Japanese precision since 1935


Your power inverter’s effi ciency is


more than 100 %?


If your power inverter measurements show an effi ciency of more than 100 % or if the measured values simply sound too good to be true then the reason is very likely a measurement error cau- sed by phase shift.


Every current sensor produces a gradually in- creasing phase error in the high-frequency region which can make precise measurements on SiC & GaN based applications quite diffi cult.


HIOKI products can compensate this phase error because we make both power analyzers as well as the specially designed current sen- sors. This ensures that your power measure- ments at high currents and high frequencies are as precise as you can expect them to be.
