh) so that the PW3360 can multiply the electricity charge unit cost by the active energy (power consumption) value.
The output of the power conditioner is measured to display voltage and frequency changes in order to verify correct operation of relays.
