synchronous clock การใช้

• Nevertheless, the decline of the synchronous clock could not be stopped.
• Some synchronous clocks have an indicator which shows if it has stopped and restarted.
• In a system-synchronous clock topology where a skew-aligned clock is fed to all devices, the criteria is
• A source-synchronous clock topology eliminates two of these factors, T _ { ko } and T _ { skew }.
• Furthermore, Henry Warren invented his master clock at first simply in order to guarantee that his synchronous clock motor would provide accurate time.
• Our article on Utility frequency notes that utilities try to keep quite close to the nominal frequency so that synchronous clocks only deviate a few seconds from actual time.
• You sound very confident, but my impression is that the ubiquitous cheap plug-in alarm clocks in the US are still primarily synchronous clocks tuned to mains frequency.
• In 1928, Hammond founded the Hammond Clock Company, after designing a synchronous clock motor that was inspired by Henry Warren's Telechrons, but was not self-starting.
• If one of two synchronous clocks at A is moved in a closed curve with constant velocity until it returns to A, the journey lasting t seconds, then by the clock which has remained at rest the travelled clock on its arrival at A will be ( 1 / 2 ) tv2 / c2 seconds slow.
• If, on the other hand, you increase the excitation voltage a bit, rather than advancing the phase angle, you would push " VARs " or volt amps reactive onto the grid, providing voltage support to the grid . As for the neighbors synchronous clocks, you would have to have such a big generator that you increased the actual grid frequency to make the clock run faster.
