In a cable, burried in the Earth, or in open air. This is typically in a raceway (cable-tray or conduit), Installation - Choose the installation method for the circuit. Common conductors are copper and aluminum. Insulation - Select the thermal rating of the insulation on the wire.Ĭonductor - Choose the material used as a conductor in the wire. To calculate ground wire size, use the Ground Wire Size Calculator. For three-phase circuits, four wires are required. Single-phase circuits, three wires are required. This is typically single-phase or three-phase. Phases - Select the number of phases in the circuit. To multiply the nameplate FLA by 1.25 for wire sizing. While three-phase voltages are typically 208V, 230V or 480V.Īmperes - Enter the maximum current in amps that will flow through the circuit. Single-phase voltages are usually 115V or 120V, If you do not allow these cookies, you will experience reduced relevant content.Voltage - Enter the voltage at the source of the circuit.

Software Calibrated, 1MHz to 8GHz, 60 dB RF Power Measurement System Using the AD8318 Logarithmic Detector (CN0150) (pdf)Īnalog Devices is in the process of updating our website.RF Power Calibration Improves Performance of Wireless Transmitters (pdf).Ask The Engineer - 28 Logarithmic Amplifiers-Explained.MT-053: Op Amp Distortion: HD, THD, THD + N, IMD, SFDR, MTPR (pdf).MT-003: Understand SINAD, ENOB, SNR, THD, THD + N, and SFDR so You Don't Get Lost in the Noise Floor (pdf).Buffer Amplifiers, Gain Blocks and Instrumentation Amplifiers (pdf).For display purposes, results of calculations are rounded to the nearest 4 decimal places which should exceed the precision of most measurements. Please be aware of the accuracy limits of this calculator. Tabbing to another field, pressing "Enter" or clicking "Calculate" will recompute all equivalent values. To use this calculator enter your application data in the section provided, then enter the quantity you wish to convert in the appropriate form element. dBm is a power ratio relative to 1mW, dBu and dBV are voltage ratios, relative to 0.775V and 1V, respectively. This calculator interconverts between dBm, dBu, dBV, V PEAK and V RMS (ANSI T1.523-2001 definitions).
