Overview
The easy-to-attach CT6840A series clamp-style current sensors can be affixed without cutting the line under measurement. Due to this aspect of its design, it can measure current in applications where it's not possible to cut lines, including testing of EVs on chassis dynamometers and evaluation of operational solar power systems.

WLTP-compliant fuel efficiency evaluation testing
This series provides automatic phase correction for automatically correcting current sensor phase just by connecting to the Power Analyzer PW8001. This function automates configuration of phase correction values, a process that previously had to be carried out manually, eliminating settings errors and facilitating accurate power measurement. (All current sensors have phase characteristics, and the Power Analyzer performs phase correction so that power can be measured accurately.)

Solar Inverter (PCS) efficiency evaluation
In large-scale solar power systems like megasolar installations, extremely large currents on the order of 1000 A to 3000 A branch out and flow through two to four wires. Current values of each wire measured with the CT6840A series sensors can be added for the total current value using the box-type CT9557 sensor unit. The total current value will be output as one signal to allow evaluation of PCS efficiency
