Highly Accurate, Broadband, Wide Dynamic Range Makes for Reliable Measurements Voltage Measurement Range Voltage Frequency Range Transient overvoltage Transient overvoltage detection Line-to-line voltage (3P4W) High-order harmonic measurement Line-to-line voltage (1P2W, 1P3W, 3P3W) Phase voltage (1P2W, 1P3W, 3P4W) 780V Harmonic measurement 1300V 6000Vpeak Both low and high voltages can be measured in a single range.
For a voltage of v1 applied at the non-inverting input and a voltage of v2 applied at the inverting input, the op-amp will produce at its output terminal a potential equal to the product of the open-loop gain, AOL , and the potential difference between the input voltages, vid = (v1 − v2 ).
Thus internal node voltages are Q = ‘0’ and QB = ‘1’ before the transmission gate based access transistors (MN3/MP3 and MN4MP4) are turned on.
Concentration Over Voltage This voltages drop results from the change in concentration of the reactants at the surface of the electrodes as the fuel is used.
