10.4Definitions
10.4.1Voltage
10.4.1.1User Voltage.The nominal user input voltage (AC) is defined as the root-mean-square (rms) voltage applied. The nominal user input voltage (DC) is defined as the actual positive or negative voltage applied.
10.4.1.2User Voltage Toleranceis the maximum permitted departure from nominal user voltage during normal operations, excluding transient and cyclic voltage variations.
10.4.1.3Transient Voltage Tolerance.A voltage transient (excluding spikes) is a sudden change in voltage which goes outside the user voltage tolerance limits and returns to and remains within these limits within a specified recovery time after the initiation of the disturbance. The transient voltage tolerance is in addition to the user voltage tolerance limits.
10.4.1.4Transient Voltage Recovery Timeis the time elapsed from initiation of the disturbance until the voltage recovers and remains within the user voltage tolerance limits.
10.4.1.5Phases.Shipboard generators generally have their alternating-current circuits arranged to produce three-phase a.c. power with an angular relationship of 120 degrees. Single-phase a.c. power is also available aboard ship.
10.4.2Frequency
10.4.2.1Nominal Frequencyis the steady state, nominal user input frequency in Hertz (Hz).
10.4.2.2Frequency Toleranceis the maximum permitted departure from nominal frequency during normal operation, excluding transient and cyclic frequency variations.
10.4.3Current
10.4.3.1Steady State Currentis full load current in rms amps drawn by the user equipment.
10.4.3.2Start-Up or In-Rush Currentis the turn on, peak current drawn by the user equipment.
10.4.3.3Duration of In-Rush Currentis the time (in milliseconds) from sudden change in current (turn on) until the current recovers to steady state value.
10.4.3.4Harmonic Current Spectrumis the user equipment line currents from the 2nd up to 32nd harmonic (expressed in percent of the fundamental current). A harmonic frequency is a multiple of the fundamental frequency.
10.4.4Power
10.4.4.1Connected Loadis the nameplate rating of all equipment in the systems.
10.4.4.2Steady State Operating Loadis the continuous steady-state power in kW and kVA consumed by the user equipment.
10.4.4.3Transient Operating Loadis the sudden change in power (kW and kVA) consumed by the user equipment.
10.4.4.4Power Factoris the ratio of total watts per phase to the total rms volt-amperes per phase.
10.4.5Leakage Currentis the total rms current that passes from phase to ground with nominal voltage impressed at the nominal frequency.
