The three-phase two element is to measure the condition of three-phase load power to three-phase voltage phase current, from the wiring diagram and principle analysis of calculation formula in this table is visible, not into the current table, counting the three-phase load power, but between ...
A voltage indicating meter is connected between the outputs of two high impedance operational amplifiers, the first of which receives an input signal to be measured through a range setting resistance
These are: • THD+N versus output power • THD+N versus frequency • Gain and phase versus frequency • Integrated noise • Signal-to-noise ratio • Crosstalk versus frequency • Power supply rejection ratio • Supply ripple voltage rejection ratio • Efficiency • Power ...
